The TMUXHS4446-Q1 is a high-speed bidirectional passive crosspoint switch or crossbar (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-Q1 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-Q1 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-Q1 are matched for best intra-pair skew performance.

The TMUXHS4446-Q1 has an extended industrial temperature range (−40°C to 125°C) designed for many rugged applications, including industrial and high reliability use cases.
