3 Description

The TMUXHS4446 is a high-speed bidirectional

passive crosspoint switch or cossbar (Xbar). This

device is used to switch between USB 3.2 Gen2

SuperSpeed and DisplayPort 1.4/2.1 (up to 10Gbps

UHBR10) signals over a USB Type-C also known as

USB-C interface. The device also provides switching

for the low-speed SBU signals that are used for

DisplayPort auxiliary channels. The TMUXHS4446

supports differential signaling with a common mode

voltage (CMV) range of 0V to 1.8V and a differential

amplitude from 0V to 1800mVpp. Adaptive CMV

tracking enables the channel through the device

to remain unchanged for the entire common-mode

voltage range.

The dynamic characteristics of the TMUXHS4446

allows high-speed switching with minimum attenuation

to the signal eye diagrams, and very little added

jitter. The silicon design of the device is optimized for

excellent frequency response at a higher frequency

spectrum of the signals. The silicon signal traces and

switch network of the TMUXHS4446 are matched for

best intra-pair skew performance.

The TMUXHS4446 has an extended industrial

temperature range (?40°C to 105°C) designed for

many rugged applications, including industrial and

high reliability use cases.
