ULPI Timing Specifications
The ULPI interface is fully compliant with the industry standard UTMI+ Low Pin Interface. Control and data timing
requirements for the ULPI pins are given in Table 15. These timings apply to synchronous mode only. All timings are measured
with respect to the clock as seen at the USB_CLKIN pin on the MCF5445x. The ULPI PHY is the source of the 60MHz clock.
NOTE
The USB controller requires a 60-MHz clock, even if using the on-chip FS/LS transceiver
instead of the ULPI interface. In this case, the 60-MHz clock can be generated by the PLL
or input on the USB_CLKIN pin.
