Current Shunt Control Output
This N-channel open drain output controls the external high power shunt
transistor for the modulation of the line voltage and for shorting the line
during make period of pulse dialling.
Positive Voltage Supply
This is the supply pin for the circuit.
Negative Power Supply
Melody Output
Pulse Density Modulated output of the melody generator for tone ringer. At
high impedance when not active.
Frequency Comparator Input
This is a Schmitt trigger input for ring frequency discrimination. Disabled
during off-hook.
Hook Switch Input and Dial Pulse Output
This is an I/O that is pulled high by the hook switch when off- hook. An open
drain pulls it low during break periods of pulse dialling and flash.
Oscillator Input
Oscillator pin for Xtal or ceramic resonator (3.58 MHz). Recommended part
is the Murata CSA3.5MG312AM.
Line Loss Compensation
Select pin for the loss compensation.
OPEN = None V
DD
= 45-75mA V
DD
= 20-50mA
Repetition Rate
Select pin for repetition rate of melody for the Tone rinser.
Signalling Mode Select Input
