Non-inverting Input of the gain adjustable op amp.
Inverting Input of the gain adjustable op amp.
Gain Select Output of the gain adjustable op amp.
Select the op amp gain by adjusting the resistor ratio in the feed-back resistor network.
Reference Voltage.
This output is used to bias the input op amp. It is typically VCC/2.
Capacitor Connector.
A 0.1 F decoupling capacitor should be connected between this pin and GND.
Trigger Input.
This is a Schmitt trigger input used for ring detection and line reversal detection.
Trigger Resistor and Capacitor Connector.
This pin is connected to VCC and GND through resistor and capacitor. The RC value
decides the time delay from TRIGIN going inactive (low) to TRIGOUT becoming inactive
(high). See Fig.6 for reference.
Trigger Output.
This is a Schmitt trigger buffer output indicating the detection of line reversal and/or ringing.
Serial FSK Interface MODE Select.
A low level on this pin sets the interface to mode '0', while a high level sets it to mode '1'.
Oscillator Input.
A 3.579545 MHz crystal or ceramic resonator should be connected between this pin and
the OSCOUT. It can also be driven by an external clock source.
Oscillator Output.
A 3.579545 MHz crystal or ceramic resonator should be connected between this pin and
and OSCIN. When OSCIN is driven by an external clock, this pin should be left floating.
Ground.
Test Mode. Must be connected to GND for normal operation.
