General 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 telecommunications 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 limiting adjustable to max 65 mA.

Overview

Preliminary February 2000 PBL 386 61/2 Subscriber Line Interface.

Key Features

  • Selectable overhead voltage principle.
  • All adaptive: The overhead voltage follows 0.6 VPeak < signals < 6.2 VPeak.
  • Semi adaptive: The overhead voltage follows 3.1 VPeak < signals < 6.2 VPeak.
  • Metering 2.2 Vrms.
  • High and low battery with automatic switching.
  • Battery supply as low as -10 V.
  • Only +5 V in addition to GND and battery (VEE optional).
  • 39 mW on-hook power dissipation in active state.
  • Long loop battery f.
