Function
PORT1 Duplex
If LEDMODE_1 is 1, this pin indicates both duplex condition and
collision status. When FULL_DUPLEX, this pin will be turned on
for PORT1. When HALF_DUPLEX and no collision occurs, this
pin will be turned off. When HALF_DUPLEX and a collision
occurs, this pin will be off for 100ms and then on for 100ms. If
LEDMODE_1 is 0, this pin indicates collision status. When
HALF_DUPLEX and a collision occurs, this pin will be off for
100ms and turn on for 100ms.
PORT0 Speed LED
Used to indicate speed status of PORT0. When operating in
100Mbps this pin is turned on, and when operating in 10Mbps this
pin is off.
Enable Redundant Capability
During power on reset, value will be latched by ADM6993/X at the
rising edge of RESETL as RDNT_EN. If RDNT_EN is 0,
“REDUNDANT” capability will be disabled. For TS1000
application this pin should have a value of 0.
PORT1 Speed LED
Used to indicate speed status of PORT1. When operating in
100Mbps this pin is turned on, and when operating in 10Mbps this
pin is off.
LED_FIBER_SD
Used to indicate signal status of PORT1 when ADM6993/X is
operating in converter mode.
Enable Snooping Mode
During power on reset, value will be latched by ADM6993/X at the
rising edge of RESETL as SNP_EN. If SNP_EN is 0,
“SNOOPING” capability will be disabled.
PORT[1:0] Link LED
These pins indicate link status. When link status is LINK_UP,
these pins will be turned on for relevant port.
PORT[1:0] Full Duplex LED
These pins indicate current duplex condition of PORT0. When
FULL_DUPLEX, these pins will be turned on for relevant port.
When HALF_DUPLEX these pins will be turned off for relevant
port.
Loop Back Test LED
While performing loop back test this pin is turned on.
