The USB3317 is a highly integrated Hi-Speed USB 2.0 Transceiver (PHY) that supports systems architectures based on a 26MHz reference clock. It is designed to be used in both commercial and industrial temperature applications.

The USB3317 meets all of the electrical requirements to be used as a Hi-Speed USB Host, Device,or an On-the-Go (OTG) device. In addition to the supporting USB signaling the USB3317 also provides USB UART mode USB3317 uses the industry standard UTMI+ Low Pin Interface (ULPI) to connect the USB PHY to the  Link. The industry standard ULPI interface uses a method of in-band signaling and status byte transfers between the Link and PHY, to facilitate a USB session. By using in-band signaling and status byte transfers the ULPI interface requires only 12 pins.

The USB3317 uses SMSC's "wrapper-less" technology to implement the ULPI interface. This "wrapperless" technology allows the PHY to achieve a low latency transmit and receive time. SMSC's low latency transceiver allows an existing UTMI Link to be reused by adding a UTMI to ULPI bridge. By adding a bridge to the ASIC the existing and proven UTMI Link IP can be reused.
