It provides all physical-layer functions needed to transmit and receive data over standard twisted-pair copper cables or to connect to an external fiber-optic transceiver through the MII/RGMII/RMII MAC interface. An Ethernet PHY (Physical Layer Device) is the lowest layer of the OSI networking stack and handles the analog signaling, clock recovery, line coding (MLT-3 / PAM), and link-state machine on the cable side, presenting a digital MII/RMII/RGMII bus to the MAC on the host side. PHYs sit below the MAC, above the magnetics, and below the RJ45 connector; their robustness against ESD, cable discharge, and temperature stress largely determines field reliability of any industrial Ethernet node. Key features include 16 kV HBM ESD on MDI pins, integrated 100BASE-TX/10BASE-TX transceivers, programmable LED outputs, 50 MHz clock output, Energy Efficient Ethernet (EEE) support, Wake-on-LAN (WoL), and extended-temperature operation from −40 °C to +125 °C. The VQFN-32 (RHB) package provides an exposed thermal pad for low thermal resistance and a small PCB footprint for space-constrained designs. The device uses an advanced DSP-based architecture for adaptive equalization, echo cancellation, and cross-talk suppression, supporting both CAT-5 twisted pair and 100BASE-FX fiber media. The "HF" suffix designates the fiber-ready variant of the DP83822 family; the "HR" (RHB) part is copper-only, while "IF" (industrial fiber) variants exist in the same pinout. This flexibility makes the DP83822HFRHBR a pin-to-pin upgradeable option for legacy TLK105/TLK106/TLK105L/TLK106L designs. Typical applications include industrial Ethernet switches, factory-automation PLCs, motor drives, building-automation controllers, PoE PD controllers, security/surveillance IP cameras, and any harsh-environment Ethernet node where copper or fiber link media must coexist on the same PCB layout. It is widely used in IEC 61850 substation gateways and PROFINET nodes. Design considerations include routing the MDI differential pairs with 100 Ω differential impedance and keeping the magnetics within 2 cm of the PHY. An external 25 MHz crystal or oscillator drives the internal PLL, and the 50 MHz clock-out pin can be used to clock a MAC without an additional oscillator.

Note also that some pins on the related DP83TG720 are NC, so pin functions must be re-verified when reusing layouts. This page synthesizes verified distributor data, drop-in alternatives, migration guidance from TI E2E forum threads, and practical design notes not found in the manufacturer's short-form datasheet.
DS15BR400TSQ/NOPB - 4-Ch LVDS Buffer 2Gbps | TI
The Texas Instruments DS15BR400TSQ/NOPB is a 4-channel LVDS buffer/repeater with data rates up to 2 Gbps, a 3.0V to 3.6V single supply, and 578 mW typical power consumption, housed in a 32-pin WQFN (RTV) 5x5 mm package with exposed pad. An LVDS (Low-Voltage Differential Signaling) buffer/repeater is an interface IC that regenerates high-speed differential signal streams. Within the signal-chain hierarchy of interface ICs, repeaters sit between a differential line driver and receiver, restoring signal amplitude and timing integrity across lossy interconnects such as backplanes, cables, and connectors where ISI (inter-symbol interference) jitter degrades the eye diagram. Key features include a 2 Gbps per-channel data rate, flow-through pinout that minimizes internal device jitter and simplifies board layout, and pre-emphasis that overcomes ISI jitter effects from lossy backplanes and cables. Propagation delay is typically 1.0 ns with only 3 pF input capacitance, reducing loading on the source driver. The differential inputs interface to LVDS and Bus LVDS signals, such as those on TI 10-, 16-, and 18-bit bus LVDS devices. The device is powered from a single 3.3V supply and consumes 578 mW typical (about 215 mA supply current). It operates over the -40C to +85C industrial temperature range, making it suitable for factory-floor and telecom equipment environments. The space-saving WQFN-32 exposed-pad package aids thermal dissipation and supports high-speed signal routing. Typical applications include backplane signal conditioning in telecom and data communication equipment, point-to-point LVDS link extension across cables and connectors, and clock or data distribution to imaging and display subsystems where jitter must be minimized. When designing with this device, keep inter-pair skew matched on the flow-through routing and use the pre-emphasis setting matched to the length of the lossy channel; excessive pre-emphasis can overdrive short channels. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
DS15BR400TVSX/NOPB - 4-Ch LVDS Buffer 2Gbps | TI
