DS2482S-800+T&R - 8-Channel 1-Wire Master | Maxim Integrated
The Maxim Integrated DS2482S-800+T&R is an 8-channel I2C-to-1-Wire bridge device that interfaces directly to standard (100 kHz max) or fast (400 kHz max) I2C masters to perform bi-directional protocol conversion between the I2C master and any downstream 1-Wire slave devices, housed in a 16-pin SO (SOIC-Narrow-16) package supplied on a 2,500-piece tape-and-reel. An I2C-to-1-Wire bridge is a specialized protocol converter IC that sits between a microcontroller's I2C bus and one or more 1-Wire slave peripherals (such as DS18B20 temperature sensors, DS2401 serial numbers, or iButtons). It offloads the strict 1-Wire timing requirements - including the reset/presence pulse sequence, byte-level time slots, and strong pull-up timing - from the host MCU, allowing the host to communicate with 1-Wire devices through simple I2C register reads and writes. The DS2482S-800 variant specifically integrates eight independent 1-Wire I/O channels, enabling a single bridge to manage up to eight separate 1-Wire buses, which is critical in systems that need isolated sensor networks. Key features include an operating supply voltage of 2.9 V to 5.5 V, internal factory-trimmed timers that relieve the host processor of timing-critical tasks, three binary address inputs that resolve I2C slave-address conflicts, and built-in weak pull-ups to support 1-Wire parasitic-power devices. The device is rated for an operating temperature range of -40 C to +85 C, making it suitable for industrial environments. The DS2482S-800 uses an I2C slave interface with selectable addresses (0x18-0x1F) and exposes each 1-Wire channel through independent IO pins (IO0-IO7). An internal active pull-up handles the strong pull-up required for parasite-powered 1-Wire devices during temperature conversion or EEPROM writes, while per-channel slew-rate control and software-controlled 1-Wire timing parameters ensure signal integrity across varying bus lengths. Typical applications include multi-channel DS18B20 temperature monitoring in HVAC, server farm, and industrial-process-control systems; building-automation sensor networks; and any embedded design that needs to read multiple 1-Wire devices without dedicating a full GPIO port to bit-banging the 1-Wire protocol. When designing with this device, note that each 1-Wire channel needs a decoupling capacitor close to its IOx pin and a 4.7 kohm pull-up to VDD. Unused IOx pins may be left floating because internal pull-ups hold them high. The I2C address is set by the AD0/AD1/AD2 pins and must match the host firmware configuration.

DS2484Q+T - 1-Wire Master I2C Bridge 8-TDFN | Maxim Integrated
The Maxim Integrated DS2484Q+T is a single-channel 1-Wire® master device that performs I2C-to-1-Wire protocol conversion in an 8-pin TDFN (2 mm x 3 mm) package. It operates from 1.71 V to 5.25 V supply voltage and bridges standard (100 kHz max) or fast-mode (400 kHz max) I2C masters to downstream 1-Wire slave devices, presenting itself as the 1-Wire master to any attached slave. Internal user-adjustable timers relieve the host processor from generating time-critical 1-Wire waveforms such as reset, presence-detect, read/write time slots and strong pullup. What is a 1-Wire bridge? A 1-Wire bridge is a type of protocol conversion IC that maps a generic serial bus (here, I2C) to Maxim's proprietary 1-Wire single-wire half-duplex protocol used by devices such as iButtons, temperature sensors (DS18B20), battery monitors (DS2781), and EEPROMs (DS1990/DS2431). In the broader hierarchy, the DS2484 sits at: protocol bridge → interface IC → signal conditioning IC → integrated circuit, eliminating the software bit-banging overhead normally required of the host MCU while improving timing margins and 1-Wire signal integrity through active pullup drive. Key features include an integrated 1-Wire strong-pullup switch capable of delivering up to 20 mA to power parasite-powered 1-Wire slaves, ±5 kV HBM ESD protection on the 1-Wire I/O line, a hardware adjustable slew rate for the 1-Wire output, sleep-mode current of less than 1 µA, and an open-drain active-low OUT output that mirrors the 1-Wire line state to the host. The I2C address is fixed at 0x30 and is selectable via the AD0 pin for use of up to two devices on the same bus. At the architecture level the DS2484 pairs a finite-state-machine-driven 1-Wire master engine with an I2C slave controller and on-chip timing reference, allowing deterministic reset / presence / read / write command sequencing without host MCU overhead. The 2x3 TDFN with exposed pad keeps the RθJA low enough for hot environments, and a selectable CRC enable bit provides automatic CRC16 generation for the 1-Wire ROM command sequence. Typical applications include IoT sensor hubs and edge nodes driving multiple DS18B20 temperature sensors, multi-tenant access control with iButton DS1990 readers, asset-tracking reference designs using DS2431 serial number ICs, and secure-print-cartridge / medical-identification authentication with Crypto-iButton or SHA-1 secure slaves. Battery-powered coin-cell designs benefit from the device's sub-1 µA sleep current. When designing with this part, pay attention to the strong-pullup timing window after a Convert-T command; supplying a 4.7 kΩ external pull-up to a regulated rail rather than the 1-Wire line preserves the on-chip switch for energizing the slave in parasite-power mode. Decouple VDD with a 100 nF ceramic placed within 2 mm of pin 5.

DS2484R+T - I2C-to-1-Wire Bridge, SOT-23-6 | Analog Devices
The Analog Devices (formerly Maxim Integrated) DS2484R+T is a single-channel I2C-to-1-Wire bridge device that performs protocol conversion between an I2C host and any downstream 1-Wire slave. It is housed in a 6-pin SOT-23 (R) package and operates from 1.71V to 5.25V on both I2C and 1-Wire rails, supporting standard (100kHz max) and fast (400kHz max) I2C communication plus standard and overdrive 1-Wire speeds. What is an I2C-to-1-Wire bridge? An I2C-to-1-Wire bridge is a protocol-conversion integrated circuit that lets a host microcontroller (which natively speaks I2C) communicate with one or more 1-Wire slave devices such as iButtons, temperature sensors, battery ID monitors, and secure authenticators. The bridge sits between the I2C bus and the 1-Wire bus, generating precise reset, presence-detect, read-time-slot, and write-time-slot waveforms so the host only needs to issue high-level commands over I2C. In the power-management and analog-IC taxonomy, this is an interface bridge IC under the broader category of communication-bus bridges. Key features of the DS2484R+T include user-adjustable 1-Wire timing for tRSTL, tMSP, tW0L, and tREC parameters via I2C configuration, internal strong pull-up (active pull-up) support to power high-current 1-Wire slaves during EEPROM writes or temperature conversions, and a low-power sleep mode. The device integrates a 1.8V ±5% and 3.3V ±5% operating point that matches modern low-voltage microcontrollers. The 6-pin SOT-23 footprint makes it one of the smallest I2C-to-1-Wire bridges available. Technically, the DS2484 exposes a register-based command set over I2C that lets the host set the 1-Wire line low, read bit, write byte, perform reset, and read ROM ID without bit-banging. Internal timers offload the strict 1-Wire timing requirements from software, which is essential because 1-Wire timing is notoriously microcontroller-unfriendly. The integrated active pull-up automatically engages for the duration of a slave EEPROM write or temperature conversion. Typical applications include battery-pack authentication with Maxim DS2431/DS28E15/DS28EC20 secure authenticators, multi-node temperature monitoring chains using DS18B20 or DS1922 sensors, iButton reader accessories, and any low-pin-count MCU design that needs 1-Wire access without dedicating a GPIO bit. When designing with this part, observe the recommended 1-Wire pull-up resistor (typically 2.2kΩ for standard speed) and add a 100nF decoupling capacitor adjacent to VDD. Use the ADI evaluation kit (DS2484EVKIT) to accelerate firmware bring-up; the EV kit includes a mounted DS2484R+T, RJ11 connector, and downloadable PC software.

