USB3250 General Description
The GT3200 and USB3250 are USB2.0 physical layer transceiver (PHY) integrated circuits. SMSC's proprietary technology results in low power dissipation, which is ideal for building a bus powered USB2.0 peripheral. The PHY can be configured for either an 8-bit unidirectional or a 16-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 for the USB2.0 Transceiver is internal. Internal 5.25V short circuit protection of DP and DM lines is provided for USB compliance.
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.