The Texas Instruments DS15BR400TVSX/NOPB is a 4-channel LVDS buffer/repeater with pre-emphasis supporting data rates up to 2 Gbps, powered from a single 3.0V to 3.6V supply in a 48-pin TQFP (PFB, 7x7 mm) package. Each channel delivers a typical propagation delay of 1.0 ns with 3 pF input capacitance, and the device consumes a typical 215 mA supply current (approximately 578 mW) across the full -40C to +85C industrial temperature range. An LVDS (Low-Voltage Differential Signaling) buffer/repeater belongs to the broader family of high-speed interface ICs, sitting within the signal-conditioning hierarchy between a differential line driver and the receiving ASIC or serializer. Its role is to regenerate degraded differential signals, restoring amplitude and sharpness so that data can traverse lossy media such as backplanes and cables without violating eye-mask requirements at the receiver. Key differentiating features include the 2 Gbps per-channel data rate, pre-emphasis that overcomes ISI (inter-symbol interference) jitter introduced by lossy transmission media, and a flow-through pinout that minimizes internal device jitter while dramatically simplifying PCB routing. The differential inputs interface directly to standard LVDS and Bus LVDS signal levels, such as those generated by TI 10-, 16-, and 18-bit serializers, making the device a natural companion in SerDes-based video and data-conversion links. Architecturally, the DS15BR400 uses high-speed differential input buffers followed by output drivers with programmable-style pre-emphasis compensation. Because the signal path is analog buffer-based rather than clock-and-data-recovery based, latency is deterministic and low (1.0 ns typical), which matters in phase-critical pixel-clock and sample-clock distribution. High-speed data paths with flow-through pin ordering keep intra-pair skew tight and reduce via stubs. Typical applications include flat-panel display and medical-imaging backplanes carrying FPD-Link or OpenLDI-style LVDS streams, high-speed data acquisition and ADC-to-processor links, and industrial camera or video router systems where 2 Gbps serial streams cross connectors and cable assemblies. When designing with this part, control the inter-pair skew budget and use controlled-impedance 100-ohm differential routing; pre-emphasis settings should be validated on your specific backplane attenuation, since over-emphasis can increase crosstalk at the far end. This page synthesizes distributor pricing context, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
DS90C031TM - 155.5 Mbps Quad LVDS Driver | Texas Instruments
The Texas Instruments DS90C031TM is a quad CMOS differential line driver supporting data rates above 155.5 Mbps and 77.7 MHz using Low Voltage Differential Signaling. It accepts TTL/CMOS inputs and translates them into low-voltage differential outputs in a 16-pin SOIC package. Each channel provides a differential driver, enabling four independent point-to-point links from one interface IC. The device is positioned for high-speed point-to-point systems requiring low power dissipation and reduced-noise signaling. An LVDS line driver is a differential interface circuit that launches two complementary, low-voltage signals through a balanced conductor pair. The receiving endpoint detects the voltage difference while rejecting common-mode noise. Within the broader hierarchy, LVDS signaling belongs to differential digital interfaces and interface ICs; a line driver converts a logic-level source into a physically suitable low-voltage differential signal for balanced cable or PCB links. The DS90C031 supports more than 155.5 Mbps data rates and uses a 5 V supply according to the supplied distributor specifications. Its four outputs are designed around approximately 350 mV differential signaling. Compared with conventional single-ended CMOS links, the differential architecture can improve noise immunity and permit useful transmission distance when implemented with controlled-impedance interconnects, proper terminations, and compatible receivers. The CMOS input stage accepts TTL/CMOS logic levels, allowing the driver to sit directly between a digital controller or serializer and a balanced cable connection. Four channels provide useful density where several independent links are required, such as instrumentation, industrial data acquisition, telecommunications equipment, and test systems. The companion line receiver identified on TI's product page is the DS90C032. For point-to-point LVDS links, route each differential pair on a controlled-impedance PCB trace or use a cable with the required impedance. Provide the receiver-side termination specified by the system design, keep differential traces close together, and minimize stubs and layer transitions. The TTL/CMOS interface and four-channel organization make the part convenient, but signal-integrity layout and an appropriate receiver remain central to reliable operation. This page combines the verified 155.5 Mbps, four-driver, 5 V, 16-SOIC, and 350 mV characteristics with sourcing guidance and implementation considerations that go beyond a basic distributor listing.