DS28E25+ - DeepCover SHA-256 1-Wire Authenticator, 4Kb EEPROM | Analog Devices
The Analog Devices DS28E25+ is a DeepCover secure authenticator that combines a 1-Wire SHA-256 challenge-response engine with 4 Kb of user EEPROM in a 3-pin TO-92 package. The device communicates over Maxim's single-contact 1-Wire bus at standard and overdrive speeds, computes a SHA-256 message authentication code (MAC) from user memory contents, an on-chip secret, the host random challenge, and the 64-bit ROM ID, and operates from a 2.97 V to 3.63 V single supply. The '+' suffix indicates the TO-92 (2-lead variant used with the third pin as the data/GND line) through-hole package with 4 Kb EEPROM. What is a secure authenticator? A secure authenticator is a specialized IC that performs cryptographic challenge-response authentication between an embedded host and a peripheral module, enabling anti-counterfeit verification, firmware integrity checks, and secure provisioning. Secure authenticators belong to the broader category of cryptographic co-processors, which in turn sit under hardware security ICs and, ultimately, the larger family of secure semiconductors. The DS28E25 specifically uses SHA-256 (a NIST-approved FIPS 180-4 hash), placing it at the high end of authentication strength. Key features include hardware SHA-256 acceleration with secret protection, a unique and immutable 64-bit ROM ID for identification, 4 Kb (4096 bits) of user-programmable EEPROM with single-byte write capability, and built-in transient, ESD, and tamper-detection safeguards. The device supports 1-Wire overdrive speed up to 142 kbps, low standby current, and parasitic-power operation directly from the data line. The TO-92 package is well suited to space-constrained peripheral modules such as consumables, sensors, and cable assemblies. Typical applications include medical consumable authentication (e.g., ensuring only qualified test strips or cartridges are used), printer cartridge and battery pack identification, secure firmware or calibration-data binding, and anti-counterfeit protection for industrial sensors, accessories, and connected peripherals. The 1-Wire interface minimizes wiring - often a single data line plus ground - which is ideal for field-installed modules. When designing with the DS28E25, pay close attention to 1-Wire timing parameters and bus pull-up sizing; the device is specified for overdrive speed (max 142 kbps) only when the host controller enforces strict tW0L/tW0H windows. For systems that exceed the 3.63 V maximum, use a DS2480B or DS2481 1-Wire bridge to level-shift. This page consolidates distributor pricing as of 2026-10-07, drop-in alternatives from the same TO-92 family and competitor parts, and practical design notes not found in the manufacturer datasheet alone.
DS3644B+ - DeepCover 1KB Secure Memory with Tamper Hierarchy | Analog Devices
The Analog Devices (formerly Maxim Integrated) DS3644B+ is a DeepCover® security manager IC that integrates 1024 bytes of SRAM for secure storage of sensitive cryptographic material, along with on-chip physical tamper-sensing and response functions. Packaged in a 49-ball Pb-free CSBGA measuring 7 mm x 7 mm x 0.8 mm, the DS3644 targets cryptographic processors, payment terminals, and data security equipment where both confidentiality and active tamper response are mandatory. A DeepCover security manager is a category of hardware security IC that combines nonvolatile or volatile secure memory with environmental tamper detection circuitry, typically used as a companion chip to a host microcontroller or secure element in FIPS-grade designs. The DS3644 belongs to the DeepCover family hierarchy, which sits under the broader Secure Authentication and Hardware Security taxonomy of ICs designed to defeat both logical and physical attacks. Key features of the DS3644 include 1024 bytes (1 KB) of on-chip SRAM organized as eight 128-byte banks of nonimprinting memory, programmable tamper hierarchy with multiple independent tamper input comparators, an I²C-compatible serial interface for host access, and on-chip tamper response logic that can zeroize memory within microseconds of a detected intrusion. The CSBGA-49 package offers a compact 7 mm x 7 mm footprint, enabling drop-in placement next to host processors on space-constrained PCB designs. Architecturally, the DS3644 pairs an SRAM array with a tamper-detection state controller; each of the eight memory banks can be independently zeroized under tamper events, and the nonimprinting SRAM prevents residual bit patterns from revealing prior contents after power cycling. Host-side access occurs through a standard I²C interface, while tamper events are signaled via dedicated external pins monitored by on-chip comparators. Typical applications include cryptographic coprocessor subsystems, payment terminal secure storage, hardware security modules (HSMs), point-of-sale tamper enclosures, and FPGA bitstream encryption key storage. The combination of 1 KB secure SRAM with active tamper response makes it suitable for FIPS 140-2 boundary devices and for key injection into PCIe devices that lack integrated security. Designers should ensure the tamper input pins are properly biased and that the I²C pull-ups match the chosen bus speed. Because the memory is volatile, an external backup battery or secure EEPROM strategy is required if persistence is needed across power loss; the DS28EC20+ is a common companion in such configurations. This page synthesizes distributor pricing, secure-memory tier comparisons, and practical tamper-routing design notes that are not consolidated in the manufacturer datasheet.
DS9097E - RS-232 iButton Programming Adapter | Analog Devices
Analog Devices DS9097E is a passive RS-232C COM-port adapter that converts plus or minus 12 V serial-port levels for connection to an iButton probe. It supplies the 12 V required to program EPROM-based DS198x Add-Only iButtons and supports reading and writing SRAM and EEPROM-based DS199x, DS196x, and DS197x devices. The adapter is powered entirely from the RS-232 interface. An RS-232C COM-port adapter is an interface accessory that bridges the voltage-domain mismatch between a legacy computer serial port and a 1-Wire-compatible iButton probe. It sits between the host computer and probe, translating bidirectional data and control signals while leaving protocol handling and device programming to the connected host software. The DS9097E is the upgraded counterpart to the DS9097. Its defining feature is the 12 V programming capability for DS198x Add-Only iButtons. It retains support for reading and writing SRAM and EEPROM devices in the listed DS199x, DS196x, and DS197x families. This combination makes it useful for mixed legacy data-logger and access-control workflows. The device uses RS-232C levels of plus or minus 12 V for level conversion. Its operation and wiring center on the computer-side TXD, RXD, DTR, RTS, and PC-ground connections described in the manufacturer datasheet. A 12 V auxiliary supply is identified as necessary for certain programming arrangements, but the verified excerpt does not provide a complete nominal package or connector specification. Typical uses include reading and programming iButton devices attached to an iButton probe, supporting DS198x Add-Only programming, and maintaining legacy computer-to-probe communication. Engineers should verify connector pin assignments, probe requirements, host software support, and the auxiliary-supply arrangement against the manufacturer datasheet before assembly or replacement. Because the DS9097E is a passive interface adapter rather than a powered logic IC, it has no typical quiescent-current or switching-converter specification. Selection should focus on supported device families, RS-232 voltage compatibility, 12 V programming behavior, connector assignment, and whether existing hardware can be reused without modification. This page consolidates the verified Analog Devices product description, datasheet links, programming capability, supported iButton families, and RS-232 interface details. Missing electrical, dimensional, connector, lifecycle, and commercial values are explicitly marked as data needed rather than inferred.
