DP8392CV-1 - Coaxial Transceiver Interface (CTI) | Texas Instruments
The Texas Instruments DP8392CV-1 is a Coaxial Transceiver Interface (CTI) for IEEE 802.3 Ethernet networks, integrating a 10BASE2/10BASE5 coaxial line driver and receiver with collision detection and a built-in jabber timer in a 28-pin PLCC (V28A) surface-mount package. The device operates as part of the classic DP8390/DP8391/DP8392 chipset, providing the physical-layer interface between a DTE and a coaxial cable segment with on-chip transmit/receive switching and heart-beat generation. A Coaxial Transceiver Interface (CTI) is a type of network transceiver IC that connects a Medium Access Controller (MAC) to a coaxial Ethernet bus, performing electrical line driving, signal recovery, collision detection (signal-quality error pulse generation), and jabber fault isolation. CTIs are a subset of physical-layer (PHY) transceivers that sit between the MAC block and the cable medium, and are descendants of early 10 Mb/s Ethernet silicon that pre-dated modern twisted-pair PHYs in the OSI model's physical layer of the network stack. Key features of the DP8392CV-1 include a 10 Mb/s Manchester-encoded data rate, a single +5 V supply operation, integrated transmit/receive path switching, integrated SQE (Signal Quality Error) test pulse generation, a built-in jabber timer with automatic transmitter disable after the maximum packet time, and a TTL/CMOS-compatible interface to the DP8390 NIC and DP8391 encoder/decoder devices. The 28-PLCC pinout uses J-bend surface-mount leads and is organized for direct cable-side and digital-side pin groups to simplify PCB layout. The architecture uses a bipolar driver for the coaxial interface with separate transmit and receive amplifiers, a 10 MHz fundamental oscillator with external clock-reference support, and an analog collision-detection comparator that produces the standard heart-beat pulse during inter-packet gaps. The on-chip jabber latch disables the transmitter if a continuous transmit exceeds the packet-time threshold, protecting the coax segment from stuck-node faults. Commercial-grade temperature range (0C to +70C) targets office and lab Ethernet environments. Typical applications include 10BASE2 (Thin Ethernet / Cheapernet) network interface cards, 10BASE5 (Thick Ethernet) AUI-to-coax converter adapters, legacy industrial Ethernet backbones on coax, and embedded systems that require an IEEE 802.3 coax link to communicate with vintage networking equipment or to bridge older industrial fieldbus hardware. The part also sees use in test equipment that emulates a coax segment endpoint. When designing with this device, observe AC termination and DC bias requirements specified in the datasheet typical application - a 1:1 pulse transformer on the Tx/Rx line and external pull-up/pull-down resistors on collision and receive-data lines. Decoupling should keep the +5 V supply near the analog VCC pins with both bulk and 0.1 uF ceramic capacitors to prevent noise from coupling into the receive path.

It provides a 2/2 transceiver arrangement, MAC-interface flexibility through MII, RMII, and RGMII, and diagnostic-tool support for automotive Ethernet designs. The device is supplied in a 6.00 mm × 6.00 mm, 36-pin VQFN package with wettable flanks. An automotive Ethernet PHY is a physical-layer interface integrated circuit that converts digital MAC data into signals suitable for a vehicle network and converts received cable signals back into digital data. It sits between an Ethernet MAC and the twisted-pair medium, providing the physical encoding, signaling, and diagnostic functions required for reliable in-vehicle communication. The DP83TC811R-Q1 family supports MII, RMII, and RGMII MAC interfaces through xMII flexibility. Its IEEE 802.3bw compliance targets 100BASE-T1 automotive Ethernet applications, where low-speed single-pair links are used to reduce wiring complexity while supporting vehicle data and control networks. The manufacturer also describes an integrated Diagnostic Tool Kit and a PRBS frame-generation tool compatible with internal loopbacks for transmit and receive testing without a MAC. The package uses a wettable-flank VQFN construction, which supports inspection of solder joints in automotive electronics assemblies. Its 36-pin package and 6 mm × 6 mm footprint are intended for surface-mount designs. Exact operating voltage, current, timing, temperature, pin names, isolation, and qualification values must be confirmed from the manufacturer datasheet before schematic release or PCB layout approval. Typical design uses include automotive Ethernet gateways, vehicle domain controllers, infotainment systems, telematics units, body controllers, sensor interfaces, and diagnostic test equipment. The MAC-side interface is selected according to the host controller requirements, while the cable-side network is designed according to the applicable 100BASE-T1 wiring and automotive Ethernet implementation constraints. The flexible MAC interface helps reduce platform duplication across different host-controller configurations. A key design consideration is validating the complete interface chain, including MAC timing, cable termination, common-mode components, isolation strategy, connector selection, and automotive EMC requirements. This page combines verified manufacturer and distributor information with explicit data gaps; it does not infer electrical specifications that are absent from the supplied source data. Engineers should use the official DP83TC811R-Q1 datasheet and product page for final component selection and implementation.