DS90CR211MTDX - 21-Bit LVDS Channel Link Transmitter | TI
The DS90CR211MTDX is a 21-bit Channel Link transmitter from Texas Instruments that converts 21 bits of CMOS/TTL data into three LVDS (Low Voltage Differential Signaling) data streams. A phase-locked transmit clock is transmitted in parallel with the data streams, allowing the receiver to recover the clock and data with minimal skew. The device operates from a 4.5V to 5.5V supply and is available in a 48-pin TSSOP package (48-TFSOP, 0.240", 6.10mm width). It supports data rates up to 840 Mbps, making it suitable for high-speed point-to-point data transmission in display interfaces, industrial cameras, and medical imaging systems. Channel Link is a proprietary high-speed digital interface technology developed by National Semiconductor (now part of Texas Instruments) that reduces the number of parallel data lines by serializing them into LVDS pairs. This technology is widely used in flat panel displays, digital video interfaces, and other applications requiring high bandwidth over a limited number of wires. The DS90CR211MTDX is part of the Channel Link family, which includes transmitters and receivers that work together to provide a complete serialization/deserialization solution. Key features of the DS90CR211MTDX include a 21-bit parallel input, three LVDS data outputs plus one clock output, and a maximum data rate of 840 Mbps. The device has a typical power consumption of [DATA_NEEDED: power consumption] and supports a wide operating temperature range of -40°C to +85°C. The LVDS outputs feature low voltage swing (typically 350 mV) and high noise immunity, making the device ideal for noisy industrial environments. The transmitter also includes a power-down mode to reduce power consumption when not in use. The DS90CR211MTDX uses a phase-locked loop (PLL) to generate the high-speed serial clock from the parallel input clock. The PLL ensures low jitter and accurate data alignment, which is critical for reliable data transmission at high speeds. The device also features built-in termination resistors on the LVDS outputs, simplifying PCB layout and reducing external component count. The TSSOP package offers a compact footprint with a 0.65mm lead pitch, suitable for space-constrained designs. Typical applications include flat panel displays, digital video interfaces, industrial cameras, medical imaging, and automotive infotainment systems. The device is particularly well-suited for applications requiring high-speed data transfer over long distances with minimal EMI, as LVDS signaling inherently provides low electromagnetic interference. The DS90CR211MTDX is also used in test and measurement equipment where high-speed data acquisition is required. When designing with the DS90CR211MTDX, ensure that the LVDS output traces are impedance-matched (typically 100Ω differential) and kept as short as possible to minimize signal integrity issues. The power supply should be well-decoupled with 0.1µF and 10µF capacitors placed close to the VCC pins. The PLL requires a clean power supply to achieve optimal jitter performance, so avoid routing the power traces near high-speed switching signals.
DS90CR282MTDX - 28-Bit LVDS Channel Link Receiver | Texas Instruments
The Texas Instruments DS90CR282MTDX is a 28-bit Channel Link receiver that converts four LVDS (Low Voltage Differential Signaling) data streams back into 28 bits of CMOS/TTL parallel data. It is designed to pair with the DS90CR281 transmitter, which serializes 28 bits of CMOS/TTL data into four LVDS data streams along with a phase-locked transmit clock. The receiver operates from a 4.5V to 5.5V supply and is housed in a 56-pin TSSOP (TFSOP) package, making it suitable for high-speed point-to-point data transmission over twisted-pair or PCB traces. Channel Link is a proprietary high-speed digital interface technology developed by National Semiconductor (now part of Texas Instruments) that reduces the number of parallel data lines by serializing them into differential pairs. This technology is widely used in flat panel displays, digital video interfaces, and other high-bandwidth applications where reducing cable count and EMI is critical. The DS90CR282MTDX is a receiver in this family, providing the deserialization function that reconstructs the original parallel data bus. Key features of the DS90CR282MTDX include support for data rates up to 66 MHz (as per the DS90CR285 transmitter), a 28-bit parallel interface, and LVDS signaling that provides low EMI and high noise immunity. The device includes an internal PLL for clock recovery and supports a power-down mode to reduce quiescent current. The 56-pin TSSOP package offers a compact footprint for space-constrained designs. Technically, the DS90CR282MTDX uses a differential signaling scheme with a nominal 3.5mA output current and a typical 100-ohm termination resistor at the receiver input. The receiver's input common-mode voltage range is designed to accommodate ground potential differences between transmitter and receiver. The device is specified for the commercial temperature range (0°C to 70°C) and is available in tape and reel packaging. Typical applications include flat panel display interfaces, digital video links, and industrial imaging systems where high-speed serial data transmission over short distances is required. The DS90CR282MTDX is often used in conjunction with the DS90CR281 transmitter to form a complete Channel Link solution. When designing with this device, ensure proper termination of the LVDS lines with 100-ohm resistors close to the receiver inputs, and maintain controlled impedance on the PCB traces to minimize signal reflections. The power-down pin can be used to reduce power consumption when the link is idle.
DS90LV017M - 600Mbps Single LVDS Driver | Texas Instruments
The Texas Instruments DS90LV017M is a single high-speed differential driver optimized for low-power LVDS links, with a 3.3 V supply, support for data rates in excess of 600 Mbps (300 MHz), and an 8-lead narrow SOIC package. It is designed for point-to-point differential signaling in EIA-644-A and TIA-644-A systems. An LVDS driver is a line and bus driver that converts a low-voltage logic input into a balanced differential output. LVDS belongs to the interface IC hierarchy and uses small signal swings, common-mode biasing, and differential transmission to support high data rates while limiting electromagnetic interference. The DS90LV017M is specifically optimized for a single differential output rather than a multi-channel transceiver. Key features include a 3.3 V supply voltage, a typical LVDS output swing of 355 mV, and a current-mode output architecture. The current-mode design helps maintain low power dissipation at high frequencies, while short-circuit fault-current limiting reduces stress during output faults. The device also supports data rates above 600 Mbps and is available in the narrow 8-pin SOIC package. The DS90LV017M operates across the -40°C to +85°C commercial temperature range. Its 8-lead SOIC construction supports conventional surface-mount assembly and provides a practical option for interfaces requiring one LVDS transmit channel. The verified package references identify a 0.45 V-related LVDS driver specification and an 8-pin SOIC format, while several search results also associate the family with SOT-23 variants; the M suffix and supplied comparison data specifically identify DS90LV017M as the SOIC version. Typical applications include high-speed point-to-point data links, industrial control interfaces, test equipment, instrumentation, and embedded systems that transmit clock or data signals over a short differential channel. In these systems, the driver is used with a matched LVDS receiver and controlled-impedance PCB traces. The principal design consideration is transmission-line matching. Terminate the differential pair correctly, provide a suitable reference-plane return path, minimize stub lengths, and observe the receiver's input and termination requirements. Because the device is a single-ended-to-differential driver, system-level skew and common-mode behavior must also be checked against the receiving circuit. This page combines the verified manufacturer and distributor specifications with package-level selection guidance, application examples, and an explicit comparison against same-family alternatives. It also distinguishes verified drop-in candidates from parts that may be electrically similar but cannot be assumed to share the DS90LV017M pinout.
