Product data sheet
7.1 ULPI interface controller
7.2 USB data serializer and deserializer
7.3 Hi-Speed USB (USB 2.0) ATX
The ISP1507 provides a 12-pin interface that is compliant with UTMI+ Low Pin Interface
(ULPI) Specification Rev. 1.1 . This interface must be connected to the USB link.
The ULPI interface controller provides the following functions:
For more information on the ULPI protocol, see
The USB data serializer prepares data to transmit on the USB bus. To transmit data, the
USB link sends a transmit command and data on the ULPI bus. The serializer performs
parallel-to-serial conversion, bit stuffing and NRZI encoding. For packets with a PID, the
serializer adds a SYNC pattern to the start of the packet, and an EOP pattern to the end
of the packet. When the serializer is busy and cannot accept any more data, the ULPI
interface controller deasserts NXT.
The USB data deserializer decodes data received from the USB bus. When data is
received, the deserializer strips the SYNC and EOP patterns, and then performs
serial-to-parallel conversion, NRZI decoding and discarding of stuff bits on the data
payload. The ULPI interface controller sends data to the USB link by asserting DIR, and
then asserting NXT whenever a byte is ready. The deserializer also detects various
receive errors, including bit stuff errors, elasticity buffer underrun or overrun, and
byte-alignment errors.
The Hi-Speed USB ATX block is an analog front-end containing the circuitry needed to
transmit, receive and terminate the USB bus in high-speed, full-speed and low-speed, for
USB peripheral, host and OTG implementations. The following circuitry is included:
