Description
Prog. Transmit Gain. Left open transmit gain = 0.0 dB, connected to AGND transmit gain = -6.02 dB.
Ring Relay driver output. The relay coil may be connected to maximum +14V.
Connection for High Pass filter capacitor, C
No internal Connection
The TIPX and RINGX pins connect to the tip and ring leads of the two-wire interface via overvoltage
protection components and ring relay (and optional test relay).
Battery Ground, should be tied together with AGND.
The TIPX and RINGX pins connect to the tip and ring leads of the two-wire interface via overvoltage
protection components and ring relay (and optional test relay).
Battery supply Voltage. Negative with respect to AGND.
An optional second (2) Battery Voltage connects to this pin.
Programmable Saturation Guard. The resistive part of the DC feed characteristic is programmed by a
resistor connected from this pin to VBAT.
No internal Connection
Connection for Low Pass filter capacitor, C
Input to the ring trip comparator. With DR more positive than DT the detector output, DET, is at logic
level low, indicating off-hook condition. The external ring trip network connects to this input.