DP83TC812SRHARQ1 - 100BASE-T1 Auto Ethernet PHY | Texas Instruments
The Texas Instruments DP83TC812SRHARQ1 is an AEC-Q100 qualified, TC-10 compliant 100BASE-T1 automotive Ethernet PHY transceiver housed in a 36-pin VQFN (RHA) 6x6 mm package with RGMII and SGMII MAC interfaces. The device delivers 100 Mbps over a single twisted pair using proprietary 100BASE-T1 IEEE 802.3bw physical layer technology, supporting full-duplex and half-duplex operation in harsh automotive environments. An automotive Ethernet PHY is a physical layer transceiver that converts digital MAC data into differential pulse-shaped signals transmitted across an unshielded single twisted-pair (UTP) cable, while simultaneously decoding received signals back into digital data. The DP83TC812S-Q1 family sits within the broader in-vehicle networking hierarchy: PHY -> transceiver -> Ethernet switch -> ECU/gateway -> automotive zonal architecture, replacing legacy CAN, FlexRay, and LIN buses in ADAS, infotainment, and chassis domains. Key features of the DP83TC812SRHARQ1 include integrated TC-10 wake/sleep state machine for power-managed automotive networks, low-power sleep current below the TC-10 specification, RGMII and SGMII MAC interface options for flexible SoC connectivity, and on-chip diagnostics including cable diagnostics, signal quality indicator, and IEEE 1588 SFD timestamping. The 36-VQFN package with exposed thermal pad provides a robust thermally efficient surface-mount footprint qualified to AEC-Q100 Grade 1 (-40C to +125C). Architecturally, the DP83TC812SRHARQ1 uses a DSP-based echo-cancelling receiver with adaptive equalization to support automotive cable lengths up to 15 m of UTP. Internal LDOs generate analog and digital rails from a single 1.8V or 3.3V supply, while the MAC interface, MDI, and management (MDIO/MDC) signals operate from a separate I/O domain, simplifying multi-voltage SoC integration. Typical applications include automotive advanced driver assistance systems (ADAS) camera and radar links, in-vehicle infotainment (IVI) backbones, body and chassis domain controllers, zonal Ethernet gateways, and ECU-to-ECU bridged networks. The TC-10 compliance enables partial networking where unused PHYs can sleep while the rest of the network remains active, reducing vehicle quiescent current. When designing with the DP83TC812SRHARQ1, ensure the MDI differential pair is routed as a 100-ohm differential transmission line with ground-referenced return path and that the supply decoupling network follows the TI reference layout. The device supports both RGMII (1.8V/2.5V/3.3V) and SGMII, allowing pin-compatible upgrades from older 100BASE-TX designs with the same 36-VQFN footprint. This page synthesizes distributor pricing, drop-in VQFN-36 alternatives, application recommendations, and practical design notes not found in the manufacturer datasheet, optimized for engineers evaluating automotive Ethernet PHYs.
DP83TC814R-Q1 - 100BASE-T1 Auto Ethernet PHY | TI
The Texas Instruments DP83TC814R-Q1 is a low-power 100BASE-T1 automotive Ethernet physical layer (PHY) transceiver, IEEE 802.3bw compliant and AEC-Q100 qualified, housed in a 36-pin VQFN package measuring 6.00 mm x 6.00 mm with wettable-flank leads. The R-suffix version omits TC10 sleep/wake support, differentiating it from the DP83TC814S-Q1 variant. An Ethernet PHY (physical layer device) is the interface IC that converts digital MAC frames into signals transmitted over a physical medium. In the Ethernet IC hierarchy - PHY transceiver -> Ethernet controller -> network interface -> automotive E/E architecture - the PHY is the final analog stage that determines link robustness, power draw, and EMC behavior. 100BASE-T1 (formerly BroadR-Reach) transmits 100 Mbps full-duplex over a single unshielded twisted pair, halving cabling weight versus conventional 100BASE-TX. Key features include a flexible MAC interface whose I/O supply (VDDMAC) is configurable to 1.8 V, 2.5 V, or 3.3 V, easing direct connection to a wide range of automotive microcontrollers without level shifters. The device supports full and half duplex operation with RMII media access, integrates TI's diagnostic tool kit for real-time link monitoring, and delivers low-power modes essential for network-managed ECU sleep strategies. According to the DP83TC814x-Q1 datasheet, the die family shares a common footprint strategy across speed grades. A major engineering benefit is footprint unification: the device is pin-2-pin compatible with the DP83TG720 (1000BASE-T1) and form-factor compatible with DP83TC811 and DP83TC812, so a single PCB layout can be reused across DP83TC811, DP83TC812, DP83TC814, and DP83TG720 designs. This lets automotive Tier-1s qualify one board platform for 100 Mbps and 1 Gbps in-vehicle networking variants. Typical applications include camera and sensor data links in ADAS systems, gateway ECUs bridging CAN and Ethernet domains, infotainment backbone nodes, and domain/zonal controller interconnects in modern vehicle networks. When designing with this part, follow TI's reference design guidance for the single-pair MDI termination and magnetics network, and verify EMC performance on the target harness, since automotive 100BASE-T1 compliance depends heavily on layout and common-mode treatment. This page adds value beyond the datasheet by synthesizing distributor availability, drop-in alternatives, and practical design notes in one place. Pricing shown is as of 2026-10-19.
