DS92LX2121SQ/NOPB

Overview

The DS92LX2121SQ/NOPB is a serializer manufactured by Texas Instruments, designed for high-speed data transmission applications. It accepts 21 parallel LVCMOS inputs and serializes them into a single CML output stream. The device supports a maximum data rate of 1.05 Gbps per channel. It operates within a supply voltage range of 1.71 V to 1.89 V for the core and 3 V to 3.6 V for I/O. The component is housed in a 40-WQFN package with dimensions of 6x6 mm and is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates 21 differential input channels for high-density signal serialization
• Converts parallel LVCMOS logic levels to low-voltage CML signaling for long-distance transmission
• Supports data rates up to 1.05 Gbps to minimize cable count in complex systems

Applications

• Industrial machine vision systems requiring reduced cabling complexity
• Automotive camera interfaces connecting sensors to processing units
• Medical imaging equipment needing reliable high-bandwidth data links

Procurement Notes

Verify the specific suffix 'SQ' against the manufacturer's official documentation to confirm package variant and tape/reel specifications. Ensure that the ordering part number matches the exact electrical and mechanical requirements of the design. Cross-reference the datasheet revision date to confirm compatibility with current manufacturing standards and RoHS compliance status before finalizing procurement orders.

Selection Notes

Select this component when a system requires serializing a large number of parallel digital signals into a single high-speed lane. It is suitable for designs where reducing the number of cables between sensor arrays and processors is critical for space or weight constraints. Verify that the host processor can handle the corresponding deserialization and that the board layout supports the required CML trace impedance and length matching.

Part Context

This device belongs to the Channel Link III family of serializers, which are distinct from FPD-Link or V3Link products. It is engineered for industrial and automotive environments where robust performance over extended temperature ranges is required. The series provides a solution for replacing bulky multi-cable harnesses with a single high-speed serial link, simplifying assembly and improving reliability in harsh conditions.

Replacement Considerations

The DS92LX2121SQE/NOPB is a parameter-equivalent alternative with a different package suffix. Designers should verify pinout compatibility and thermal characteristics before substitution. Other devices in the DS92LV0421 series offer similar serialization functions but with different input counts and data rates.
