The output of the on-chip Xtal oscillator inverter.

The input to the on-chip Xtal oscillator inverter.

Input to the Ring or Line Polarity Reversal

Detector.

Open-drain output and Schmitt trigger input

forming part of the Ring or Line Polarity Reversal

detector. An external resistor to VDD and a

capacitor to VSS should be connected to RT to

filter and extend the RD input signal.

The output of the on-chip Input Signal Amplifier

and the input to the Bandpass Filter.

The inverting input to the on-chip Input Signal

Amplifier.

The non-inverting input to the on-chip Input

Signal Amplifier.

Negative supply rail (signal ground).

Internally generated bias voltage, held at VDD/2

when the device is not in 'Zero-Power' mode.

Should be decoupled to VSS by a capacitor

mounted close to the device pins.

Input used to select the operating mode. See

section 1.5.1.

A high level on this input selects 'Zero-Power'

mode, a low level enables the VBIAS supply, the

Input Signal Amplifier, the Bandpass Filter and

either the FSK or the Tone Alert circuits

depending on the MODE input.