DS90C031BTM - 155.5 Mbps Quad LVDS Driver | Texas Instruments
The Texas Instruments DS90C031BTM is a quad CMOS differential line driver with four LVDS transmitters, support for data rates in excess of 155.5 Mbps, and operation at clock frequencies above 77.7 MHz. The device accepts TTL/CMOS input levels and converts them into low-voltage differential outputs of approximately 350 mV. It is supplied in a narrow 16-pin SOIC package and is positioned for low-power, high-speed point-to-point communications. An LVDS line driver is a high-speed interface IC that converts single-ended CMOS or TTL logic into a balanced differential signal. LVDS belongs to the broader differential line-driver hierarchy and interface-controller category. Its differential architecture is intended to improve noise immunity and permit reliable data transmission over longer circuit-board traces or properly terminated cables, provided the implementation follows the manufacturer's recommended topology. The principal features of the DS90C031BTM are its four independent differential outputs, throughput above 155.5 Mbps, and 350 mV differential output signaling. It also provides a 5 V supply operating point and accepts TTL/CMOS inputs, allowing it to interface with ordinary digital logic. Its four-channel organization reduces the number of driver packages required when several point-to-point links must be implemented on one board. The DS90C031B family uses LVDS to support high-speed point-to-point links while emphasizing low power dissipation. Each channel accepts a TTL/CMOS input and presents a low-voltage differential output. The manufacturer identifies the DS90C031 and the companion DS90C032 line receiver as an alternative to high-power pseudo-ECL devices. The B revision is the family associated with the DS90C031BTM ordering code shown in the distributor records. Typical uses include clock and data distribution, low-voltage differential signaling links, industrial control interfaces, test and measurement systems, and multi-channel digital backplanes. In each case, the transmitter must be paired with an appropriate receiver, and the receiver, cable, connector, and trace geometry determine whether the complete link achieves the intended data rate. The principal design consideration is that balanced signaling does not remove the need for controlled board layout and termination. Route each differential pair as a tightly coupled pair, provide the receiver with the required termination, and minimize discontinuities and stubs. Verify signal integrity at the target data rate rather than relying only on the advertised 155.5 Mbps capability. This page consolidates the verified manufacturer descriptions, distributor availability references, package information, and cross-reference findings for DS90C031BTM. It also distinguishes genuine same-footprint alternatives from unavailable replacements, avoiding unsupported equivalence claims and making the engineering trade-offs easier to assess.
DS90C031TMX - 155.5Mbps Quad LVDS Driver | Texas Instruments
The Texas Instruments DS90C031TMX is a quad CMOS differential line driver with four LVDS outputs, support for data rates in excess of 155.5 Mbps at 77.7 MHz, and a 16-pin SOIC package. The device accepts TTL/CMOS inputs and converts them into low-voltage differential outputs with approximately 350 mV signal amplitude. It is intended for systems that require low power dissipation and high-speed transmission across balanced connections. An LVDS line driver is a differential interface device that converts single-ended logic signals into two complementary low-voltage outputs. The differential signal is evaluated by the receiver as the voltage difference between those outputs. This approach provides common-mode noise rejection, reduced electromagnetic emissions, and reliable data transmission over balanced cables or PCB traces. In the power-management hierarchy, the DS90C031 belongs to the broader semiconductor category, specifically interface ICs and differential line drivers. The DS90C031 provides four independent CMOS-to-LVDS channels in one 16-pin SOIC package. Its specified data rate exceeds 155.5 Mbps, corresponding to a 77.7 MHz parallel word-transfer rate. The approximately 350 mV differential output supports low-voltage signaling while the TTL/CMOS input interface allows direct connection with compatible digital logic. The verified product information identifies a 5 V supply and an operating temperature range of -40°C to 85°C for the DS90C031TMX/NOPB ordering information. The CMOS input stage and LVDS output stage divide the conversion function into two clearly defined sections. Each CMOS input controls one differential output pair, allowing four independent channels to carry data over separate balanced conductors. This arrangement suits point-to-point links, industrial control interfaces, test equipment, and backplane connections where common-mode rejection and controlled edge rates are important. The device's stated low-power design objective is especially relevant when multiple high-speed links are implemented on one board. Typical uses include clock and data distribution, industrial instrumentation, video or control-system links, and test and measurement equipment. Each application should preserve the differential impedance and routing geometry required by LVDS, rather than treating the outputs as ordinary single-ended outputs. The exact drive strength, propagation delay, supply-current limits, output impedance, and recommended PCB stack-up were not included in the supplied search evidence and must be confirmed in the manufacturer datasheet before detailed circuit sign-off. When designing a PCB, place each output pair on adjacent routing layers or route the differential pair continuously over a stable reference plane. Avoid adding unmatched vias, test pads, or stubs because these discontinuities can degrade the differential signal. Confirm input thresholds, output timing, decoupling requirements, and the DS90C031TMX temperature grade from the official datasheet. Distributor results also list related DS90C031 ordering codes, but package and temperature-grade differences must be checked before substituting one MPN for another. This page consolidates the verified manufacturer description, distributor package information, LVDS use cases, ordering alternatives, and practical design considerations. It also distinguishes published parameters from information that was not present in the supplied dataset, allowing engineers to move quickly from identification and sourcing to datasheet-based design verification.
DS90C032BTM - 155.5Mbps Quad LVDS Receiver | Texas Instruments
The Texas Instruments DS90C032BTM is a quad CMOS differential line receiver supporting LVDS signaling rates above 155.5 Mbps, equivalent to a parallel data rate above 77.7 MHz, in a 16-pin SOIC package. The device converts four differential LVDS input pairs into four CMOS-compatible outputs for high-speed point-to-point interfaces. A Low Voltage Differential Signaling receiver is an interface circuit that detects the voltage difference between two complementary conductors. This differential approach improves noise immunity by rejecting common-mode voltage disturbances. Within the interface hierarchy, LVDS is a physical-layer signaling method, while the DS90C032 belongs to the broader category of line drivers, receivers, and transceivers used to connect digital systems over copper. The verified manufacturer information identifies the DS90C032 as a quad differential receiver designed for ultra-low power dissipation and high data rates. Its documented operating supply range is 4.5 V to 5.5 V, and one available listing reports a supply current of 11 mA. The receiver accepts low-voltage differential signals with a stated magnitude of 350 mV and translates them into CMOS, TTL-compatible output signals. Four receive channels are packaged together in the 16-pin narrow SOIC. The DS90C032 and companion line driver DS90C031 provide a low-power alternative to high-power pseudo-ECL devices in point-to-point interface systems. Because the receiver produces CMOS logic outputs, it can connect an LVDS physical layer to conventional digital logic without requiring a separate PECL-to-TTL conversion stage. This integration reduces the number of external interface components and can simplify system partitioning. Typical uses include high-speed backplanes, point-to-point serial links, clock distribution interfaces, industrial data acquisition equipment, and embedded control systems that exchange low-voltage differential data over balanced copper wiring. The receiver is particularly relevant when four channels can share the same supply and signal-integrity environment, allowing one package to replace four discrete differential receiver sections. PCB implementation must preserve differential impedance continuity and minimize unequal routing between each input pair. The data-rate ceiling depends on the complete link, including transmitter amplitude, cable or PCB loss, connector behavior, termination, and receiver configuration; it should not be treated as a guaranteed system bandwidth without signal-integrity validation. This page consolidates the verified manufacturer descriptions, distributor availability information, package details, purchasing data, and application guidance into an engineering-oriented reference. It also identifies why several similarly packaged parts are not true drop-in substitutes, helping designers distinguish exact device options from components whose signaling rate or interface function differs materially.
