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 package.
The USB3280 is an industrial temperature USB 2.0 physical layer transceiver (PHY) inte grated 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 da ta, the PHY serializes data and generate s SYNC and EOP fi eld s. It al so perfo rms
needed bit stuffing and NRZI encodin g. Likewise, while receiving data, the PHY de-serializes incoming
data, stripping SYNC and EOP fields and performs bit un-stuffing and NRZI decoding.
