PBL38621-2 Datasheet | Ericsson

June 1999 PBL 386 21/2 Subscriber Line Interface Circuit Description The PBL 386 21/2 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated circuit for use in DAML, FITL and other telemunications equipment. The PBL 386 21/2 has been optimized for low total line interface cost and a high degree of flexibility in different applications. The PBL 386 21/2 has constant current feed, programmable to max. 30 mA. A second lower battery voltage may be connected to the device to reduce short loop power dissipation. The SLIC automatically switches between the two battery supply voltages without need for external ponents or external control. The SLIC incorporates loop current,...
