For what is the pin hsusb1_clk? How connect it with USB3317 CLKOUT or REFCLK? I cannot find any USB PHY for 60Mhz clock frequency.

    The hsusb1_clk pin is a 60MHz ULPI clock output.  

     

    The ULPI specification provides an option for ULPI USB transceivers to support clock input mode.  

     

    The hsusb1 port on AM35x and AM37x only operates in clock out mode which requires UPLI USB transceivers capable of operating in clock input mode.

     

    The TUSB1210 is the recommended UPLI USB transceiver for connecting to the AM35x and AM37x devices.
