Texas Instruments' TUSB564 is a VESA USB Type-C Alt Mode redriving switch supporting USB 3.1 data rates up to 5 Gbps and display port 1.4 Gbps up to 8.1 Gbps for upstream facing port (sink). The device is used for UFP_D pin assignments C, D, and E from the VESA display port alt mode on USB Type-C standard.

The TUSB564 provides several levels of receive linear equalization to compensate for intersymbol 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.

For a sink application, the TUSB564 enables the system to pass both transmitter compliance and receiver jitter tolerance tests for USB 3.1 Gen1 and display port 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 redrive.

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 USB 3.1 compliant.
