This pin acts as an output that indicates the current status of this
pin. In this case, when the signal on this pin is logic:
– Low, this pin indicates 10Base-T operations are selected.
– High, this pin indicates 100Base-TX operations are selected.
A resistor, connected between this pin and ground, is required to
establish the value of the transmit current used in 10Base-T mode.
The value and tolerance of this resistor is specified in
“Recommended Component
A resistor, connected between this pin and ground, is required to
establish the value of the transmit current used in 100Base-TX
mode.
The value and tolerance of this resistor is specified in
“Recommended Component
When the signal on this active-low pin is logic:
– Low, the ICS1893AF is in hardware reset.
– High, the ICS1893AF is operational.