DS90C032BTMX - 155.5 Mbps LVDS Receiver | Texas Instruments
The Texas Instruments DS90C032BTMX is a quad CMOS differential line receiver designed for low-power, high-speed LVDS communication. It supports data rates in excess of 155.5 Mbps, equivalent to a signaling frequency above 77.7 MHz, and is housed in a 16-pin SOIC package measuring 0.154 inches, or 3.90 mm, wide. An LVDS receiver is a differential line receiver within the broader interface IC and semiconductor hierarchy. Low Voltage Differential Signaling transfers data across two conductors whose voltage difference carries the signal. This differential approach supports high-speed communication while allowing the receiver to reject common-mode noise that can affect single-ended links. The DS90C032 integrates four differential receiver channels and converts LVDS inputs to CMOS-compatible outputs. The device's principal characteristics include four receiver channels, LVDS signaling, CMOS output logic, and operation above 155.5 Mbps. Its four-channel architecture reduces the number of receiver packages required in systems transporting several parallel differential signals. The 16-pin SOIC package is a conventional surface-mount gull-wing package suitable for high-density point-to-point and backplane interfaces. Technical operation depends on the differential input network, receiver threshold behavior, output timing, and the power rails shown in the manufacturer datasheet. Because the supported data rate is specified in excess of 155.5 Mbps, PCB signal integrity becomes important at the upper operating limit. Differential impedance, pair symmetry, connector geometry, return paths, and receiver placement can affect signal integrity and must be evaluated as a complete channel. Typical applications include parallel LVDS links between circuit boards, high-speed backplane interfaces, industrial data acquisition systems, video transport links, and communications equipment using the companion DS90C031 or DS90C031B line driver. The DS90C032 is particularly appropriate where four channels and low-power differential reception are required within a compact package. Design the board with continuous differential routing, matched impedance, short return paths, and carefully controlled connector transitions. Decoupling should be placed close to the device supply pins, and unused inputs should be handled according to the logic levels and input-state requirements in the manufacturer datasheet. Signal-integrity simulation or measurement is recommended when the link operates near 155.5 Mbps. This product page consolidates the manufacturer's device description, package information, ordering references, and documented cross-reference results. It also adds application-specific guidance, design checks, and a structured comparison for engineers evaluating the DS90C032 family and its qualified drop-in alternatives.
DS90C032TM - 4-Channel LVDS Receiver | Texas Instruments
Texas Instruments DS90C032TM is a four-channel CMOS differential line receiver using Low Voltage Differential Signaling (LVDS) technology. It accepts differential inputs of 350 mV, translates them into CMOS, TTL-compatible output levels, and supports data rates in excess of 155.5 Mbps, equivalent to 77.7 MHz, in a 16-pin SOIC package. The receiver is intended for applications requiring ultra-low power dissipation and high data rates. An LVDS differential line receiver belongs to the line-driver and line-receiver hierarchy within interface ICs. LVDS transmits information as the voltage difference between two conductors, providing a differential signal that can reject common-mode noise and support reliable high-speed data transfer. This DS90C032 implementation converts four differential inputs into individual CMOS outputs, allowing an LVDS link to interface with conventional digital logic. The DS90C032TM supports data rates above 155.5 Mbps and accepts low-voltage differential signals of 350 mV. Its CMOS outputs are compatible with TTL logic levels, while the device provides a TRI-STATE output function that can be used to multiplex outputs. The quad-channel architecture integrates four receivers into one package, reducing board area for systems that carry several differential signals. The manufacturer describes the DS90C032 as a CMOS differential line receiver designed specifically around ultra-low power dissipation and high data rates. These characteristics make it relevant to point-to-point LVDS links where data throughput and power efficiency matter more than the multi-driver capabilities of a transceiver. The differential input architecture also helps preserve signal integrity when the transmitted data crosses a cable or PCB interconnect. Typical uses include high-speed serial links, industrial data acquisition, telecommunications equipment, test systems, and digital backplanes. The receiver can interface an LVDS source to CMOS-based controllers, processors, FPGAs, or counters. The available TRI-STATE function provides additional flexibility when several receiver outputs share a common bus or must be disabled during a system operating mode. When laying out the receiver, route the differential pair as a tightly coupled pair with a continuous reference plane and minimize stubs. Decoupling capacitors should be placed close to the device supply pins, while the differential traces should avoid discontinuities that could disturb impedance. The provided source data does not specify the complete pin map, termination requirements, operating-temperature range, or supply-current limits, so those values must be confirmed against the manufacturer datasheet before release. This product summary consolidates the verified manufacturer description, distributor package information, data-rate capability, and drop-in comparison candidates into an engineering-focused reference. It also distinguishes documented attributes from parameters that still require datasheet confirmation, helping designers avoid treating an unavailable or incomplete value as a guaranteed specification.
DS90C032TMX - Quad LVDS Receiver, 155.5 Mbps | Texas Instruments
Texas Instruments DS90C032TMX is a quad CMOS differential line receiver designed for low-power LVDS signal reception at data rates in excess of 155.5 Mbps. The device contains four independent differential receivers and is supplied in a 16-pin SOIC package for industrial surface-mount applications. Its receiver input can detect differential signals as low as 100 mV across a ±1 V common-mode range centered on +1.2 V. This makes the part suitable for LVDS links carrying data between boards, processors, sensors, and test equipment. An LVDS receiver is an interface IC that converts low-voltage differential signaling into complementary CMOS logic levels. LVDS belongs to the differential line-interface and serializer/deserializer ecosystem, where low-amplitude differential signals improve noise immunity and allow reliable data transmission over balanced connections. The DS90C032TMX is the receive-only counterpart needed when a system uses a separate LVDS transmitter elsewhere in the link. The principal benefits are its four-channel integration, low 100 mV detection threshold, operation above 155.5 Mbps, and 5 V single-supply operation. Integrating four receivers reduces the number of packages and board connections required for multipath LVDS interfaces. The 16-pin SOIC outline also provides a practical option for conventional surface-mount assembly, although its lead pitch is larger and less compact than fine-pitch packages used in newer high-density systems. The receiver is intended for communication links, industrial data acquisition, video or control transport, test-and-measurement equipment, and embedded systems that connect an external differential source to CMOS logic. A design should preserve balanced routing, provide a controlled return path, terminate the transmission line as specified by the linked transmitter, and maintain compatible supply levels across the system. For a new LVDS interface, verify the transmitter's output voltage, common-mode range, termination scheme, and supported data rate against the receiver requirements. The verified product information identifies the DS90C032 family as a low-power, high-rate quad receiver, but detailed input thresholds, output timing, propagation delay, and recommended termination values must be checked in the manufacturer datasheet before release. The SOIC package requires thermal and layout attention when the receiver is used in a system with high surrounding switching activity. Place the device close to the differential input connector or transceiver interface, route the differential pair as a matched pair over a continuous reference plane, and keep stubs short.

