PBL38661-2 Description
The PBL 386 61/2 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated circuit for use in Central Office, MUX and other telemunications equipment. The PBL 386 61/2 has been optimized for low total line interface cost and a high degree of flexibility in different applications. The PBL 386 61/2 emulates a transformer equivalent dc-feed, programmable between 2x25 Ω and 2x900 Ω, with short loop current...
