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.

Key Features

• Selectable overhead voltage principle

– All adaptive: The overhead voltage follows 0.6 V Peak < signals < 5 VPeak.

– Semi adaptive: The overhead voltage follows 2.5 VPeak < signals < 5 V Peak.

• 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 tracks VBat for maximum line voltage

• 44V open loop voltage @ -48V battery feed

• Constant loop voltage for line leakage <5 mA

• On-hook transmission

• Full longitudinal current capability during on-hook

• Programmable loop & ring-trip detector threshold

• Ground key detector

• Analog temperature guard

• Silent polarity reversal

• Integrated Ring Relay Driver
