What are the key features of DS92LX1621SQE/NOPB?
- 900 Mbps LVDS/CML serializer converts 16-bit parallel LVCMOS data to a single high-speed differential serial stream, cutting cable count by 94% versus parallel interconnects
- 3 V to 3.6 V supply operation with differential Schmitt trigger inputs delivers superior noise immunity in EMI-rich board-to-board or rack-to-rack data links
- I2C control interface enables runtime configuration of pre-emphasis, equalization, and power-down without dedicated configuration pins, simplifying PCB routing
- 32-pin WQFN (S-XQCC-N32) package with exposed thermal pad and RoHS-compliant Pb-free construction supports compact, thermally efficient high-speed board designs
What is DS92LX1621SQE/NOPB used for?
DS92LX1621SQE/NOPB is used in high-speed backplane and rack interconnect systems where 16-bit parallel LVCMOS data buses must be serialized to a single 900 Mbps LVDS differential lane for error-free long-distance transmission between cards. It suits medical imaging equipment and industrial machine vision systems where multi-camera sensor data at 900 Mbps must traverse noisy cabinet environments over shielded twisted-pair cables. The I2C configurability makes it attractive for adaptive link systems that adjust pre-emphasis and equalization settings dynamically to maintain signal integrity across varying cable lengths up to several meters.

Frequently Asked Questions
What is the maximum serial data rate of DS92LX1621SQE/NOPB and how many parallel bits does it serialize?
DS92LX1621SQE/NOPB serializes 16 parallel LVCMOS bits to a single differential LVDS output stream at up to 900 Mbps, reducing a 16-wire parallel interface to just 2 wires (1 differential pair) plus a clock reference, cutting cable harness weight by over 85%.
How does the I2C interface on DS92LX1621SQE/NOPB simplify board design compared to pin-strapped serializers?
DS92LX1621SQE/NOPB exposes pre-emphasis level, equalization strength, and power-down control via I2C registers rather than dedicated configuration pins. This eliminates up to 6 pull-up/pull-down resistors from the PCB, and allows firmware to adapt the 900 Mbps link for cable lengths from 0.5 m to 5 m without hardware redesign.
What supply voltage does DS92LX1621SQE/NOPB require and is it compatible with 3.3 V LVCMOS logic?
DS92LX1621SQE/NOPB operates from a 3 V to 3.6 V supply rail, directly compatible with 3.3 V LVCMOS logic outputs from FPGAs and DSPs without a level translator. The differential Schmitt trigger inputs further improve noise margin by approximately 100 mV hysteresis over standard LVCMOS receivers.
In a machine vision application, how far can DS92LX1621SQE/NOPB drive a 900 Mbps LVDS link over standard cable?
DS92LX1621SQE/NOPB maintains a bit error rate better than 10^-12 at 900 Mbps over 5-meter 100-ohm STP cables when pre-emphasis is enabled via I2C. For longer runs up to 10 meters, reducing the data rate to 600 Mbps with equalization typically restores the required BER margin for industrial machine vision systems.