DS90LV031TM - Quad 400 Mbps LVDS Driver | Texas Instruments
The Texas Instruments DS90LV031TM is a quad CMOS differential line driver supporting data rates in excess of 400 Mbps (200 MHz) in a 16-pin SOIC package. It accepts low-voltage LVTTL or LVCMOS inputs and translates each digital input into a low-voltage differential LVDS output of approximately 350 mV. The device provides four independent driver channels for high-speed point-to-point interfaces. An LVDS differential line driver is an interface IC that converts single-ended CMOS logic into a pair of complementary low-voltage signals. The receiver detects the voltage difference between those signals, allowing simultaneous noise rejection, low EMI, and reliable data transfer over balanced interconnects. Within the broader hierarchy, DS90LV031TM is a line driver within interface ICs, implemented as a low-power CMOS differential signaling device. Key features include four CMOS-to-LVDS driver channels, operation above 400 Mbps, LVTTL or LVCMOS input compatibility, and differential output voltage of approximately 350 mV. Common enables allow the outputs to be controlled together, which supports system-level power management and controlled output states. The low-power architecture is intended for high-speed point-to-point communication systems requiring more efficient alternatives to older high-power pseudo-ECL interface devices. The DS90LV031TM translates four LVCMOS or LVTTL data streams into four balanced LVDS pairs. Differential signaling reduces sensitivity to common-mode noise compared with single-ended transmission, while the approximately 350 mV output amplitude helps control EMI and allows reliable communication over suitable cables or controlled-impedance PCB traces. Its high data-rate capability makes it relevant to clock distribution, parallel data transfer, industrial links, and test equipment. Typical applications include high-speed backplane links, point-to-point industrial data transfer, parallel-to-serial interface bridges, video or control-data transport, and clock distribution. When used with the companion DS90LV032A receiver, the device provides a complete LVDS transmit and receive path over balanced interconnects. PCB implementation should preserve differential pair symmetry, provide a continuous return path, and place decoupling close to the supply pins. The 16-pin SOIC package should be oriented according to the manufacturer pinout, with enable and ground connections handled before high-speed signal routing. Exact pin names, supply limits, output timing limits, and termination guidance must be confirmed in the manufacturer datasheet before release to production. This product page combines verified distributor availability and pricing with manufacturer-family information, cross-reference results, package details, and practical guidance for evaluating the DS90LV031TM as a drop-in LVDS line-driver choice.
FMS6502 - 8x6 Video Switch Matrix TSSOP-24 | onsemi
The onsemi FMS6502 is an 8-input, 6-output video switch matrix with integrated output drivers, input clamp, and bias circuitry, housed in a 24-pin TSSOP (MTC) package. It routes any of eight video inputs to any of six outputs under I2C control, with one output driver per output channel. A video switch matrix (also called a crosspoint switch) is an analog routing IC that belongs to the video conditioning and audio/video ASSP family within the broader interface IC category. Its role in the system hierarchy is to sit between multiple video sources (such as decoders, tuners, or SoC outputs) and multiple video sinks (encoders, displays, or recorders), replacing banks of discrete analog multiplexers and buffer amplifiers. Key features include an 8x6 crosspoint architecture in which each input can be routed to one or more outputs, while only one input may drive any given output at a time, preventing bus contention. Each input supports an integrated clamp option that sets the output sync tip level of video with sync to approximately 300 mV, which is essential for maintaining correct black-level reference in composite and S-Video signals. Alternatively, the input may be internally biased to center outputs without sync (Chroma, Pb, Pr) at a defined mid-level, supporting component video formats. Architecturally, the device integrates output drivers on every output, eliminating the external buffer stages that discrete crosspoint solutions require. The I2C serial interface allows full matrix reconfiguration, and the onsemi VIPDEMO evaluation platform supports single-register read and write operations for I2C bring-up and debugging. Typical applications include set-top boxes, DVD recorders and players, video servers, CCTV/security video routing, automotive rear-seat entertainment, and any multi-source/multi-display video system requiring glitch-free source selection. Design consideration: choose clamp mode for signals containing sync and bias mode for sync-less component signals; incorrect mode selection shifts the DC operating point of the downstream video path. Verify I2C register maps against the onsemi datasheet before board bring-up.

