Description
TXPAUSEADD[2:0] is the port selection address
for pause frame insertion.
TX Pause Interface Strobe.
Description
Transmit Disable:
TX_DISABLE_0:3 outputs disable the Optical
Module Interface transmitter. An external pull-up
resistor usually resident in an optical module is
required for proper operation.
NOTE: These signals are multiplexed with the
TXD[4]_n bits of the GMII Interface
NOTE: *Dual-mode I/O
Normal operation: Open drain output
Boundary Scan Mode: Standard CMOS
output
MOD_DEF_0:3 inputs determine when an
Optical Module Interface is present.
NOTE: These signals are multiplexed with the
RXD[4]_n bits of the GMII interface.
RX_LOS_0:3 inputs determine when the Optical
Module Interface receiver loses synchronization.
NOTE: These signals are multiplexed with the
RXD[6]_n bits of the GMII interface.
TX_FAULT_0:3 inputs determine an Optical
Module Interface transmitter fault.
NOTE: These signals are multiplexed with the
RXD[5]_n bits of the GMII Interface.
Receiver Loss of Signal Interrupt.
RX_LOS_INT is an open drain interrupt output to
signal an RX_LOS condition.
NOTE: An external pull-up resistor is required
for proper operation.
NOTE: *Dual-mode I/O
Normal operation: Open drain output
Boundary Scan Mode: Standard CMOS
output
