3 Description

The TMUXHS4212 is a high-speed bidirectional

passive switch in mux or demux configurations. It is

suited for many applications including USB Type-C™

and PCI Express. The TMUXHS4212 is a generic

analog differential passive mux or demux that works

for many high-speed differential interfaces with data

rates up to 16 Gbps. The device can be used for

higher data rates where the electrical channel has

signal integrity margins. The TMUXHS4212 supports

differential signaling with common mode voltage

range (CMV) of up to 0 to 1.8 V and with differential

amplitude up to 1800 mVpp. Adaptive CMV tracking

ensures the channel through the device remains

unchanged for the entire common mode voltage

range.

The dynamic characteristics of the TMUXHS4212

allows high-speed switching, minimum attenuation to

the signal eye diagram, and with very little added

jitter. The device's silicon design is optimized for

excellent frequency response at higher frequency

spectrum of the signals. Its silicon signal traces and

switch network are matched for best intra-pair skew

performance.

The TMUXHS4212 has an extended industrial

temperature range that suits many rugged

applications including industrial and high reliability use

cases.
