PBL38665-2 - Subscriber Line Interface Circuit

General Description

The PBL 386 65/2 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated circuit for use in DLC, Central Office and other telecommunications equipment.

The PBL 386 65/2 has been optimized for low total line interface cost and a high degree of flexibility in different applications.

Key Features

  • Selectable overhead voltage principle.
  • All adaptive: The overhead voltage follows 0.6PeakV < signals < 6.2VPeak.
  • Semi adaptive: The overhead voltage follows 3.1VPeak < signals < 6.2VPeak.
  • 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 feed t.

Preliminary May 2000 PBL 386 65/2 Subscriber Line Interface Circuit Description The PBL 386 65/2 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated circuit for use in DLC, Central Office and other telecommunications equipment. The PBL 386 65/2 has been optimized for low total line interface cost and a high degree of flexibility in different applications. The PBL 386 65/2 emulates a transformer equivalent dc-feed, programmable between 2x25 Ω and 2x900 Ω, with short loop current limiting adjustable to max 65 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 components or external control.
