Part 9: USB2.0 Host Interface
There are 4 USB2.0 HOST interfaces on the AX7350B FPGA
development board. The USB2.0 transceiver uses a 1.8V, high-speed
USB3320C-EZK chip that supports the ULPI standard interface, and then
expands the 4-way USB HOST interfaces through a USB HUB chip USB2514.
ZYNQ's USB bus interface is connected to the USB3320C-EZK transceiver for
high-speed USB2.0 Host mode data communication. The USB3320C's USB
data and control signals are connected to the IO port of the BANK501 on the
PS side of the ZYNQ chip. The USB interface differential signal (DP/DM) is
connected to the USB2514 chip to extend the four USB ports. Two 24MHz
crystals provide clocks for the USB3320C and USB2514 chips, respectively.
