Interface Description

Type Descriptions

8mA

O FET Control Signal.

The pin is used to control FET for 3.3V to 1.8V regulator.

Analog TX Resistor. Add 1.1K %1 resister to GND.

Analog Analog Reference Voltage.

I, RC Input for Power On reset. Reset input pin.

SCHE

I, 25M Crystal Input. 25M Crystal Input. Variation is limited to

Analog +/- 50ppm.

O, 25M Crystal Output. When connected to oscillator, this pin

Analog should left unconnected.

I, Configuration of Port 4 MII Mode

PU CFG0 P4TYPE Description

0 00 5 Port and 1 MII interface

0 01 4 Port and 2 MII(MAC) interface

1 xx 4 Port and 1 MII(MAC) and 1 MII(PCS)

I/O, Management Data. MDIO transfers management data in

8mA and out of the device synchronous to MDC.

PU

I, Management Data Reference Clock. A non-continuous

SCHE clock input for management usage. ADM7001/T will use

this clock to sample data input on MDIO and drive data onto

MDIO according to rising edge of this clock.

I, TEST Value.

PD At normal application connect to GND.
