The recommendation is to connect the USB supplies VDDA_CORE_USB (USB0 and USB1 core supply), VDDA_1P8_USB (USB0 and USB1 1.8V analog supply), and VDDA_3P3_USB (USB0 and USB1 3.3V analog supply) to the recommended power supply rails in the processor-specific data sheet.
Connect USBn_DM (n = 0-1) and USBn_DP (n = 0-1) signals directly (without any series resistors or capacitors). Route USBn signals with traces that does not include any stubs or test points.
Connect a resistor between USBn_RCALIB (n = 0-1) (close to processor) and VSS. Refer to the processor-specific data sheet for recommended resistor value and tolerance.
