The Host/Hub/Function models support all transfer cycles -- control, bulk, interrupt and isochronous; CRC generation and checking, and error generation; NRZI encoding with bit stuffing and error detection via the bus-turnaround timer.
The uPD98408 supports NRZI and 4B/5B encoding/decoding functions and integrates a scrambler/descrambler, line equalizer and clock recovery circuit for each individual port.
The clock and data can be recovered from NRZ and NRZI data streams, and there is no output clock drift in absence of data transitions once lock is acquired.
