Detailed Design Procedure

The TUSB522P differential receivers and transmitters have internal BIAS and termination. Due to this, the TUSB522P must be connected to the USB Host and receptacle through ac-coupling capacitors. In this example, as depicted in Figure 8-2, 100 nF capacitors are placed on TX2P, TX2N, RX1P, RX1N, TX1P and TX1N. No ac-coupling capacitors are placed on the RX2P and RX2N pins because it is assumed the device downstream of the TUSB522P will have ac-coupling capacitors on its transmitter as defined by the USB 3.1 specification. The system designer may desire to support short to VBUS protection. If this is the case, then a 330 nF ac-coupling capacitor should be placed on RX2P/N pins.