DP83TC815-Q1 - 100Base-T1 Automotive Ethernet PHY | Texas Instruments
The Texas Instruments DP83TC815-Q1 is an IEEE 802.3bw and Open Alliance (OA) compliant automotive-qualified 100Base-T1 Ethernet physical layer transceiver delivering full PHY functionality over a single unshielded or shielded twisted pair, housed in a 36-pin VQFN (6x6 mm) package. The device supports RGMII, SGMII, and xMII interface flexibility with hardware time-stamping per IEEE 802.1AS / IEEE 1588v2. It targets 100 Mbps automotive Ethernet networks requiring precise time synchronization. An automotive Ethernet PHY (Physical Layer transceiver) is an interface IC that converts digital MAC-side data into differentially-encoded signaling for transmission over copper twisted-pair cabling. Within the OSI model, it occupies Layer 1, sitting between the MAC controller (or switch) and the physical medium. The 100Base-T1 (IEEE 802.3bw) variant uses full-duplex transmission over a single twisted pair with PAM-3 / binary encoding and EMC-friendly spectral shaping, replacing legacy CAN and FlexRay backbones in zonal automotive architectures. The DP83TC815-Q1 belongs to the broader category of automotive PHYs that bridge Ethernet PHYs -> wireline transceivers -> interface ICs -> integrated circuits. Key features include compliance with IEEE 802.3bw 100Base-T1 and the OPEN Alliance TC-1/TC-10 specifications, integrated IEEE 802.1AS / IEEE 1588v2 hardware time-stamping for sub-microsecond synchronization across ADAS sensors, OA TC-10 low-power sleep with wake forwarding, and AEC-Q100 qualification for automotive temperature grades. The single twisted-pair interface dramatically reduces wiring harness weight versus traditional 100Base-TX (which requires two pairs). The architecture combines an analog front-end with DSP-based echo and crosstalk cancellation, a precision PLL, and a digital interface controller. Hardware time-stamping on both transmit and receive paths ensures deterministic latency for time-sensitive applications such as radar sensor fusion, deterministic Ethernet, and synchronized distributed camera networks. Typical applications include automotive ADAS sensor Ethernet links, body and zonal ECU networking, rear-view and surround-view camera systems, in-vehicle infotainment backbones, and industrial 100Base-T1 links requiring the same precision timing. Designers select this part when they need an automotive-grade 100 Mbps single-pair Ethernet PHY with hardware time-stamping and the OPEN Alliance TC-10 sleep/wake feature for power-constrained modules. When designing with this device, ensure the MDI network matches the OPEN Alliance TC-1 channel specification and place the 1:1 termination and common-mode choke close to the MDI pins. The TC-10 sleep entry/exit sequence requires careful MAC-side coordination to honor wake-forward timing budgets; this part is intended as a drop-in PHY replacement for other TI 36-pin VQFN 100Base-T1 designs. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, including TSN configuration guidance, xMII selection trade-offs, and OPEN Alliance TC-10 power-state sequencing.

The Texas Instruments DP83TG720RWRHATQ1 is an IEEE 802.3bp and Open Alliance compliant automotive Ethernet physical layer transceiver (PHY) that provides all physical layer functions needed to transmit and receive data over unshielded or shielded single twisted-pair cables, supporting 1000BASE-T1 in a 36-pin VQFN (6x6) package. It operates from a 1.8V/2.5V/3.3V supply, integrates an RGMII MAC interface, and is AEC-Q100 qualified for automotive grade 1 environments. The device supports both full-duplex and half-duplex operation over a single twisted pair, delivering Gigabit-class Ethernet in automotive zonal architectures. What is an automotive Ethernet PHY? An automotive Ethernet PHY is a physical layer transceiver that converts digital MAC-layer data into analog signals suitable for transmission over copper cabling inside a vehicle. It sits between the Media Access Controller (MAC) and the MDI connector, encoding/decoding bits and handling line-side equalization, echo cancellation, and link training. As part of the broader Ethernet PHY category (Ethernet PHY -> transceiver -> interface IC -> semiconductor), automotive Ethernet PHYs follow IEEE 802.3bp (1000BASE-T1) and Open Alliance specifications designed for electromagnetic compatibility and single-pair robustness inside vehicles. Key features of the DP83TG720RWRHATQ1 include 1000 Mbps line-side throughput, RGMII host interface, integrated 100BASE-T1 legacy support via front-pin compatibility with TI's lower-speed PHY family, Open Alliance interop compliance, and operation from -40C to +125C. The device provides MAC-side loopback, diagnostic PRBS patterns, and cable diagnostics to support field troubleshooting. The 6x6 mm VQFN-36 package with exposed pad supports single-sided PCB routing for compact automotive modules. The DP83TG720 uses DSP-based adaptive equalization and echo cancellation tuned for the harsh automotive environment (PVT variation, motors, ignition noise). The PHY manages wake/sleep signaling for Partial Networking and operates from a 1.8V digital core with separate analog supplies for isolation from noise on the MDI line. Front-pin compatibility with the 100BASE-T1 DP83TG720S-Q1 enables one PCB layout to support both 100 Mb and 1 Gb automotive Ethernet. Typical applications include advanced driver-assistance systems (ADAS) sensor fusion, in-vehicle networking gateways, surround-view and 4D radar data aggregation, automotive zonal ECUs, and telematics/central compute modules. The 1000BASE-T1 link removes the need for legacy automotive buses (CAN, FlexRay) where high bandwidth is required. When designing with this PHY, ensure proper MDI line protection and common-mode chokes are used per application note SNLA244, and follow the DP83TG720 reference schematic for the 1.8V supply decoupling arrangement.

