High-Speed Switch and Redriver Guide
Best-in-Class Performance, Reliability and Robustness
Overview
In today’s high performance systems, designers are constantly pushing for faster data throughput and greater
design exibility. This push
often leads to signal integrity issues in transmission. Texas Instruments’ broad
portfolio of switches and redrivers
for high-speed signaling help solve these issues by delivering high signal
integrity, low output jitter, and the lowest power consumption. These products support many standards.
This guide helps navigate through the extensive TI portfolio to nd the best product for your designs.
Key Applications
