3 Description
The TUSB546A-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 TUSB546A-DCI provides several levels of
receive linear equalization to compensate for inter
symbol interference (ISI) due to cable and board
trace loss. Operates on a single 3.3-V supply and
comes in a commercial temperature range and
industrial temperature range.
