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 0.6 PeakV < signals < 6.2VPeak.

– Semi adaptive: The overhead voltage follows 3.1V Peak < 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 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

? Tip open state with ring ground detector

? Silent polarity reversal

? Line voltage measurement

? -40° C to +85° C ambient temperature range
