Signal
Description
Pin No.
Name
Type
1
XTALN
O/P
The output of the on-chip Xtal oscillator inverter.
2
XTAL
I/P
The input to the on-chip Xtal oscillator inverter.
3
RD
I/P (S)
Input to the Ring or Line Polarity Reversal
Detector.
4
RT
BI
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.
5
AOP
BI
The output of the on-chip Input Signal Amplifier
and the input to the Bandpass Filter.
6
INV
I/P
The inverting input to the on-chip Input Signal
Amplifier.
7
NINV
I/P
The non-inverting input to the on-chip Input
Signal Amplifier.
8
VSS
Power
Negative supply rail (signal ground).
9
VBIAS
O/P
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.
10
MODE
I/P (S)
Input used to select the operating mode. See
section 1.5.1.
11
ZP
I/P (S)
A high level on this input selects 'Zero-Power'
mode, a low level enables the Input Signal
Amplifier, the Bandpass Filter and either the FSK
or the Tone Alert circuits depending on the
MODE input.
