DS92LV0421SQX/NOPB

Overview

The DS92LV0421SQX/NOPB is a serializer from the Texas Instruments DS92LV0421 series, designed for high-speed data transmission. It converts four parallel LVDS inputs into a single serial CML output stream with a maximum data rate of 2.1 Gb/s. The device operates within a supply voltage range of 1.7 V to 3.6 V and supports an operating temperature range from -40°C to +85°C. It is housed in a 36-pin WQFN package (6x6 mm) with a bottom exposed pad for thermal management. This component complies with RoHS standards and has a Moisture Sensitivity Level (MSL) of 3.

Feature Summary

• Supports Channel Link II interface protocol for reliable high-speed serialization
• Converts low-voltage differential signaling (LVDS) parallel data to current-mode logic (CML) serial output
• Integrated clock recovery circuitry for synchronization without external clock distribution

Applications

• High-definition video signal transmission systems
• Industrial automation control interfaces
• Medical imaging equipment data links

Procurement Notes

Verify the specific suffix code against the manufacturer's latest datasheet to confirm package type and material composition. Ensure that the ordering information matches the required moisture sensitivity level and lead-free status. Confirm compatibility with existing board layouts regarding the WQFN-36 footprint and thermal pad requirements before finalizing procurement orders.

Selection Notes

Select this component when a 4-to-1 LVDS to CML serialization ratio is required at speeds up to 2.1 Gb/s. Consider the 36-pin WQFN package constraints for PCB space and thermal dissipation needs. Evaluate the 1.7 V to 3.6 V supply voltage flexibility against system power rails. Verify that the Channel Link II protocol aligns with the receiving deserializer specifications in the target application design.

Part Context

This part belongs to the DS92LV0421 family of serializers manufactured by Texas Instruments. It is specifically engineered for applications requiring high-bandwidth data conversion from parallel LVDS sources to serial CML outputs. The SQX suffix indicates a specific tape-and-reel packaging configuration suitable for automated surface-mount assembly processes.

Replacement Considerations

The DS92LV0421SQE/NOPB is documented as a parameter-equivalent alternative. Verify pinout compatibility and package dimensions before substitution. Ensure that any replacement maintains the same data rate capabilities and electrical characteristics defined in the official datasheet.
