19.1.1. Supported PHYS

The USB OTG controller only supports USB 2.0 ULPI PHYs. Only the single data rate (SDR) mode is supported.

PHYs that support LPM mode may not function properly with the USB controller due to a timing issue. It is recommended that designers use the MicroChip USB3300 PHY device that has been proven to be successful on the development board.

Refer to the Cyclone® V Device Datasheet for specific timing information.
