7.1 Overview

The TMUXHS221 is an analog passive mux with 2:1/1:2 multiplexer/demultiplexer that can work for any low-speed, high-speed, differential or single ended signals. The signals must be within the allowable voltage range of −0.3 to 3.6 V. The device is optimized for eUSB2 and USB 2.0 LS, FS, and HS signaling.

Excellent dynamic characteristics of the device allow high speed switching with minimal attenuation to the signal eye diagram with very little added jitter. While the device is recommended for the interfaces up to 3 Gbps, actual data rate where the device can be used highly depends on the electrical channels. For low loss channels where adequate margin is maintained, the device can potentially be used for higher data rates.
