3 Description
The TUSB5461-Q1 is a VESA® USB Type-C™ Alt
Mode redriving switch supporting USB 3.2 data rates
up to 5Gbps and DisplayPort™ 2.1 up to 8.1Gbps
for downstream facing port (Host). The device is
used for configurations C, D, and E from the VESA®
DisplayPort™ Alt Mode on USB Type-C® standard.
This protocol-agnostic linear redriver is also capable
of supporting other USB Type-C® Alt Mode interfaces
such as HDMI® Alt Mode.
The TUSB5461-Q1 also incorporates an adaptive
receiver equalization (AEQ) feature that can
automatically find the best ISI compensation setting
between the USB device and the TUSB5461-Q1. The
AEQ finds the best setting, therefore interoperability
between a USB Host and USB Device is vastly
improved. The TUSB5461-Q1 operates on a single
3.3V supply and comes in a Automotive Grade 2
temperature range.