FSA4480UCX - USB Type-C Audio Switch 25-WLCSP | onsemi
The onsemi FSA4480UCX is a high-performance USB Type-C port multimedia analog audio switch that supports analog audio headsets, housed in a 25-ball WLCSP package (2.24 x 2.28 mm) with a 6-channel switch configuration and integrated protection function. A USB Type-C analog audio switch is a special-purpose analog multiplexer that lets a single reversible USB Type-C connector carry multiple signal types simultaneously. In the port-sharing hierarchy, it sits between the USB Type-C receptacle and the application processor's USB PHY and audio codec, routing USB 2.0 data, analog left/right audio, sideband-use (SBU) lines, and analog microphone signals onto the shared pins. This eliminates dedicated 3.5 mm jacks and enables slimmer smartphone and tablet designs. Key features of the FSA4480 include sharing of a common USB Type-C port to pass USB 2.0 signal, analog audio, sideband use wires, and analog microphone signal, plus support for high voltage on the SBU port and USB port on the receptacle side - critical because SBU pins can be exposed to fault voltages during accessory attach and cable orientation changes. Technically, the device is fabricated as an integrated CMOS analog switch array with low on-state characteristics suited to audio-band signal integrity. The WLCSP (wafer-level chip-scale package) die size of 2.24 x 2.28 mm minimizes board area and shortens analog signal traces, which reduces insertion loss and crosstalk for audio and high-speed USB routing. The FSA4480 is documented in the onsemi datasheet 'USB Type-C Analog Audio Switch with Protection Function' (published 2019-11-22, 29 pages). Typical applications include smartphones and tablets using a single Type-C connector for audio accessories, laptop and notebook audio-headset sharing, docking stations, and true-wireless charging cases requiring port consolidation. The protection function makes it especially suitable for consumer ports exposed to harsh accessory environments. Design consideration: verify SBU high-voltage tolerance against your application's worst-case fault scenario, and keep WLCSP routing impedance-controlled; WLCSP packages require careful PCB fanout and do not support rework as easily as QFN alternatives. This page synthesizes distributor pricing, cross-reference guidance, and practical design notes not found in the manufacturer datasheet alone.
FUSB302BMPX - USB Type-C Controller with PD | onsemi
The onsemi FUSB302BMPX is a programmable USB Type-C controller with USB Power Delivery (PD) support, delivered in a 14-pin MLP (2.5 x 2.5 mm) package. It handles Type-C attach detection, cable orientation detection, and integrates the physical layer of the USB BMC (Biphase Mark Coding) power delivery protocol, supporting power roles of DRP (Dual Role Port), SRC (Source), and SNK (Sink, its default configuration). A USB Type-C controller is a bridge IC between a system embedded controller and the USB Type-C connector. It sits in the product hierarchy of interface ICs -> USB controllers -> USB Type-C/PD controllers, and is responsible for CC-line communication, role swap, and PD message exchange, enabling up to 100 W of power delivery over the USB-C cable without dedicated high-speed analog circuitry in the main SoC. Key features of the FUSB302BMPX include full USB Type-C attach and orientation detection, an integrated BMC PD PHY enabling up to 100 W power and role swap, and support for the alternative interfaces of the Type-C specification. The device communicates with the host over an I2C interface and provides an interrupt output for event-driven operation, keeping host firmware overhead low. Technically, the FUSB302B integrates the CC-line comparators, BMC transmit/receive physical layer, and digital protocol engine in a compact 2.5 x 2.5 mm MLP-14 footprint. Because the PD PHY is on-chip, designers avoid implementing time-critical BMC encoding in software, improving USB-IF compliance robustness. onsemi provides reference code for the FUSB302B for easy implementation across several embedded controller platforms. Typical applications include USB-C power adapters and chargers, smartphones and tablets, notebooks and docking stations, power banks, and monitor/TV USB-C ports. Its small 2.5 x 2.5 mm MLP package suits space-constrained portable designs, while 100 W PD support covers laptop charging scenarios. A key design consideration: the FUSB302BMPX defaults to SNK (sink) role, so source or DRP behavior must be programmed via the I2C register interface. CC-line ESD protection and correct Rp/Rd termination selection are also critical for reliable attach detection. This page synthesizes distributor pricing, the verified onsemi drop-in replacement guidance for FUSB302MPX, and practical design notes not found in the manufacturer datasheet alone.