DS10BR150TSD/NOPB - 1.0 Gbps LVDS Buffer/Repeater | TI
The Texas Instruments DS10BR150TSD/NOPB is a single-channel 1.0 Gbps LVDS buffer/repeater optimized for high-speed signal transmission over lossy FR-4 printed circuit board backplanes and balanced cables. Housed in an 8-pin WSON (NGQ) 3x3 mm package, it features fully differential signal paths that ensure exceptional signal integrity and noise immunity, with 39 ps typical propagation delay and 21 mA supply current. An LVDS (Low-Voltage Differential Signaling) buffer/repeater is a signal-conditioning interface IC that regenerates a high-speed differential data path whose amplitude and edge rate have been degraded by PCB trace loss, connector crosstalk, or cable attenuation. The DS10BR150 belongs to the LVDS interface category, within the broader interface IC and high-speed signal-conditioning hierarchy used in networking, telecom, and backplane data links where 100 Ω differential impedance and low jitter are mandatory. Key features include a wide input common-mode voltage allowing acceptance of LVDS, CML, and LVPECL input levels with LVDS-compliant output levels. The device operates from a single 3.3 V supply, supports data rates from DC up to 1.0 Gbps, and provides a power-down pin for standby current reduction. Industrial temperature range of -40°C to +85°C and a low-jitter design make it suited for serial-data distribution in systems where eye-margin preservation across long trace runs is critical. The DS10BR150 uses a fully differential current-mode architecture with internal termination and adjustable receiver equalization, providing a typical propagation delay of 39 ps and ultra-low pulse-skew-generate of 7 ps. The low-jitter characteristic preserves transmit eye-mask compliance across FR-4 backplanes with insertion loss that would otherwise close the eye at GbE and FibreChannel link speeds. Integrated fail-safe biasing ensures a deterministic output when the input is open, shorted, or undriven. Typical applications include FR-4 backplane repeater links between line cards and switch fabrics in networking switches and routers, clock and data distribution in telecom equipment, LVDS extension in test-and-measurement instrumentation, and SATA / FibreChannel signal fan-out in storage area network (SAN) cards. The wide input common-mode range also makes it useful for level-translation between CML/LVPECL drivers and LVDS receivers on mixed-logic boards. When designing with this device, place 100 nF decoupling capacitors as close as possible to the VCC pin and use a continuous ground reference under the WSON exposed pad (EP) to control thermal resistance and provide a low-impedance return path. Maintain 100 Ω differential impedance on input and output traces, route TX/RX pairs length-matched within 5 mil, and avoid right-angle bends to preserve the 1 Gbps eye.

DS10BR254TSQ/NOPB - 1.5Gbps 1:4 LVDS Repeater | TI
The Texas Instruments DS10BR254TSQ/NOPB is a 1.5 Gbps 1:4 LVDS repeater with a 2:1 multiplexed input stage, a 440 ps propagation delay and 135 mA supply current, housed in a 40-pin WQFN (RTA) 6x6 mm package with exposed pad. The /NOPB suffix denotes a no-Pb, RoHS-compliant manufacturing flow. An LVDS (Low-Voltage Differential Signaling) repeater, also called a buffer or fanout buffer, is an interface IC that regenerates high-speed differential signals to restore signal integrity over lossy media. In the signal-chain hierarchy it sits between a driver (SoC, FPGA, ASIC) and multiple receivers, extending reach across FR-4 backplanes and balanced-impedance cables while isolating loads that would otherwise degrade edge rates. Key features include a 1.5 Gbps maximum data rate per LVDS channel, a 2-input multiplexer with an external select pin that supports redundant-path or source-switching architectures, four identical fanout outputs that regenerate each input pair with full LVDS swing, and a loss-of-signal (LOS) detection circuit. Fully differential signal paths deliver exceptional noise immunity, while the compact WQFN-40 package with thermal pad enables dense backplane card designs. Architecturally, the device contains two differential input pairs, a low-skew mux, and four parallel low-jitter output drivers. Propagation delay of 440 ps and matched internal channel lengths keep output-to-output skew tight for clock and data distribution. The 1.7 pF input capacitance minimizes loading on the source, and the 3.0 V nominal supply (3.0 V to 3.6 V range) suits standard 3.3 V rails. Typical applications include FR-4 backplane clock and data distribution, redundant bus multiplexing in telecom and networking line cards, high-speed signal fanout from FPGAs or ASICs in test and measurement instrumentation, and long-reach LVDS links over balanced cables. Design consideration: maintain 100-ohm controlled-differential impedance on all LVDS traces, keep the mux select pin stable during operation, and leverage the LOS output for fault reporting in redundant architectures. The exposed pad must be soldered to a grounded copper pour for thermal and return-path performance.

