8 / 16 page PBL 386 21/2 8 Refer to figure 7. PLCC Symbol Description 1 PTG Prog. Transmit Gain. Left open transmit gain = 0.0 dB, connected to AGND transmit gain = -6.02 dB. 2 RRLY Ring Relay driver output. The relay coil may be connected to maximum +14V. 3 HP Connection for High Pass filter capacitor, C HP. Other end of CHP connects to TIPX. 4NC No internal Connection. 5 RINGX 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). 6 BGND Battery Ground, should be tied together with AGND. 7 TIPX 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). 8 VBAT Battery supply Voltage. Negative with respect to GND. 9 VBAT2 An optional second (2) Battery Voltage connects to this pin via an external diode. 10 PSG Programmable Saturation Guard. The resistive part of the DC feed characteristic is not used for PBL 386 21/2, RSG = 0 Ω. 11 NC No internal Connection. 12 LP Connection for Low Pass filter capacitor, C LP. Other end of CLP connects to VBAT. 13 DT 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. 14 DR 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. Pin Description Figure 7.
