Data Sheet

Type Description

I

Reference Clock.

25 MHz crystal reference or oscillator input.

Connects to crystal to provide the 25MHz crystal input. If a

25MHz oscillator is used, connect X1 to the oscillator’s output.

The input voltage of this pin should not exceed 1.8V. A voltage

divider formed by 2 resistors is recommended if the output

voltage of oscillator is over 1.8V. Please refer to the Crystal

Specifications in detail.

O

Reference Clock.

25 MHz crystal reference.

I

Hardware reset

Active low.

IP1001 enters reset state when this pin is pulled low.

IPL It is used for scan test only. It should be left open for normal

operation.

O

125M clock output

It is used by external MAC device. This signal is always active

after reset.

Capacitor pin

It should be connected to GND through an external 10uF

capacitor. It is used to stabilize the internal analog power.

I

Band gap Reference

Add an external 6.19kΩ±1% resistor between this pin and

GND. IP1001 utilizes this resistor to set the current source.
