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.
