Function
Ground
Ground
The S/UNI is configured for the 8 bit FIFO interface,
TxDat[7:0] corresponds to a cell byte.
TxDat[7] corresponds to bit 1, the first bit received.
TxDat[0] corresponds to bit 8, the last bit received.
+5 Volts

Ground
Transmit data bus (TxDat[7:0]) odd parity. Not
Used
Transmit start of cell indication. Identifies the first
byte (word) of a cell on inputs TxDAT[7:0]
Ground
Ground
Active low signal from the PHY to ATM layer,
asserted by the PHY layer 4 cycles before it is no
longer able to accept transmit data.
Active low signal from the ATM layer to the PHY
layer, asserted by the ATM layer when it has a full
cell to transmit.
Ground
Ground
The transmit transfer/synchronization clock
provided by the ATM to the PHY layer for
synchronizing transfers on the TxDATA bus.
(nominally at 20 MHz).
Transmit Reference. Input for the purposes of
synchronization (e.g. 8 KHz frame marker or
SONET frame indicator). Not Used