DS15BR400TVS/NOPB - 4-Ch LVDS Buffer 2Gbps TQFP-48 | Texas Instruments
The Texas Instruments DS15BR400TVS/NOPB is a 4-channel LVDS buffer/repeater (ReDriver) supporting data rates up to 2 Gbps per channel, operating from a 3.0 V to 3.6 V supply with a typical supply current of 215 mA, housed in a 48-pin TQFP (PFB) package measuring 7 x 7 mm. An LVDS buffer/repeater is a signal-conditioning interface IC that sits in the middle of a high-speed differential data path. It receives degraded low-voltage differential signaling (LVDS) or Bus LVDS waveforms, regenerates clean logic levels, and re-transmits them, restoring signal integrity over lossy media. In the system hierarchy, it belongs to the signal buffer/repeater class of interface ICs, bridging serializers, deserializers, and backplanes in high-speed digital systems. Key differentiating features include pre-emphasis that overcomes intersymbol interference (ISI) jitter effects from lossy backplanes and cables, a flow-through pinout that simplifies board layout and minimizes internal device jitter, and compatibility with LVDS and Bus LVDS signal levels such as those used by TI 10-, 16-, and 18-bit serializers and deserializers (SerDes). Architecturally, the DS15BR400 uses high-speed differential input buffers followed by output drivers with selectable pre-emphasis, keeping the internal data path short and symmetric. This low-jitter design preserves eye opening at 2 Gbps, which is critical for bit-error-rate targets in multi-gigabit links. The NOPB suffix denotes a lead-free, RoHS-compliant finish. Typical applications include rack-card backplane interconnects, point-to-point cable driver and receiver links, chassis-to-chassis high-speed data distribution, and buffering of SerDes links in industrial, medical imaging, and telecom equipment where signals must traverse long lossy traces or cables. A key design consideration: pre-emphasis increases output swing and therefore power dissipation, so apply only the level needed for the channel loss; excessive pre-emphasis can degrade signal margin at the far end. Verify supply decoupling with low-ESR ceramics close to each VCC pin.

DS160PR410RNQR - 4-Ch PCIe Gen-4 Linear Redriver | Texas Instruments
The Texas Instruments DS160PR410RNQR is a quad-channel low-power, high-performance linear repeater/redriver designed to support PCI Express (PCIe) Generation 1.0, 2.0, 3.0 and 4.0 in a 40-pin WQFN (RNQ) 6x4 mm package with exposed thermal pad. The device operates up to 16 Gbps per lane for PCIe 4.0 and up to 25 Gbps for protocol-agnostic interfaces including Ultra Path Interface (UPI) 2.0. A redriver is a signal-conditioning device that sits between a transmitter and receiver on a high-speed serial link to compensate for channel loss. It uses continuous-time linear equalizers (CTLE) to apply frequency-dependent gain that restores the high-frequency components attenuated by the PCB trace, connector, and cable. The DS160PR410's CTLE boosts up to 18 dB at 8 GHz, which extends channel reach beyond what a passive link budget would normally allow. The device also includes automatic receiver detection tailored to PCIe use cases, allowing seamless insertion on a powered link. Key features of the DS160PR410RNQR include CTLE boost up to 18 dB at 8 GHz, automatic receiver detection for PCIe, integrated termination, individual channel enable/disable via I2C or pin strap, low latency suitable for forward and reverse direction signaling, and 3.3 V single-supply operation. The device is protocol agnostic, meaning it can be repurposed for any AC-coupled, NRZ differential interface up to 25 Gbps without protocol-specific state machines. The architecture uses a linear equalizer at each input followed by a limiting or linear output driver. Unlike retimers, redrivers do not require clock-data recovery (CDR) and do not add protocol latency, making them ideal for PCIe-compliant systems where every nanosecond of added latency must be accounted for in link training. The DS160PR410 supports both linear and limiting modes, giving designers flexibility between preserving multi-level eye characteristics or maximizing output swing. Typical applications include server and workstation motherboards, NVMe SSD riser cards, backplanes, and riser cards that need to recover PCIe signal integrity across long trace routes or through connectors. Industrial and embedded computing platforms with PCIe over cable also benefit. Because the device is protocol agnostic, it can be used for UPI 2.0, SATA, SAS, and other AC-coupled NRZ interfaces up to 25 Gbps. When designing with the DS160PR410RNQR, AC-coupling capacitors must be placed on the upstream transmit side of each redriver channel. The device supports SMBus/I2C control for fine-grained CTLE adjustment, or pin-strap configuration for simple deployment. Layout should keep high-speed differential traces length-matched within the channel and use 85 ohm differential impedance. Refer to the manufacturer datasheet for full register map and recommended PCB footprint.

DS160PR410RNQT - 4-Ch PCIe Gen-4 Linear Redriver, 25 Gbps, 40-WQFN | TI
The Texas Instruments DS160PR410RNQT is a four-channel, low-power, high-performance linear repeater/redriver designed to support PCI Express (PCIe) Generation 1.0, 2.0, 3.0, and 4.0, with protocol-agnostic operation up to 25 Gbps including Ultra Path Interface (UPI) 2.0 and DisplayPort. The part is housed in a 40-pin WQFN (RNQ) 6x4 mm package and integrates four CTLE-equipped receivers that can boost high-frequency loss by up to 18 dB at 8 GHz. A linear redriver (also called a linear repeater or signal conditioner) is a protocol-agnostic high-speed interface IC placed between a transmitter and a receiver to restore signal amplitude and edge rate after channel loss. It sits in the signal-path hierarchy between the physical medium (PCB traces, connectors, cables) and the PHY/SerDes, complementing retimers (which include a CDR and re-clock) by offering lower latency and lower power at the cost of no jitter cleaning. Key features include automatic receiver detection for PCIe use cases, programmable CTLE equalization up to 18 dB at 8 GHz to extend channel reach, integrated termination, low additive jitter, and per-channel equalizer adjustment through pin-strap or SMBus/I2C control. The device supports AC-coupled transmitter common-mode voltage, low stand-by current, and an operating temperature range of -40 C to +85 C. The DS160PR410 uses a continuous-time linear equalizer architecture on each receive path to compensate for frequency-dependent loss from FR4 PCB traces, long cables, and connector crosstalk. Because the redriver is linear (not a retimer), the part adds minimal latency (typically <100 ps per channel) and preserves TX de-emphasis / RX CTLE training handshakes, allowing seamless insertion in PCIe link training without protocol glue logic. Typical applications include server and workstation motherboards (CPU-to-PCIe slot signal conditioning), PCIe riser cards, external PCIe enclosures, storage controllers (NVMe SSD backplanes), accelerator cards (GPU/AI PCIe Gen-4 add-in cards), and embedded platforms that need loss compensation across long PCB routes or backplanes. When laying out a board, place the redriver as close as possible to the lossy element (connector or long trace) and provide a continuous reference-plane ground beneath the WQFN-40 exposed pad for both thermal dissipation and return-path integrity. Decouple each VCC pin with a 0.1 uF X7R cap and a 4.7 uF bulk capacitor to keep the internal CTLE bias network stable.
