DS92LV2421SQ/NOPB

Overview

The DS92LV2421SQ/NOPB is a serializer manufactured by Texas Instruments, designed for high-speed data transmission applications. It converts parallel LVCMOS inputs into a serial CML output stream. The device supports a maximum data rate of 2.1 Gb/s and accommodates 24 input channels with a single output. It operates within a supply voltage range of 1.7 V to 3.6 V and functions reliably across an extended temperature range from -40°C to +85°C. The component is housed in a 48-pin WQFN package suitable for surface-mount technology.

Feature Summary

• Converts 24-bit parallel LVCMOS data into a serial CML output stream
• Supports data rates up to 2.1 Gb/s for high-bandwidth transmission
• Compatible with Channel Link II interface protocols

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents before procurement. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and avoid counterfeit components.

Selection Notes

Select this serializer when interfacing 24-bit parallel sources with serial LVDS/CML receivers requiring up to 2.1 Gb/s throughput. Ensure the system power supply aligns with the 1.7 V to 3.6 V operating range. Verify that the PCB layout supports the 48-pin WQFN footprint and thermal requirements for the intended operating environment.

Part Context

This component belongs to the DS92LV series of serializers from Texas Instruments, which are engineered for robust serializing/deserializing tasks. It pairs typically with compatible deserializers like the DS92LV2422 to form complete point-to-point links. The series is characterized by low jitter performance and compatibility with standard industrial communication protocols.

Replacement Considerations

The DS92LV2421SQE/NOPB is a parameter-equivalent alternative within the same family, offering identical electrical specifications but potentially differing in packaging or reel configuration. Verify pinout compatibility and thermal characteristics before substitution.