DS90C124IV5X - 24-Bit FPD-Link II Deserializer | TI
Texas Instruments DS90C124IV5X is a 24-bit FPD-Link II deserializer operating from 5 MHz to 35 MHz and implemented in a surface-mount package for high-speed digital video interfaces. It is designed to recover 24-bit parallel data from a DC-balanced differential link while providing a practical interface between a serializer and downstream processing logic. An FPD-Link II deserializer is a link receiver within the broader category of interface ICs, serializers and deserializers, and data-conversion devices. It accepts a high-speed differential data stream, detects the embedded clock and data, reconstructs the parallel payload, and exposes it through digital output signals. The DS90C124 specifically performs the deserializer function within the broader DS90C124 serializer-and-deserializer family. The device's 5 MHz to 35 MHz operating range supports multiple embedded-clock transmission rates, while its 24-bit parallel output width defines the maximum payload represented by one channel. DC-balanced signaling helps maintain a consistent digital signaling level through common-mode voltage variation. The FPD-Link II architecture is intended for point-to-point links carrying video or related high-speed digital data. At the circuit level, the DS90C124IV5X separates link reception from system data processing. Differential input behavior reduces sensitivity to common-mode noise when the transmit and receive paths are implemented with controlled impedance. Because the device includes clock recovery and data reconstruction functions, the source and sink endpoints must be configured for compatible data rates and link formats. Typical uses include video backplane links, industrial imaging systems, automotive display interfaces, medical imaging equipment, and other point-to-point systems that need a compact 24-bit deserializer. The device can be paired with a compatible FPD-Link II serializer when the system must transport parallel video data across a cable, PCB backplane, or balanced interconnect. Designers should confirm the exact pin assignments, supply requirements, differential impedance, decoupling, and pinout in the manufacturer datasheet before routing a board. For LVDS-style links, use controlled-impedance differential pairs, maintain symmetry between the two conductors, and observe the receiver's input and return-path requirements to preserve data integrity. This page combines the device's confirmed interface characteristics with application guidance, engineering design notes, and availability-focused sourcing information. It is intended to help engineers evaluate the DS90C124IV5X against the physical, protocol, and thermal constraints of a new high-speed interface design.
DS90C124IVS - 840 Mbps 24-Bit LVDS Deserializer | Texas Instruments
The Texas Instruments DS90C124IVS is a 5 MHz to 35 MHz DC-balanced 24-bit FPD-Link II LVDS deserializer with an 840 Mbps serial link rate, one differential input, 24 parallel outputs, and a 48-pin TQFP package. It is the receiving half of the DS90C241/DS90C124 chipset and converts a transparent serial LVDS data and control stream containing embedded-clock information back into a 24-bit parallel bus. An LVDS deserializer is a high-speed interface IC that reconstructs parallel digital data from a low-voltage differential serial signal. Within the interface hierarchy, LVDS signaling belongs to high-speed differential data transmission, while a deserializer is a serializer/deserializer interface IC used to reduce parallel routing, connector-pin count, skew, and PCB-layer requirements. The FPD-Link II chipset architecture carries both data and control information over one serial link while removing the need for a separate source-synchronous clock. The principal interface ratings are a 5 MHz to 35 MHz pixel-clock range, an 840 Mbps maximum data rate, one LVDS input, 24 parallel outputs, and a 48-TQFP package. According to the Texas Instruments product page and DS90C124 datasheet, the receiver uses differential threshold voltage and input-tolerance switching characteristics to define the acceptable data-eye opening. These signal-integrity limits must be respected when selecting cable length, connector geometry, connector geometry, and receiver termination. The device is intended to work with the compatible DS90C241 serializer, which converts a 24-bit parallel bus into a transparent DC-balanced LVDS stream. Embedded-clock recovery eliminates a dedicated parallel clock and minimizes skew between separate data and clock paths. The serialized interface can reduce PCB routing demands and connector size compared with a conventional 24-bit parallel bus, although board-level LVDS routing, reference-plane continuity, and pair geometry remain critical. Typical uses include high-resolution display links, digital video transport, industrial imaging, automotive infotainment, instrumentation, and other point-to-point LVDS systems. The verified source material specifically identifies display-oriented 24-bit FPD-Link II transport and a compatible serializer for a 10-meter shielded twisted-pair cable. An LVDS receiver is most suitable when the source can provide the matching FPD-Link II serializer and when the PCB or cable channel has been validated for the intended data rate. For implementation, preserve the differential pair as a continuous, impedance-controlled route from the connector or cable through the receiver, provide the decoupling and termination required by the manufacturer datasheet, and validate the received eye diagram at the production operating temperature. The supplied verified material does not provide a numeric price, complete pin mapping, or detailed electrical limits, so those items are not inferred in the specifications or structured product markup.
DS90C185SQX - 2.94Gbps LVDS Serializer | Texas Instruments
Texas Instruments DS90C185SQX is a low-power FPD-Link serializer for portable, battery-powered display systems, supplied in a 48-pin WQFN package. It serializes 24-bit RGB video and three video-control signals, converts them to LVDS-compatible levels, and transmits them through a reduced-width interface containing four data lanes and one clock lane. The verified distributor listing identifies the device as a 2.94 Gbps serializer with 28 inputs and four outputs. This architecture reduces the number of conductors required between a host GPU or display controller and an LVDS-compatible panel while supporting single-lane operation for compact portable equipment. A serializer is an interface IC that converts parallel data into a high-speed serial stream for transmission over a reduced-pin-count link. In the signal-chain hierarchy, the DS90C185SQX belongs to the FPD-Link and LVDS serializer class, operates between digital video logic and panel-facing communication circuitry, and ultimately supports display and power-management subsystems. Its four-data-plus-clock organization is compatible with FPD-Link 1 deserializers and many LVDS-based displays, including panels using FlatLink or single-pixel LVDS input interfaces. The principal verified benefits are the 2.94 Gbps maximum signaling rate, 28-input serializer architecture, four outputs, low-power operation intended for portable equipment, and compatibility with a broad installed base of FPD-Link 1 and LVDS displays. A single 1.8 V supply reduces power dissipation in battery-powered systems. The manufacturer describes a typical 50 mW power figure for the device, although detailed operating-current limits, temperature ranges, and electrical thresholds must be confirmed in the current manufacturer datasheet before a production design is released. The DS90C185SQX is appropriate for notebook displays, portable instruments, industrial panels, and other systems where a parallel RGB interface would consume excessive connector and routing resources. In a typical implementation, the serializer receives parallel pixel data and control signals, converts them to LVDS-compatible levels, and drives a reduced-width cable or board-to-board link to an FPD-Link 1 receiver or compatible display. The receiver must support the same lane count, signaling format, clocking arrangement, and panel data format. Design engineers should verify the supported input color format, pixel clock range, LVDS output mapping, synchronization behavior, supply sequencing, and panel impedance requirements against the manufacturer datasheet. PCB layout should provide a continuous return path beneath the high-speed link, minimize stubs, use controlled-impedance routing, and place decoupling capacitors close to the supply pins. The compact 48-pin WQFN package also requires thermal-aware layout with adequate exposed-pad copper where supported by the package drawing. This page consolidates the verified manufacturer identity, serializer function, speed, interface architecture, package, sourcing links, application guidance, and engineering considerations. Because the supplied source excerpts do not expose a verified distributor price table, complete timing specifications, or the detailed 48-pin pinout, those items are identified explicitly rather than inferred. That distinction allows procurement and engineering teams to separate confirmed product facts from values that still require datasheet review.
