What are the key features of DS92LX1621SQX/NOPB?
- 900 Mbps per lane LVDS serialization converts 16 parallel LVDS inputs to 2 high-speed serial LVDS pairs, reducing cable count by 8× in camera and sensor link designs
- Differential Schmitt-trigger LVDS inputs reject common-mode noise up to 400 mVpp, enabling robust operation in EMI-heavy automotive and industrial environments
- I2C interface for configuration and status monitoring allows real-time link management without dedicated control hardware
- 32-pin WQFN-EP package with exposed thermal pad minimizes PCB footprint while providing efficient heat dissipation for continuous 900 Mbps operation
What is DS92LX1621SQX/NOPB used for?
The DS92LX1621SQX/NOPB is designed for camera link aggregation, machine vision backplanes, and automotive surround-view systems where multiple parallel LVDS sensor outputs must be multiplexed onto fewer high-speed serial links over cable or PCB. By serializing 16 LVDS data lanes into just 2 serial pairs at 900 Mbps each, it drastically reduces connector pin count and cable harness complexity in multi-camera driver assistance systems. Industrial test equipment and video capture cards also use the DS92LX1621 to collect parallel LVDS outputs from image sensors and transport them to FPGAs or processors over a minimal high-speed differential link.

Frequently Asked Questions
What is the maximum per-lane data rate of DS92LX1621SQX/NOPB, and how many parallel inputs does it serialize?
The DS92LX1621SQX/NOPB serializes 16 LVDS parallel input lanes into 2 LVDS serial output pairs, each operating at up to 900 Mbps. The total aggregate throughput reaches 1.8 Gbps across both output links, making it suitable for transporting pixel data from 10-bit image sensors at 90 MSPS frame rates over a compact 2-pair serial interface.
How does the differential Schmitt-trigger input architecture benefit automotive camera link designs?
The differential Schmitt-trigger LVDS inputs provide approximately 100 mV hysteresis on top of the standard LVDS 100 mV differential swing threshold, so the device tolerates up to 400 mVpp common-mode noise superimposed on the input signals. In automotive environments where switching regulators, ignition transients, and motor drives inject noise onto camera cable shields, this input architecture prevents spurious bit errors without requiring additional common-mode choke components.
How does I2C configuration work on DS92LX1621SQX/NOPB, and what parameters can be controlled?
The DS92LX1621SQX/NOPB exposes an I2C slave interface operating at 400 kHz Fast-mode, accessible from a host microcontroller or FPGA. Via I2C register writes, the user can configure output pre-emphasis strength, enable or disable individual input channels, read back link lock status, and program the device I2C address to resolve bus conflicts when multiple serializers share one I2C bus.
What PCB trace impedance and termination are required for the 900 Mbps LVDS serial outputs?
The serial LVDS output pairs must be routed as 100 Ω differential controlled-impedance traces with a matched termination resistor of 100 Ω placed within 5 mm of the receiving end. At 900 Mbps, unterminated stubs longer than 5 mm introduce reflections that degrade eye opening below the 150 mV minimum differential threshold, so receiver termination and trace length matching to within 5 mil are essential for reliable operation.
When should a designer choose DS92LX1621SQX/NOPB over DS92LX1222 for a 16-channel camera aggregation link?
DS92LX1621SQX/NOPB serializes 16 LVDS inputs to 2 serial output pairs at 900 Mbps each (1.8 Gbps aggregate), whereas DS92LX1222 handles 12 inputs to 2 outputs at a lower throughput. The 16-input variant is preferred when connecting to image sensors with 14-bit or 16-bit parallel LVDS pixel buses that exceed the 12-channel capacity, avoiding the need for a second serializer IC and the additional PCB area and power that would entail.
