ULPI integration on stm32 mcu clock reference

Hi everyone,

we are moving our design from usb full speed to usb high speed using STM32F76VI.

We want to use the suggested module STULPI01A in order to achieve this.

On datasheet is specified to use a precise reference clock.

Since our application use a gnss receiver which is quite sensitive we opted for using the PLLCLK routed out directly from MCU.

Is this system enough precise or are there any weakness in using this?

 

Thanks.
