General Description

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 component weight and height result as well.

The PBL 387 10/1 has been optimized for low cost and to require only a minimum of external components.

Key Features

  • 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 de.