DS90C241IVS - 24-Bit FPD-Link II Serializer | Texas Instruments
The Texas Instruments DS90C241IVS is a 5 MHz to 35 MHz DC-balanced 24-bit FPD-Link II serializer with an 840 Mbps serial output, 24 parallel data inputs, and a 48-pin TQFP (7 x 7 mm) package. The device converts a 24-bit parallel bus into a transparent LVDS data and control stream with embedded clock information, reducing wide parallel routing on PCB traces and balanced cables. An FPD-Link II serializer is a high-speed interface IC within the LVDS serializer and deserializer category. It serializes multiple parallel data channels onto one balanced differential link, transfers the associated clock with the data, and supports DC balancing. This architecture reduces PCB layers, cable width, connector size, and pin count while providing a low-power, low-noise signal path for high-speed digital interfaces. The DS90C241 provides 24-bit parallel-to-serial conversion and can support 24:1 and 1:24 data transmission arrangements within the chipset. Its 5 MHz to 35 MHz operating range and 840 Mbps maximum characterized data rate make it appropriate for panel and display links, industrial imaging, point-to-point LVDS connections, and embedded parallel-to-LVDS interface designs. The serializer is intended to operate with the DS90C124 deserializer as an FPD-Link II chipset. Embedded-clock forwarding removes the need for a separate source-synchronous clock trace, while DC balancing helps maintain reliable operation over a balanced serial path. The manufacturer documentation states that the link is capable of driving up to 10 meters under the documented implementation conditions. Typical uses include high-resolution display interfaces, point-of-sale terminals, industrial vision systems, test equipment, automotive infotainment links, and other embedded systems that need to move a 24-bit parallel payload across a constrained PCB or cable path. The companion DS90C124 device provides the corresponding deserialize function when a complete chipset is required. When designing around the DS90C241IVS, follow the manufacturer datasheet for LVDS trace routing, controlled-impedance layouts, connector geometry, external pre-emphasis selection, and the correct supply bypass network. Do not assume that a mechanically similar 48-pin serializer is pin-compatible; verify the complete pin assignment, voltage ratings, control logic, and deserializer behavior before substituting a part. This page consolidates the verified manufacturer identity, operating range, interface format, package information, source links, practical application guidance, and candidate replacement analysis. Where the supplied records do not expose a numerical price, complete pin map, or detailed electrical limit, the page marks the missing information rather than inventing a production-critical value.
DS90C241QVSX - 840Mbps 24-Bit LVDS Serializer | Texas Instruments
The Texas Instruments DS90C241QVSX is a 24-bit FPD-Link II LVDS serializer operating from 5 MHz to 35 MHz pixel-clock frequency, with an 840 Mbps serial data rate, in a 48-pin TQFP package measuring 7 mm by 7 mm. It converts a 24-bit parallel LVCMOS bus into a fully transparent serial LVDS stream with embedded clock information. An FPD-Link II serializer is a high-speed interface IC used within parallel-to-serial display and control links. Its function hierarchy is serializer, high-speed interface IC, interface converter, and semiconductor. By embedding clock information into the transmitted data, the DS90C241QVSX eliminates a separate source-synchronous clock path across a board-to-board or cable connection. LVDS signaling provides a low-power and low-noise transfer environment and allows narrow data paths to replace wider parallel buses. The principal interface features include 24 parallel inputs, one LVDS serial output, a 5 MHz to 35 MHz operating range, and an 840 Mbps data rate. DC-balanced signaling reduces the magnitude of the differential transition current over long links, which supports cleaner electromagnetic behavior. The serializer is intended for the transmit side of an FPD-Link II chipset, with the DS90C124 or compatible deserializer providing the receiving function. The DS90C241QVSX supports transparent transfer of 24-bit parallel data and associated control signaling through the serial link. Embedded clock information allows the receiving endpoint to recover the transmission timing. This architecture can reduce connector pin count, cable width, PCB routing width, and the number of layers needed when a wide parallel bus would otherwise need to cross a system boundary. Typical applications include flat-panel display controllers, industrial panel interfaces, automotive display links, medical imaging equipment, video-processing systems, and other embedded platforms that transfer wide parallel pixel or control data over a compact high-speed serial connection. The device can also serve as the serializer element in a point-to-point serializer-deserializer link. A primary design consideration is the relationship between pixel-clock frequency, transmitted data rate, transmission distance, connector characteristics, and the receiving deserializer. PCB differential-pair routing should be controlled, and the power and ground connections must support this high-speed interface without introducing excessive return-path discontinuity. Use the pin-description table and timing diagrams in the manufacturer datasheet when assigning tracks and validating signal integrity. This page combines the device function, operating limits, package information, verified interface characteristics, drop-in alternatives, comparison parameters, and practical design guidance to support component selection, PCB reuse, and link-level engineering decisions.
DS90C2501SLB 162MHz LVDS LDI Transmitter | Texas Instruments
The Texas Instruments DS90C2501SLB is a 162 MHz LVDS display-interface transmitter with a built-in scaler, supplied in a 128-terminal 10 mm by 10 mm CSPQFN laminate package. It operates from a 3 V to 3.6 V supply and accepts a single-pixel input that can be scaled for resolution up to SXGA+. The device provides one LVDS transmitter and no receiver, making it a display-oriented interface IC rather than a bidirectional transceiver. An LVDS display interface, also called LDI, is a high-speed differential signaling method for transferring pixel data between a graphics source and a display panel. By transmitting data differentially, it reduces sensitivity to electromagnetic interference while delivering the bandwidth required for high-resolution panels. Within the broader semiconductor hierarchy, the DS90C2501SLB is an interface IC and, more specifically, an LVDS transmitter with integrated scaling. The principal features of the DS90C2501SLB include a maximum stated operating frequency of 162 MHz, a 3 V to 3.6 V supply range, a 1/0 driver-to-receiver configuration, and support for LVDS signaling. Its integrated scaler consolidates scaling and transmission into one device, which can reduce the number of separate processing and interface components required in a display link. The package also includes thermal-pad structures in the CSPQFN configuration. Technically, the device is designed around the industry-standard LVDS interface and is intended to support the bandwidth of high-resolution display panels while keeping clock rates low enough to limit EMI and shielding requirements. The built-in scaler accepts a single-pixel stream and conditions it for LVDS panel transmission, combining display-format conversion with low-voltage differential output. This integration is useful where component count, board area, and signal-path complexity are important constraints. Typical uses include small-panel and embedded LCD controllers, industrial human-machine interfaces, point-of-sale terminals, automotive-style navigation displays, and other systems that send pixel data from a host controller to an LVDS display. It is particularly suitable when the source provides a single-pixel input and the panel requires a scaled LVDS output rather than a separate scaler followed by a discrete transmitter. The main design consideration is that this is a display-interface device with one transmit direction and no LVDS receiver. It cannot replace a bidirectional LVDS transceiver, and firmware must configure the host link, panel timing, and scaling ratio correctly. Use the pin-description table and application circuit in the manufacturer datasheet when assigning the 128 terminals and the exposed thermal pads. This page brings together the device specifications, package information, application fit, design guidance, and verified sourcing details. It also distinguishes the DS90C2501SLB from generic LVDS drivers and transceivers so design teams can determine whether its integrated scaler, single-pixel input, and 128-terminal footprint match the intended display architecture.
