USB2.0 PHY & Controller
The INNO USB 2.0 PHY conforms to the specification of UTMI+ level 3 Revision 1.0 (USB 2.0 Transceiver Macrocell Interface Plus) and has excellent performance. As an integrated high-speed mixed signal circuit, the INNO USB 2.0 PHY supports not only the Low Speed (LS) traffic at 1.5Mbps and Full Speed (FS) traffic at 12Mbps, but also the High Speed (HS) traffic at 480Mbps, while retaining backward compatibility with USB1.1 legacy protocol.
The INNO USB 2.0 PHY is capable to handle the low-level protocol and signaling. In transmitting mode, the PHY serializes data, performs bit stuffing following NRZI encoding when needed, and then generates SYNC and EOP fields. Likewise, in receiving mode, it recovers clock from incoming data, strips the SYNC and EOP fields, performs NRZI decoding with bit un-stuffing when needed and then de-serializes the data. It supports17 modes of operations, including LS, FS, HS, and Device and Host.
The INNO USB 2.0 PHY can be pre-configured as a 30MHz 16-bit or 60MHz 8-bit UTMI data interface, which provides a complete on-chip transceiver physical solution with ESD protection.
