PBL38611-2 - Subscriber Line Interface Circuit

Datasheet Summary

Description

The PBL 386 11/2 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated circuit for use in DAML, FITL and other telecommunications equipment.

The PBL 386 11/2 has been optimized for low total line interface cost and a high degree of flexibility in different applications.

Features

  • Selectable overhead voltage principle.
  • All adaptive: The overhead voltage follows 0.6 VPeak < signals < 5 VPeak.
  • Semi adaptive: The overhead voltage follows 2.5 VPeak < signals < 5 VPeak.
  • Metering 1.6 Vrms.
  • High and low battery with automatic switching.
  • Battery supply as low as -10V.
  • Only +5V in addition to GND and battery (VEE optional).
  • 35 mW on-hook power dissipation in active state.
  • Long loop battery feed tra.

February 2000 PBL 386 11/2 Subscriber Line Interface Circuit Description The PBL 386 11/2 Subscriber Line Interface Circuit (SLIC) is a 90 V bipolar integrated circuit for use in DAML, FITL and other telecommunications equipment. The PBL 386 11/2 has been optimized for low total line interface cost and a high degree of flexibility in different applications. The PBL 386 11/2 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.
