  • Page 3: General Description

    The USB3310 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.
