Hi-Speed USB Transceiver with 1.8V ULPI Interface - 13MHz Reference Clock

General Description

The USB3319 is a highly integrated Hi-Speed USB 2.0 Transceiver (PHY) that supports systems

architectures based on a 13MHz reference clock. It is designed to be used in both commercial and

industrial temperature applications.

The USB3319 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 USB3319 also provides

USB UART mode and USB Audio mode.

USB3319 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 USB3319 uses SMSC’s “wrapper-less” technology to implement the ULPI interface. This “wrapper-

less” 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.
