TIP Power Amplifier Output.
Battery Ground - To be connected to zero potential. All loop current and longitudinal current flow from this ground.
Internally separate from AGND and SGND but should be connected to the same potential as AGND & SGND.
Low Battery Supply Connection.
High Battery Supply Connection.
Selects between high and low battery, with a logic “1” selecting the high battery and logic “0” the low battery.
TTL Mode Control Input - MSB.
TTL Mode Control Input.
TTL Mode Control Input - LSB.
Detector Output - This TTL output provides on-hook/off-hook status of the loop based upon the selected operating mode.
The detected output will either be switch hook or ring trip.
Non-Inverting Ringing Signal Input - Analog input for driving 2-wire interface while in Ring Mode.
Inverting Ringing Signal Input - Analog input for driving 2-wire interface while in Ring Mode.
Transmit Output Voltage - AC couples to CODEC.
Transmit Output Voltage - AC couples to CODEC.
Analog Ground Reference. This pin should be externally connected to BGND.
An External Capacitor on this pin sets the polarity reversal time.
Non-Inverting Analog Receive Voltage - 4-wire analog audio input voltage.
Inverting Analog Receive Voltage - 4-wire analog audio input voltage.
Connection Terminal for impedance matching programming resistor
Connection Terminal for high pass filter capacitor and impedance matching components.
Connection Terminal for high pass filter capacitor and impedance matching components.
Transient Current Limit Programming Resistor Connection Terminal.
Positive Voltage Power Supply, +5V +/-5%.
DC Biasing Filter Capacitor - Positive Terminal.
DC Biasing Filter Capacitor - Negative Terminal.
Ring Trip Filter Network Connection Terminal.
Loop Current Limit programming resistor connection terminal.
Switch Hook Detection threshold programming resistor connection terminal.
RING Power Amplifier Output.
