The PBL 387 10/1 ring SLIC (Subscriber Line Interface Circuit) is a bipolar integrated circuit in 90 V technology which replaces the conventional transformer based analog line interface and ringrelay in FITL, WLL, ISDN-TA and other telecommunications equipment with a modern, compact solid state design. Not only is required PCB area reduced, but less componen.
· Ring SLIC eliminates ring relay and conventional ring-generator
· Supports sine wave and trapezoidal ringing
· -85 V battery feed for high voltage ring signal
· On chip automatic battery switch
· Programmable battery feed characteristics
· Battery supply voltage as low as -21 V for power efficient line card designs
· Low on-hook power dissipation, 50 mW @-24 V battery
· Loop current, ring trip and ground key detection functions
· Programmable loop current detector threshold
· Programmable ring trip detector threshold
· Hybrid function with all types of CODEC/filter devices
· Programmable lin.
