5K

O

This ouput generates reference frequency when it is connected to pin 16 with

external OSC of which frequency is 10.240MHz

I

Base/remote changing. Internal pull down.

V =base,V =remote.

DD

SS

I

The standby pin is uses to save power when no transmit. Internal pull down.

High: transmit and receive active

Low: receive acts only

O

The signal derived from the reference oscillator. 5KHz output.