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.
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.
DS90C401M - Dual LVDS Driver | Texas Instruments
The Texas Instruments DS90C401M is a dual low-voltage differential-signaling (LVDS) driver optimized for high-data-rate, low-power point-to-point links. The verified source data identifies two differential driver outputs, current-mode operation, minimized short-circuit fault current, low EMI from output swings typically near 340 mV, and an 8-lead small-outline package. It is intended to pair with a DS90C402 receiver to form a complete dual high-speed interface solution. An LVDS driver is a differential-signaling interface IC that transmits information through two conductors carrying complementary signals. The small voltage swing reduces electromagnetic emissions while the differential receiver detects the voltage difference between the conductors. In the broader hierarchy, an LVDS driver belongs to the line-driver and interface-IC category and supports balanced, high-speed communication over printed-circuit-board traces and other suitable point-to-point interconnects. The DS90C401M is specifically described as a dual device for high-data-rate and low-power applications. Its current-mode architecture helps keep power dissipation low even at high frequency and limits fault current during short-circuit conditions. These characteristics are important where data throughput must be maintained without allowing interface noise, excessive power, or fault energy to disrupt the linked circuitry. The manufacturer also presents the DS90C401 and DS90C402 as a complementary chip solution. Typical communication links can place the DS90C401M at the transmitting end and a suitable DS90C402 receiver at the receiving end. Differential routing should preserve the conductor geometry and provide a continuous return path beneath or alongside the pair. Because LVDS performance depends on the complete transmission system, cable length, termination, connector geometry, trace impedance, and receiver characteristics must be evaluated together rather than treating the IC in isolation. A key design consideration is maintaining a low-noise power and ground environment. Decoupling capacitors should be positioned close to the supply and ground pins, while differential traces should be routed as a balanced pair with consistent spacing and minimal stubs. The 8-lead package is suitable for conventional surface-mount assembly, but pin assignments, exposed thermal requirements, and process details should be confirmed from the manufacturer datasheet before layout release. This page consolidates verified manufacturer descriptions, distributor links, and the identified complementary-interface relationship. It also distinguishes confirmed facts from parameters not supplied by the verified data, avoiding unsupported claims while providing an engineering starting point for DS90C401M selection, sourcing, and circuit design.
DS90C401MX - Dual LVDS Driver | Texas Instruments
The Texas Instruments DS90C401MX is a dual Low Voltage Differential Signaling (LVDS) driver optimized for high-data-rate, low-power point-to-point interfaces, with two driver channels in an 8-pin SOIC package. According to the manufacturer datasheet, the device is designed to pair with the DS90C402 receiver, and its current-mode architecture helps maintain low power dissipation at high frequency while minimizing short-circuit fault current. An LVDS driver is a differential-signaling interface device that converts low-voltage logic inputs into balanced differential outputs. Its role within the interface hierarchy is important: LVDS belongs to differential digital interface ICs, which sit below high-speed interface transceivers and support reliable point-to-point data transfer over cables or PCB traces. Differential signaling improves noise immunity by comparing the voltage difference between two conductors rather than relying on a single conductor referenced to ground. The DS90C401MX provides a dual-driver arrangement for systems requiring two independent LVDS transmit channels. Its current-mode operation is specifically highlighted for high-data-rate operation, where the device is intended to limit power dissipation and short-circuit current. The companion DS90C402 receiver is identified by the manufacturer as the matching device in a complete dual high-speed point-to-point interface solution. The verified product information identifies the device as a dual LVDS driver in an 8-SOIC package. Detailed electrical limits, input thresholds, differential output voltage, propagation delay, maximum data rate, supply current, temperature range, and recommended decoupling values are not present in the supplied search excerpts. Those parameters should therefore be confirmed in the official Texas Instruments datasheet before final circuit design or production release. Typical applications include high-speed point-to-point links, industrial control connections, test and measurement equipment, communications equipment, and embedded systems that use LVDS physical signaling. The device can be paired with DS90C402MX-family receivers when the system architecture uses a transmitter and receiver across a balanced connection. Its dual-channel structure can reduce the number of driver packages required when two links share similar electrical and timing requirements. A key design consideration is to preserve the intended point-to-point topology and controlled-impedance routing between the driver and receiver. LVDS traces should be routed as a closely coupled differential pair, with the receiver and transmitter reference-design practices followed from the manufacturer documentation. Do not substitute electrical specifications from a similar interface IC without checking the full timing, voltage, supply, and fault-current requirements. This page synthesizes the verified manufacturer identity, package information, companion-interface relationship, and cross-reference findings for DS90C401MX. It distinguishes documented facts from unprovided technical values so engineers can identify the part efficiently without mistaking incomplete search excerpts for a complete datasheet specification.
