Product details
Overview
DS92LX1622SQE/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, CRC error detection, and bi-directional I²C control channel. 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 DS92LX1622SQE/NOPB datasheet, DS92LX1622SQE/NOPB pinout, DS92LX1622SQE/NOPB application, or DS92LX1622SQE/NOPB equivalent, key selection criteria include its 40-pin WQFN (6 mm × 6 mm) package, 1.8 V core supply, programmable receive equalization, LOCK status reporting, and AT-speed BIST diagnostics for link integrity validation.
Technical Context
The DS92LX1622 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), featuring single-pin ID addressing via CAD resistor divider and configurable GPIOs. The deserializer outputs parallel LVCMOS data (16-bit + HSYNC/VSYNC/PCLK) with selectable output edge timing and supports both 1.8 V and 3.3 V I/O interfaces.

FAQ
What is the primary function of DS92LX1622SQE/NOPB in a camera system?
The DS92LX1622SQE/NOPB serves as a deserializer that converts high-speed Channel Link III serial data-received over a single differential pair-into parallel 16-bit image data with synchronized HSYNC, VSYNC, and PCLK signals. In automotive camera systems, DS92LX1622SQE/NOPB enables reliable, low-skew transmission from camera sensor to ECU while supporting diagnostics via LOCK and PASS outputs.
Does DS92LX1622SQE/NOPB require an external reference clock?
No, DS92LX1622SQE/NOPB does not require an external reference clock. It recovers timing from the incoming serialized data stream using its integrated CDR and PLL. The DS92LX1622SQE/NOPB datasheet explicitly states "No Reference Clock Required on Deserializer," enabling simplified system design and reduced component count compared to clock-dependent alternatives.
How does DS92LX1622SQE/NOPB handle data integrity verification?
DS92LX1622SQE/NOPB supports programmable CRC (Cyclic Redundancy Check) on the 16-bit payload, with error detection reported via the dedicated PASS output pin (low = CRC error detected). This real-time link integrity check is complemented by AT-speed BIST and LOCK status reporting, giving DS92LX1622SQE/NOPB comprehensive diagnostic capability for safety-critical imaging links.
What package type and thermal requirements apply to DS92LX1622SQE/NOPB?
DS92LX1622SQE/NOPB uses a 40-pin WQFN package (6 mm × 6 mm, RTA) with an exposed thermal pad (DAP) that must be connected to the PCB ground plane using at least 16 vias. Its thermal resistance is θJA = 28.0 °C/W (with 16 vias), and proper thermal design ensures reliable operation across −40°C to +85°C ambient conditions - a requirement confirmed in the DS92LX1622SQE/NOPB datasheet.
Can DS92LX1622SQE/NOPB operate with both 1.8 V and 3.3 V I/O interfaces?
Yes, DS92LX1622SQE/NOPB supports dual-voltage I/O: its core logic runs at 1.8 V, while the parallel interface (ROUT[13:0], HSYNC, VSYNC, PCLK) and control pins (SCL, SDA, GPIO) are compatible with either 1.8 V or 3.3 V LVCMOS levels. This flexibility allows DS92LX1622SQE/NOPB to interface directly with diverse host processors without level-shifting circuitry.
