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.
