Product details
Overview
DS92LX1622SQX/NOPB from Texas Instruments is a Channel Link III deserializer IC for high-speed image data transport over single differential pair, supporting 16-bit payload at up to 800 Mbits/sec with embedded clock, bi-directional I²C control channel, CRC error detection, and programmable receive equalization. It operates from 10–50 MHz input clock, drives up to 10 m shielded twisted-pair, and targets automotive camera-to-ECU links.
For engineers reviewing the DS92LX1622SQX/NOPB datasheet, DS92LX1622SQX/NOPB pinout, DS92LX1622SQX/NOPB application, or DS92LX1622SQX/NOPB equivalent, key selection criteria include its 40-pin WQFN package, 1.8V core supply, LOCK status reporting, PASS output for CRC error indication, and support for AT-speed BIST diagnostics on the serial link.
Technical Context
The DS92LX1622SQX/NOPB implements a CDR-based deserialization architecture with integrated PLL, supporting DC-balanced 8b10b-like encoding to enable AC-coupled interconnects. Its receiver includes programmable equalization to compensate for channel loss over distances up to 10 meters.
It provides a full-duplex bi-directional control channel compliant with I²C protocol (100 kHz), with master/slave mode selection via M/S pin and continuous address decoding via CAD pin. The deserializer outputs parallel LVCMOS data (ROUT[13:0], HSYNC, VSYNC, PCLK) and supports 1.8V or 3.3V I/O voltage levels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar deserializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS90UB954TRGCRQ1 | FPD-Link III deserializer; supports 10-bit 4-lane input, higher max throughput (3.12 Gbps), integrated HDCP, but requires external reference clock | Targeted at infotainment displays with HDMI/MIPI conversion; lacks native I²C back-channel | Choose for higher bandwidth or security-critical automotive displays; avoid if legacy Channel Link III compatibility is required |
| MAX9271GTJ+ | GMSL deserializer; supports longer reach (15 m), daisy-chain capability, and lower power (IDDR ≈ 45 mA), but uses proprietary protocol | Used in ADAS domain controllers with multi-camera fusion; no direct I²C control channel | Prefer for GMSL ecosystem integration or extended cable length; DS92LX1622SQX/NOPB offers simpler I²C-based configuration |
Compared with DS90UB954TRGCRQ1 and MAX9271GTJ+, DS92LX1622SQX/NOPB delivers native Channel Link III interoperability with minimal external components, deterministic latency, and dual-voltage I/O-making it optimal for cost-sensitive, non-HDCP automotive camera links where protocol compatibility and ease of validation are critical.

FAQ
What is the primary function of DS92LX1622SQX/NOPB in a vision system?
The DS92LX1622SQX/NOPB functions as a Channel Link III deserializer that converts high-speed serialized image data (received over a single differential pair) into a parallel 16-bit LVCMOS interface-including ROUT[13:0], HSYNC, VSYNC, and PCLK-for direct connection to processors or display controllers. It also recovers and reports link status via LOCK and PASS pins, enabling real-time system-level fault detection in DS92LX1622SQX/NOPB-based designs.
Does DS92LX1622SQX/NOPB require an external reference clock?
No, DS92LX1622SQX/NOPB does not require an external reference clock. It uses embedded clock technology to recover timing directly from the incoming serialized data stream on RIN+/RIN−. This eliminates clock skew concerns and simplifies PCB layout-unlike alternatives such as DS90UB954TRGCRQ1, which mandates an external reference. The DS92LX1622SQX/NOPB only needs the serialized data input and power supplies to operate.
How does DS92LX1622SQX/NOPB handle data integrity verification?
DS92LX1622SQX/NOPB supports cyclic redundancy check (CRC) on the 16-bit payload, with error detection reported via the dedicated PASS output pin (low = CRC error). This feature is programmable and works in conjunction with the serializer's CRC generation. Unlike parity-only schemes, CRC provides stronger protection against burst errors in DS92LX1622SQX/NOPB links, making it suitable for functional safety applications where data corruption must be flagged immediately.
Can DS92LX1622SQX/NOPB interface with both 1.8V and 3.3V logic systems?
Yes, DS92LX1622SQX/NOPB supports dual I/O voltage operation: its parallel outputs (ROUT[13:0], HSYNC, VSYNC, PCLK) and control pins (SCL, SDA, GPIOs) are compatible with either 1.8V or 3.3V LVCMOS logic levels. VDDIO must be set accordingly, and the device automatically adapts drive strength and thresholds-enabling seamless integration with mixed-voltage host processors or FPGAs without external level shifters in DS92LX1622SQX/NOPB implementations.
What diagnostic capabilities does DS92LX1622SQX/NOPB provide?
DS92LX1622SQX/NOPB includes AT-speed Built-In Self-Test (BIST) activated via the BISTEN pin, allowing real-time validation of the serial link without external pattern generators. It also provides LOCK (PLL lock status) and PASS (CRC pass/fail) outputs for hardware-monitored link health. These features enable automated startup verification and runtime fault detection-critical for DS92LX1622SQX/NOPB deployments in automotive and medical systems requiring high reliability.
