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 intersymbol
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.