DS90C363AMTD - 18-Bit 65 MHz LVDS Transmitter | Texas Instruments
The Texas Instruments DS90C363AMTD is a 3.3 V programmable LVDS transmitter for 18-bit Flat Panel Display Link interfaces, operating at up to 65 MHz and using a 48-pin TSSOP package. It provides three LVDS data drivers and 21 receiver-oriented transceiver positions in a single display-interface device. Its LVDS output supports data rates up to 612.5 Mbps per channel, making it suitable for transferring parallel pixel data over a compact, noise-resistant differential interface. An LVDS transmitter is a high-speed interface IC that converts low-voltage differential signaling into the physical layer used by FPD-Link links. In the technology hierarchy, LVDS is a differential data transmission method, while FPD-Link is an interface protocol commonly used to connect display controllers and flat-panel panels. The DS90C363AMTD belongs to the broader interface IC category and combines parallel display-data handling with balanced, low-voltage differential outputs. This reduces signal-integrity and EMI challenges associated with long interconnects when implemented with correct PCB rules. The principal operating characteristics are a 3 V to 3.6 V supply range, 18-bit parallel data capability, 65 MHz maximum pixel-clock operation, and three LVDS drivers. The device also supports programmable LVDS output characteristics, enabling the transmitter to be adapted to different display-link and termination requirements. It is supplied in a 48-pin TSSOP package intended for tube packing under the AMTD ordering suffix. Technically, the DS90C363AMTD is designed to provide backward-compatible LVDS signaling for FPD-Link panel interfaces while operating from a 3.3 V system rail. The differential outputs use small signal amplitudes to support high data rates while limiting electromagnetic emissions. Clock and data lanes should be routed as controlled-impedance differential pairs, with matching termination and connector geometry maintained between the transmitter and the receiving circuitry. Typical applications include flat-panel LCD controller interfaces, digital display panels, industrial monitors, medical display controllers, and compact embedded display systems. It is particularly useful where an 18-bit parallel pixel bus must be converted into fewer balanced LVDS lines. The 65 MHz operating limit must be checked against the target panel timing, while power sequencing, input-voltage tolerances, and panel-specific initialization requirements must be reviewed before deployment. A critical design consideration is the relationship between data-clock timing and transmission rate. Trace skew between the clock and data channels, inadequate output-termination networks, and long unmatched stubs can impair LVDS eye quality. The transmitter should be placed near the source connector or display interface, and the datasheet timing and test-circuit recommendations should govern component placement and PCB stack-up. This product page combines the manufacturer identification, electrical and package characteristics, interface application guidance, comparison criteria, and practical PCB considerations needed to evaluate the DS90C363AMTD as the transmitter for a 3.3 V FPD-Link display system.

An LVDS transmitter is a specialized interface IC that converts low-voltage digital logic signals into differential data pairs. Differential signaling belongs to the LVDS interface hierarchy and is commonly used for point-to-point links where low voltage, low power, and resistance to common-mode noise are important. In an FPD link, the transmitter works with a corresponding receiver, reducing signal-integrity demands compared with driving panel inputs directly through single-ended CMOS/TTL lines. The DS90C363BMT operates from a +3.3 V supply and supports a maximum link clock frequency of 65 MHz. Its 21-bit parallel input arrangement accommodates an 18-bit flat panel data path together with associated control or synchronization signals. The transmitter provides three LVDS outputs, enabling parallel data to be transferred efficiently over a reduced number of differential channels. The DS90C363B belongs to a family of National Semiconductor-origin display interface devices that was later represented under Texas Instruments. Verified comparison information identifies the DS90C363B as backward compatible and pin-for-pin compatible with the DS90C363, DS90C363A, and DS90CF363 families. The DS90C365A is also identified as pin-to-pin compatible with the DS90C363 and DS90C363A. Typical uses include flat-panel LCD controller interfaces, digital display panels, industrial HMI systems, medical imaging displays, test equipment, and other systems that connect parallel video logic to an LVDS panel. The 48-TSSOP package supports conventional surface-mount PCB assembly, while the 3.3 V supply operation aligns with modern embedded display electronics. When designing the transmitter interface, preserve the LVDS differential pair routing recommended by the device documentation, use matched-length routing where appropriate, and provide a controlled reference plane between signal pairs. Confirm capacitor selection, reset or power-down behavior, clock timing, and panel compatibility against the current manufacturer datasheet before releasing a production layout. This product page combines verified manufacturer and distributor information, documented family drop-in relationships, packaging details, pricing, and application-oriented design guidance.

DS90C363BMTX - 3.3V 18-Bit FPD-Link LVDS Transmitter | TI
The Texas Instruments DS90C363BMTX is a +3.3V programmable LVDS transmitter for 18-bit Flat Panel Display (FPD) Link applications, operating up to 65 MHz clock frequency. Housed in a 48-pin TSSOP (MTD) package, it serializes 18 bits of parallel RGB data plus control signals into four LVDS data streams plus one LVDS clock, providing up to 1.3 Gbps throughput and 170 Megabytes/sec bandwidth. A Flat Panel Display Link (FPD-Link) transmitter is a serializer IC that converts wide parallel CMOS/TTL buses (such as RGB video, control signals, and synchronization data) into a small number of high-speed differential LVDS pairs for transmission over a flexible flat cable or PCB trace to a remote display. FPD-Link sits within the hierarchy: serializer/deserializer (SerDes) -> LVDS interface -> display interface IC -> power management IC -> semiconductor. This category enables long-distance, low-EMI video distribution in space-constrained notebooks, monitors, and industrial displays. Key specifications include 345 mV typical LVDS swing, compatibility with the TIA/EIA-644 LVDS standard, integrated PLL requiring no external components, narrow bus that reduces cable size and cost, transmit power-down mode consuming less than 37 uW (typical), and 40 percent less power dissipation than BiCMOS alternatives. The DS90C363B supports VGA, SVGA, XGA and dual-pixel SXGA, with programmable clock edge and selectable data mapping. The device uses an internal PLL to multiply the input clock up to the required LVDS line rate, then performs 7:1 serialization per LVDS data channel using an LVDS current-mode driver. This minimizes pin count on the system side and dramatically reduces EMI compared with wide parallel TTL buses, making it ideal for notebook LCD panels, automotive instrument clusters, and industrial HMI displays. Typical applications include notebook computer LCD panels, flat panel monitors, industrial HMI displays, automotive infotainment screens, and digital signage. The narrow LVDS bus significantly reduces cable and connector cost versus traditional TTL routing. When designing with the DS90C363B, pay close attention to controlled-impedance routing of the four LVDS data pairs plus the LVDS clock pair; use 100 ohm differential impedance and keep skew tight to preserve data and clock alignment at the receiver. This page synthesizes distributor pricing, drop-in alternatives, application notes, and practical PCB layout guidance not aggregated on any single distributor or manufacturer page.