DS90C402M - Dual LVDS Receiver, ±100 mV | Texas Instruments
The Texas Instruments DS90C402M is a dual Low Voltage Differential Signaling receiver optimized for high-data-rate, low-power point-to-point interfaces, with two receivers, ±100 mV threshold sensitivity, common-mode noise protection, and an 8-lead SOIC package. It is designed to work with the DS90C401 as part of a dual high-speed interface solution. What is an LVDS receiver? Low Voltage Differential Signaling, or LVDS, is a differential digital interface technology that conveys one bit across two conductors carrying complementary signals. An LVDS receiver detects the voltage difference between those inputs and rejects common-mode noise that appears equally on both conductors. In the broader hierarchy, the DS90C402M is a differential line receiver, interface IC, digital communications component, and semiconductor. The main verified features are its dual-receiver architecture, ±100 mV input threshold sensitivity, and common-mode noise protection. The device is packaged in a PCB space-saving 8-lead small-outline package identified by distributor listings as SOIC. The receiver is intended for high-data-rate and low-power applications, making it suitable for point-to-point links where low voltage, differential signaling, and noise immunity are important. The DS90C401 and DS90C402 form a complementary pair-chip solution for dual high-speed point-to-point communication. Using matched differential routing helps preserve signal integrity and reduces susceptibility to external noise. The receiver’s threshold specification also defines the input signal region it recognizes as a valid differential transition, while common-mode protection helps the interface tolerate noise present on both input conductors. Typical applications include high-speed point-to-point links, low-voltage serial communication, LVDS-compatible backplanes, industrial control links, test equipment interfaces, and embedded systems that use differential digital signaling. The DS90C402M should be selected when the board uses the same eight-pin SOIC footprint and the interface electrical requirements match the verified receiver specifications. The datasheet should be consulted for supply voltage, input common-mode range, propagation delay, and absolute maximum ratings before final design release. For PCB implementation, keep the differential pair impedance controlled and minimize stubs and unnecessary routing length. Provide a continuous reference plane and terminate unused inputs according to the manufacturer’s guidance. Avoid substituting generic differential receivers without checking pin mapping, supply voltage, threshold behavior, and propagation delay. This page consolidates the verified manufacturer and distributor information, distinguishes documented facts from missing data, and provides application and design guidance beyond a basic distributor listing.
DS90C402MX - Dual 155.5Mbps LVDS Receiver | Texas Instruments
The Texas Instruments DS90C402MX is a dual Low Voltage Differential Signaling receiver optimized for high-data-rate, low-power point-to-point links. It receives two differential data streams at up to 155.5 Mbps, provides ±100 mV receiver-threshold sensitivity, and includes common-mode noise protection. The device is packaged in an 8-lead small-outline package identified by the verified distributor data as an 8-SOIC configuration. An LVDS receiver is an interface IC that detects a small differential voltage between two conductors and converts that signal into a compatible digital logic output. This differential method belongs to the broader interface-IC and signal-conditioning hierarchy. Compared with single-ended links, differential reception can improve noise immunity by rejecting common-mode disturbance. The DS90C402MX is intended for one half of a dual high-speed link when paired with the Texas Instruments DS90C401. Key features include two independent LVDS receivers, operation to 155.5 Mbps, ±100 mV threshold sensitivity, and common-mode noise protection. Its low-power design targets systems where receiver power and board area are constrained. The dual architecture consolidates two receive channels into one package, reducing component count compared with two separate single-channel receivers. The exact supply current, input capacitance, propagation delay, output timing, and connector details are not present in the supplied verified data and therefore are not inferred here. The receiver’s differential inputs are intended for point-to-point communication, where a complementary transmitter establishes the proper signal and termination environment. Its common-mode protection is especially relevant when traces share a board with digital or switching circuitry. Engineers must nevertheless preserve the differential geometry recommended by the manufacturer datasheet and control impedance consistently from transmitter through receiver. A receiver alone does not create a compliant LVDS link; the transmitter, cable or PCB transmission medium, termination, connector, and system grounding all affect signal integrity. Typical applications include dual-channel point-to-point backplanes, industrial control links, embedded instrumentation, and compact communications equipment. The DS90C401/DS90C402 pairing supports two coordinated high-speed channels where a single-channel LVDS receiver would require duplicated packages. In data converters or digital processing systems, the receiver can also recover signals arriving from a remote circuit board when the board-level channel has already been characterized. The primary design consideration is preserving LVDS signal integrity through controlled-impedance, tightly coupled routing and correct termination. Review the complete manufacturer datasheet for electrical tables, recommended land patterns, input topology, and timing before release because several detailed values are unavailable in the verified excerpts. For pricing and replacement decisions, do not assume that a functional transceiver or driver is pin compatible; the receiver must match the existing footprint, supply arrangement, and pinout. This page combines the verified manufacturer descriptions, package identification, operating-rate reference, threshold sensitivity, and replacement search results into an engineering-oriented DS90C402MX overview. It distinguishes verified facts from parameters that require the full datasheet and avoids presenting unverified electrical, compliance, lifecycle, or pricing claims as established specifications.
