 USB3280
Hi-Speed USB Device PHY with UTMI Interface
 General
Description
The USB3280 provides the Physical Layer (PHY) interface to a USB 2.0 Device Controller. The IC is
available in a 36-pin lead-free RoHS compliant QFN.
The USB3280 is an industrial temperature USB 2.0 physical layer transceiver (PHY) integrated circuit. SMSC's proprietary technology results in low power dissipation, which is ideal for building a bus powered USB 2.0 peripheral. The PHY uses an 8-bit bidirectional parallel interface, which complies with the USB Transceiver Macrocell Interface (UTMI) specification. It supports 480Mbps transfer rate, while remaining backward compatible with USB 1.1 legacy protocol at 12Mbps.
All required termination and 5.25V short circuit protection of the DP/DM lines are internal to the chip.
The USB3280 also has an integrated 1.8V regulator so that only a 3.3V supply is required.
While transmitting data, the PHY serializes data and generates SYNC and EOP fields. It also performs
needed bit stuffing and NRZI encoding. Likewise, while receiving data, the PHY de-serializes incoming
data, stripping SYNC and EOP fields and performs bit un-stuffing and NRZI decoding.