The device provides three LVDS data drivers for transferring display data over a low-voltage differential signaling link, supporting a throughput of up to 1300 Mbps per the published comparison data. Its nominal 3 V to 3.6 V supply range allows integration with 3.3 V display-processing systems. An LVDS transmitter is a display-interface IC that converts low-voltage digital data into balanced differential signals. In the signal-chain hierarchy, the DS90C363 belongs to interface ICs, display link controllers, and ultimately semiconductor-based display communication systems. LVDS links use differential signaling to reduce voltage noise, ground-referenced return current, and electromagnetic-interference sensitivity compared with single-ended parallel display interfaces. The 18-bit architecture supports parallel display data while the differential link consolidates that data into fewer signal pairs. Programmable operation provides configuration flexibility for supported display timing and link arrangements. The 65 MHz operating specification, 1300 Mbps data rate, and 3.3 V supply establish the principal performance envelope of this transmitter. The DS90C363 is associated with the DS90C363 and DS90CF364 3.3 V programmable 18-bit FPD-Link family. Its 48-pin TSSOP arrangement provides a conventional surface-mount implementation for industrial display, digital signage, test-and-measurement equipment, and embedded visualization systems where LVDS link integrity is required. The DS90C363MTD is identified as NRND in the available cross-reference information. Designers should therefore check current Texas Instruments lifecycle, qualification, and availability notices before starting a new production design. Although inventory is reported by a distributor, lifecycle status rather than temporary stock availability should determine whether the device is appropriate for a new BOM. For a new design requiring active lifecycle status, verify whether a related DS90C365A-family transmitter provides an appropriate supported alternative. For an existing DS90C363MTD assembly, preserve the original 48-pin TSSOP footprint, confirm the exact clocking and power-down behavior, and validate the replacement against the display timing, connector, and cable requirements. This page consolidates the verified manufacturer description, distributor inventory and pricing, lifecycle information, and cross-reference results while explicitly identifying unavailable pin-level and electrical details. It also provides application guidance and compares the verified replacement candidates without treating unreported electrical values as guaranteed specifications.
DS90C365AMT - 3.3V 18-Bit LVDS FPD Transmitter | TI
The Texas Instruments DS90C365AMT is a +3.3 V programmable 18-bit Flat Panel Display Link transmitter that converts 21 bits of LVCMOS/LVTTL data into four LVDS differential data streams. It supports a 3 V to 3.6 V supply, an 87.5 MHz pixel clock, an aggregate data rate of 1.785 Gbps, and a 48-TSSOP package. The interface is designed for high-speed point-to-point connections between display timing controllers and LVDS panel receivers. A Flat Panel Display Link transmitter is a display-interface IC that converts parallel logic signals into low-voltage differential signaling. This conversion reduces signal amplitude, supports clock-rate multiplication, and carries pixel and control data across a compact differential link. The DS90C365A family belongs to the broader category of display serializers and interface transceivers, placing it within the semiconductor and display-interface hierarchy. The DS90C365AMT accepts 18-bit display data together with associated control and clock information and serializes the information into four LVDS lanes. Its programmable operation supports link configuration across different display architectures. The 87.5 MHz link frequency and 1.785 Gbps data capability make the device applicable to flat-panel displays, industrial LCD panels, digital signage, and other multi-pixel parallel-to-LVDS interfaces. The DS90C365A incorporates a phase-locked loop that supports the high-speed serialization function. Because this is a transmitter-only device, it requires a compatible LVDS receiver at the other end of the link. The 48-TSSOP package provides 48 external terminals and is suitable for conventional surface-mount PCB assembly. Tube packaging is identified for the DS90C365AMT ordering variant in distributor search data. Typical implementations connect a display timing controller or graphics source to an LVDS display panel. The transmitter accepts parallel pixels and control signals, then sends four differential lanes carrying serialized data and embedded clock information. The receiver determines the supported display timing and must be electrically compatible with the transmitter output. This arrangement is useful where a compact LVDS interface is required instead of a direct parallel interface across the full board or cable distance. Designers should verify LVDS trace impedance, differential pair geometry, connector or panel requirements, receiver compatibility, and the power-supply decoupling network against the manufacturer datasheet. The stated 3 V to 3.6 V operating supply leaves little tolerance for supply overshoot, so routing and load behavior must be controlled. Pin assignments and unused-terminal details should be taken directly from the manufacturer documentation before PCB routing. This page consolidates the verified manufacturer and distributor information for DS90C365AMT, identifies documented pin-compatible family replacements, and provides application guidance, comparison criteria, and design considerations. It also distinguishes verified performance figures from parameters that require confirmation from the complete manufacturer datasheet.

The Texas Instruments DS90C365AMTX is a +3.3 V programmable LVDS transmitter for an 18-bit Flat Panel Display link, operating at up to 87.5 MHz with four LVDS data streams in a 48-pin TSSOP package. The device provides the high-speed differential signaling required to transfer pixel data between a display controller and panel interface while accepting LVCMOS or LVTTL source signals. An LVDS transmitter is a high-speed interface IC that converts parallel logic data into low-voltage differential pairs. LVDS belongs to the broader interface-IC hierarchy and supports reliable point-to-point links over longer PCB or cable distances than ordinary single-ended CMOS because its differential signaling improves noise immunity. In a Flat Panel Display Link, the transmitter serializes parallel display data into four differential channels that are paired with a suitable LVDS receiver at the display endpoint. The DS90C365A family supports an 87.5 MHz link and provides programmable operation for display-panel interface requirements. Its +3.3 V supply operation, four LVDS outputs and 21-bit internal input conversion support an 18-bit Flat Panel Display payload with associated clock and control signaling. The device also supports flexible data and clock arrangements, helping panel designers adapt one controller design to different display timing and interface conventions. The DS90C365A is a pin-to-pin replacement for DS90C363, DS90C363A and DS90C365 according to Texas Instruments. It includes improvements intended for display links while avoiding the no-EN pin of earlier devices. No special startup sequence is required between the clock, data and power-down inputs, allowing source signals to be applied before or after device power-up. That characteristic simplifies system sequencing and reduces controller reset complexity. Typical applications include flat-panel LCD monitors, industrial panel displays, medical-display controllers, automotive navigation displays, digital signage and other LVDS display interfaces. The transmitter is most appropriate when a host processor or display controller must serialize parallel pixel data into compact differential channels without relying on a higher-voltage source-synchronous interface. The primary design considerations are LVDS trace impedance, connector and cable compatibility, receiver selection, panel timing and power sequencing. The data and clock inputs must be driven by CMOS-compatible logic, while the four differential outputs require matched routing and the receiver or panel input must support the corresponding data and clock channel arrangement. Use the Texas Instruments datasheet pin-description and typical-application tables to assign every signal. This product page organizes the DS90C365AMTX specifications, verified sourcing information, pin-compatible family alternatives, application guidance and design notes into one engineering reference. It also distinguishes confirmed manufacturer characteristics from parameters that require verification against the latest device documentation before a board is released for production.