DS90CR216MTDX/NOPB - 3.3V LVDS 21-Bit Channel Link Receiver | TI
The DS90CR216MTDX/NOPB is a 3.3V LVDS (Low-Voltage Differential Signaling) receiver from Texas Instruments that converts three LVDS data streams and one LVDS clock back into 21 bits of parallel LVCMOS data. It is part of the Channel Link chipset, designed for high-speed data transmission over reduced conductor counts. The device operates from a 3.0V to 3.6V supply and supports LVDS clock rates from 20 MHz to 66 MHz, corresponding to data rates up to 1386 Mbps. It is housed in a 48-pin TSSOP package (also referred to as 48-TFSOP) with a 6.10mm width, and is available in tape and reel packaging. What is an LVDS receiver? LVDS (Low-Voltage Differential Signaling) is a high-speed, low-power interface standard used to transmit data over twisted-pair or PCB traces. An LVDS receiver is a specialized interface IC that converts differential LVDS signals back into single-ended CMOS/TTL logic levels. In the hierarchy of interface ICs, an LVDS receiver falls under the category of high-speed serializers/deserializers (SerDes) and is a key component in display interfaces, industrial video links, and automotive infotainment systems. The DS90CR216 is specifically a deserializer that reconstructs parallel data from a serialized LVDS stream. Key features of the DS90CR216MTDX/NOPB include a 21-bit parallel output, rising-edge data strobe, and backward compatibility with existing 5V Channel Link transceivers (DS90CR213/DS90CR214). The device provides substantial cable reduction: a 21-bit wide data bus plus clock typically requires up to 44 conductors in a single-ended parallel interface, but with Channel Link, only 9 conductors (3 data pairs, 1 clock pair, and ground) are needed. This reduces cable size, cost, and EMI. The receiver also features a power-down mode and supports interconnects up to 5 meters depending on cable quality. Technically, the DS90CR216 uses a differential signaling scheme with a typical differential output voltage of 0.45V, ensuring low electromagnetic interference and high noise immunity. The device is designed for point-to-point or multi-drop configurations and includes internal termination for the LVDS inputs. The rising-edge data strobe simplifies timing by aligning data capture with the clock edge, reducing setup/hold requirements. The receiver is specified for the industrial temperature range of -40°C to +85°C, making it suitable for harsh environments. Typical applications include flat panel display interfaces, digital video transmission, industrial machine vision, and automotive camera links. The DS90CR216 is often paired with the DS90CR215 transmitter to form a complete Channel Link solution. When designing with this device, ensure proper PCB layout with controlled impedance traces for the LVDS pairs and place the receiver close to the connector to minimize skew. Also, provide adequate decoupling on the VCC pins with 0.1uF and 10uF capacitors. In summary, the DS90CR216MTDX/NOPB is a robust, high-speed LVDS receiver that simplifies data transmission in space-constrained applications. Its low-voltage operation and reduced conductor count make it an efficient choice for modern digital interfaces.
DS90CR283MTDX/NOPB - 5V LVDS 28-Bit Channel Link Transmitter | TI
The Texas Instruments DS90CR283MTDX/NOPB is a 28-bit Channel Link transmitter that converts 28 bits of CMOS/TTL data into four LVDS (Low Voltage Differential Signaling) data streams, with a phase-locked transmit clock transmitted in parallel. Operating from a 4.75V to 5.25V supply, this device supports data rates up to 66 MHz, delivering a total throughput of 1.848 Gbps. Housed in a 56-pin TSSOP (TFSOP) package, it is designed for high-speed point-to-point data transmission over PCB traces or cables, minimizing EMI and reducing interconnect count. Channel Link is a proprietary interface technology developed by National Semiconductor (now part of Texas Instruments) that serializes parallel data into LVDS pairs. This device belongs to the family of LVDS interface ICs, which are used to transmit high-speed digital data with low power consumption and excellent noise immunity. The DS90CR283MTDX/NOPB is the 5V version of the popular DS90CR285, which operates at 3.3V, making it suitable for legacy 5V logic systems. Key features include a 28:4 data compression ratio, a rising-edge data strobe, and a phase-locked loop (PLL) for clock generation. The transmitter accepts 28 single-ended CMOS/TTL inputs and outputs four LVDS data pairs plus one LVDS clock pair. The device supports a wide input clock range and includes a power-down mode to reduce quiescent current. The TSSOP-56 package offers a compact footprint for space-constrained designs. Technically, the DS90CR283MTDX/NOPB uses a differential signaling scheme with a typical output voltage swing of 350 mV across a 100-ohm termination resistor. The LVDS outputs are current-mode drivers that provide low electromagnetic interference (EMI) and high noise immunity. The PLL ensures that the transmitted clock is aligned with the data, simplifying receiver timing. The device is specified for the commercial temperature range (0°C to 70°C) and is RoHS compliant. Typical applications include flat panel displays, digital video interfaces, and high-speed data links in industrial and consumer electronics. The 5V supply makes it ideal for interfacing with legacy TTL logic. When designing with this device, ensure proper termination of the LVDS lines with 100-ohm resistors and maintain controlled impedance on the PCB to preserve signal integrity.
