3 Description

The TUSB1046A-DCI is a VESA USB Type-C™ Alt

Mode redriving switch supporting USB 3.1 data rates

up to 10 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 TUSB1046A-DCI provides several levels of

receive linear equalization to compensate for inter-

symbol interference (ISI) due to cable and board

trace loss. The device operates on a single 3.3-V

supply and comes in a commercial temperature range

and industrial temperature range.
