USB 3.0 Transceiver and USB 2.0 ULPI PHY

[Figure 2-1, callout 5]
The ZCU106 board uses a Standard Microsystems Corporation USB3320 USB 2.0 ULPI
transceiver at U116 to support a USB connection to the host computer (see
USB cable 3.0 A to A is supplied in the ZCU106 evaluation kit (host computer USB 3.0 A port
to ZCU106 board connector J96). The USB3320 is a high-speed USB 2.0 PHY supporting the
UTMI+ low pin interface (ULPI) interface standard. The ULPI standard defines the interface
between the USB controller IP and the PHY device, which drives the physical USB bus. Use
of the ULPI standard reduces the interface pin count between the USB controller IP and the
PHY device.
