Function
UTOPIA Receive Data Bus
Byte-wide data driven from PHY to ATM
layer. RxData[7] is the MSB.
UTOPIA Receive Odd Parity Bit
Odd parity for RXDAT[0:7] driven by the
PHY layer.
UTOPIA Receive Start-of-Cell
Active high signal asserted by the PHY layer
when RXDAT[0:7] contains the first valid
byte of a cell.
UTOPIA Receive Cell Available
Slave: RXCLAV is an active high signal
asserted by the PHY layer to indicate that it
has data available for transfer to the ATM
layer.
Master: RXCLAV is an active high signal
asserted by the ATM layer to indicate that it
has data available for transfer to the PHY
layer.
UTOPIA Receive Clock
Transfer/synchronization clock from the
ATM layer to the PHY layer for
synchronizing transfers on RXDAT[0:7].
UTOPIA Receive Enable
Slave: Active low signal asserted by the
ATM layer to indicate that RXDAT[0:7] and
RXSOC will be sampled at the end of the
next cycle.
Master: Active low signal asserted by the
PHY layer to indicate that RXDAT[0:7] and
RXSOC will be sampled at the end of the
next cycle.
