DS92LX1621SQ/NOPB

Overview

The DS92LX1621SQ/NOPB is a serializer from the Texas Instruments Channel Link LX family, designed for high-speed data transmission. It converts sixteen parallel LVCMOS inputs into a single differential CML output. The device supports data rates up to 900 Mb/s and operates within a frequency range of 10 MHz to 50 MHz. It requires dual power supplies: 1.71 V to 1.89 V for I/O and 3 V to 3.6 V for the core. Operating temperatures span from -40°C to +85°C. The component is housed in a 32-pin WQFN package measuring 5 mm by 5 mm with a height of 0.8 mm.

Feature Summary

• Integrates sixteen parallel-to-serial conversion channels for compact interface solutions
• Supports bidirectional communication through a dedicated reverse channel
• Features integrated GPIO capabilities for auxiliary signal control

Applications

• Camera interface modules requiring high-bandwidth video transmission
• FPGA-based systems needing parallel-to-differential serial conversion
• Industrial imaging equipment utilizing frame trigger signals

Procurement Notes

Verify the specific suffix code (SQ, SQE, or SQX) against the required moisture sensitivity level and reel packaging configuration. Confirm that the voltage supply requirements align with the target system design before ordering. Ensure ESD protection protocols are followed during handling due to the small form factor.

Selection Notes

Select this component when sixteen parallel digital inputs must be serialized into a single differential pair. Verify compatibility with the downstream deserializer's clock recovery mechanism. Ensure the PCB layout accommodates the 32-WQFN footprint and provides adequate thermal dissipation for continuous operation at maximum data rates.

Part Context

This part belongs to the DS92LX1621 series, which includes variants like the DS92LX1622. These devices are engineered for low-power, high-performance serializing applications. The series utilizes Channel Link technology to ensure reliable data integrity over long cable runs in noisy environments.

Replacement Considerations

Direct substitutes include DS92LX1621SQE/NOPB and DS92LX1621SQX/NOPB. These variants share identical electrical specifications but differ in packaging format and moisture sensitivity classification. Verify pinout compatibility before substitution.
