Universal Serial Bus (USB)
6.4.8.2 USB 3.0 PHY
For USB 3.0, FX3 has a separate, dedicated USB 3.0 transceiver with a PIPE 3-compliant interface directly connected to the
back-end USB 3.0 function controller. It includes these features:
■ Dedicated, dual-simplex differential pairs for data transmit (SSTX+/-) and receive (SSRX+/-)
■ Sideband functionality (such as reset, wake) with Low Frequency Periodic Signaling (LFPS)
■ USB hot plug with receiver termination for connect/disconnect detection
■ 5-Gbps SuperSpeed data transmission rate over 3-meter USB 3.0 cable
■ Integrated transmitter, receiver, spread-spectrum clock (SSC) generation, PLL and ESD protection
■ Full support for USB 3.0 test modes
6.5 UIB Top-Level Register Interface
FX3 features a common top-level register interface shared among all UIB functional blocks, as shown in the following code.
Some functional blocks may also have their own specific register interface, which is described in their respective sections.
