Output
10Base-T / 100Base-TX Select.
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.
10TCSR
15
Input
10M Transmit Current Set Resistor.
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 Section 10.3,
100TCSR
16
Input
100M Transmit Current Set Resistor.
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 Section 10.3,
REF_IN
47
Input
(Frequency) Reference Input.
This pin is connected to a 25-MHz oscillator. For a tolerance, see
REF_OUT
46
Output
(Frequency) Reference Output.
This pin is used with a crystal.
RESETn
22
Input
(System) Reset (Active Low).
When the signal on this active-low pin is logic:
– Low, the ICS1893AF is in hardware reset.
– High, the ICS1893AF is operational.
