USB 2.0 Interface
The SoC has four USB 2.0 ports. Each port consists of a Transceiver differential pair
which is in the 1.0-Volt SUS power well of the SoC.
• USB_DP[3:0], USB_DN[3:0] (Transceiver, Low Voltage Differential)
For USB 2.0 interface electrical specifications, refer to Section 7 of the Universal Serial
Bus Specification, Revision 2.0. The SoC as a USB Host supports:
• Low-Speed Signaling Mode (1.5 Mb/s)
• Full-Speed Mode (12 Mb/s)
• High-Speed Mode (480 Mb/s)
• Full-Speed Mode (12 Mb/s)
• High-Speed Mode (480 Mb/s)
The SoC electrical requirements for the USB differential reference clock inputs are in
.
Other USB Host signals not part of the Universal Serial Bus Specification, Revision 2.0:
• USB_OC0_B (Over Current Indicator input)
