In the TUSB1210EVM User Guide, Figure 3 is as follows: Input signal (ULPI interface) termination resistor, why use 22Ω?
Can you help me to see if usb.pdfis reasonable and what needs to be modified?
Thanks a lot.

Please help review the the schematic we designed.0675.usb.pdf
22 ohm is not required.
in your schematic, VDD15 and VDD33 don't need external supply
