Overview
The DS92LX1621SQE/NOPB is a serializer manufactured by Texas Instruments, designed for high-speed data transmission. It accepts LVCMOS inputs and generates CML outputs. The device supports a maximum data rate of 900 Mbps. It operates within a power supply range of 3 V to 3.6 V for the main logic and 1.71 V to 1.89 V for I/O or auxiliary circuits. The component is housed in a 32-pin WQFN package with dimensions of 5 mm x 5 mm and a height of 0.8 mm. It functions as a single-channel serializer with one output. The operational temperature range spans from -40 °C to +85 °C.
Feature Summary
- Converts parallel LVCMOS data into a serial CML stream for long-distance transmission.
- Supports DC-balanced channel encoding for reliable signal integrity.
- Includes GPIO capabilities for bidirectional control and status monitoring.
Applications
- Camera-to-FPGA data links in imaging systems.
- Industrial machine vision interfaces.
- Medical imaging equipment signal transmission.
Procurement Notes
Verify the specific suffix 'SQE' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the ordering information aligns with the latest revision history to avoid discrepancies in package dimensions or thermal performance specifications during procurement.
Selection Notes
Select this component when a serializer is required to interface LVCMOS sources with CML receivers at speeds up to 900 Mbps. Consider the 32-pin WQFN package constraints for PCB layout. Verify that the system clock frequencies fall within the supported 10 MHz to 50 MHz input range for proper channel locking and data recovery.
Part Context
This part belongs to the Texas Instruments Channel Link LX series, which focuses on low-power, high-speed serialization solutions. The DS92LX1621 is specifically engineered for applications requiring robust data transmission over twisted pair or coaxial cables, often paired with compatible deserializers like the DS92LX1622.
Replacement Considerations
The DS92LX1621SQ/NOPB is a direct substitute with identical functionality but potentially different packaging or reel specifications. Verify pin compatibility and electrical parameters before swapping.
