3 Description
The TUSB546-DCI is a VESA USB Type-C™ Alt
Mode redriving switch supporting USB 3.1 data rates
up to 5 Gbps and DisplayPort 1.4 up to 8.1 Gbps for
downstream facing port (Host). The device is used for
configurations C, D, E, and F from the VESA
DisplayPort Alt Mode on USB Type-C Standard
Version 1.1. This protocol-agnostic linear redriver is
also capable of supporting other USB Type-C Alt
Mode interfaces.
The TUSB546-DCI provides several levels of receive
linear equalization to compensate for cable and board
trace loss due to inter symbol interference (ISI).
Operates on a single 3.3 V supply and comes in a
commercial temperature range and industrial
temperature range.
