The Implementation guide SLLA315E says in section 9 that 40MHz crystal is the only supported frequency for TUSB9261, but the schematic drawing Figure 2 in the next section shows a 25MHz crystal. I would prefer to use a 25MHz crystal as we have that part in our design already for ethernet.
I tried to use the 'Submit Documentation Feedback' link at the bottom of the page to report the issue and it didn't seem to work.
