8.1 Overview

The TUSB564 is a VESA USB Type-C Alt Mode redriving switch supporting data rates up to 8.1 Gbps for upstream facing port. This device uses 5th generation USB redriver technology. The device is used for UFP pin assignments C and D from the VESA DisplayPort Alt Mode on USB Type-C Standard.

The TUSB564 provides several levels of receive equalization to compensate for cable and board trace loss which if not equalized causes inter-symbol interference (ISI) when USB 3.1 Gen 1 or DisplayPort 1.4 signals travel across a PCB or cable. This device requires a 3.3-V power supply. It comes in a commercial temperature range and industrial temperature range.

For a sink application, the TUSB564 enables the system to pass both transmitter compliance and receiver jitter tolerance tests for USB 3.1 Gen 1 and DisplayPort version 1.4 HBR3. The re-driver recovers incoming data by applying equalization that compensates for channel loss, and drives out signals with a high differential voltage. Each channel has a receiver equalizer with selectable gain settings. The equalization should be set based on the amount of insertion loss in the channels connected to the TUSB564. Independent equalization control for each channel can be set using EQ[1:0], SSEQ[1:0], and DPEQ[1:0] pins.

The TUSB564 advanced state machine makes it transparent to hosts and devices. After power up, the TUSB564 periodically performs receiver detection on the TX pairs. If it detects a USB 3.1 receiver, the RX termination is enabled, and the TTUSB564 is ready to re-drive.

The device ultra-low-power architecture operates at a 3.3-V power supply and achieves Enhanced performance. The automatic LFPS De-Emphasis control further enables the system to be USB3.1 compliant.
