DS92LV0421SQ/NOPB

Overview

The DS92LV0421SQ/NOPB is a serializer manufactured by Texas Instruments, part of the Channel Link II family. It converts four parallel LVDS inputs into a single high-speed CML output stream with a maximum data rate of 2.1 Gb/s. The device operates on a supply voltage ranging from 1.7 V to 3.6 V and supports an industrial temperature range of -40°C to +85°C. It is housed in a 36-pin WQFN package (6x6 mm) suitable for surface-mount applications.

Feature Summary

• Converts four parallel LVDS input channels into a single serialized CML output stream
• Supports high-speed data transmission up to 2.1 Gb/s per channel
• Compatible with standard LVDS signaling interfaces for low-power operation

Applications

• High-definition video signal transmission systems
• Industrial automation control panels requiring long-distance serial communication
• Medical imaging equipment interface modules

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the ordering suffix matches the required package variant and environmental compliance standards. Confirm lead times and moisture sensitivity levels prior to placement, as these factors impact storage and reflow soldering requirements during assembly.

Selection Notes

Select this component when a compact solution is needed to serialize multiple LVDS lines into a single differential pair. Compare pin counts and I/O configurations against alternative serializers in the DS92LV04xx series to ensure compatibility with existing PCB layouts and signal integrity requirements.

Part Context

This device belongs to the DS92LV0421 series, which includes complementary deserializers like the DS92LV0422. These components are designed to work together in point-to-point links, providing a complete serialization/deserialization solution for high-bandwidth digital signals in space-constrained environments.

Replacement Considerations

The DS92LV0421SQE/NOPB is a documented parameter-equivalent substitute. Verify that the specific suffix variations do not alter electrical characteristics or packaging dimensions before implementing any cross-references in production designs.
