Product data sheet
If a crystal is attached or a clock is driven into the XTAL1 pin, the ISP1504 will drive a
60 MHz clock out from the CLOCK pin when DIR deasserts. This is shown as CLOCK in
Figure
The recommended power-up sequence for the link is as follows:
The ULPI interface is ready for use.
1. The link waits for 1 ms, ignoring all the ULPI pin status.
2. The link may start to detect DIR status level. If DIR is detected as LOW for three clock
cycles, the link may send a RESET command.
