... After the Link asserts TXVALID it can assume that the transmission has started when it detects ■ TXREADY has been asserted. The Link must assume that the USB3450 has consumed a data byte if TXREADY and TXVALID ■ are asserted on the rising edge of CLKOUT. The Link must have valid packet information (PID) asserted on the DATA bus coincident with the ■ ...

Page 22

... Each time 8 stuffed bits are accumulated the USB3450 will negate RXVALID for one clock cycle, thus skipping a byte time. When the EOP is detected the USB3450 will negate RXACTIVE and RXVALID. After the EOP has been stripped the USB3450 will begin looking for the next packet. ...

... The USB3450 uses an internal crystal driver and PLL sub-system to provide a clean 480MHz reference clock that is used by the PHY during both transmit and receive. The USB3450 requires a clean 24MHz crystal or clock as a frequency reference. If the 24MHz reference is noisy or off frequency the PHY may not operate correctly ...

Page 27

... There is not a concept of variable single-ended thresholds in the Hi-Speed specification for HS mode. The HS receiver is used to detect Chirp where the output of the HS receiver is always qualified with the Squelch signal. If squelched, the output of the HS receiver is ignored. In the USB3450 alternative to using variable thresholds for the single-ended receivers, the following approach is used. LINESTATE[1:0] ...

Page 28

... The only exception to this is when OPMODE[1:0] is set to state 2 while TXVALID has been asserted (the transceiver is transmitting a packet), in order to flag a transmission error. In this case, the USB3450 has already transmitted the SYNC pattern so upon negation of TXVALID the EOP must also be transmitted to properly terminate the packet. Changing the OPMODE[1:0] signals under all other conditions, while the transceiver is transmitting or receiving data will generate undefined results ...

... This transceiver design pushes as much of the responsibility for timing events on to the Link as possible, and the Link requires a stable CLKOUT signal to perform accurate timing. In case 2 and 3 above, CLKOUT has been running and is stable, however in case 1 the USB3450 is reset from a suspend state, and the internal oscillator and clocks of the transceiver are assumed to be powered down ...

... LINESTATE = J State. The Link must employ a counter (Chirp Count) to count the number of Chirp K and Chirp J states. Note that LINESTATE does not filter the bus signals so the requirement that a bus state must be “continuously asserted for 2.5µs” must be verified by the Link sampling the LINESTATE signals.
