PBL3796-2 - Subscriber Line Interface Circuit

Description

PBL 3796 is an analog Subscriber Line Interface Circuits (SLICs), which are fabricated in a 75 V bipolar, monolithic process.

The programmable battery feed is resistive with short-loop current limiting.

A switch-mode regulator reduces on-chip power dissipation in the active state.

Features

  • On-chip switch mode regulator to minimize power dissipation.
  • Programmable, resistive battery feed with short-loop current limiting.
  • Line feed characteristics independent of battery variations.
  • Tip-ring polarity reversal function.
  • Tip and ring open circuit state; tip open with ring active state.
  • Detectors: - programmable loop current detector - ring trip detector.
  • Ring and test relay drivers.
  • Line terminating impedance, comp.

April 1997 www.DataSheet4U.com PBL 3796, PBL 3796/2 Subscriber Line Interface Circuit Description PBL 3796 is an analog Subscriber Line Interface Circuits (SLICs), which are fabricated in a 75 V bipolar, monolithic process. The programmable battery feed is resistive with short-loop current limiting. A switch-mode regulator reduces on-chip power dissipation in the active state. In the standby state, power dissipation is further reduced, while still permitting supervisory functions to be active. Tip-ring polarity is reversible without altering SLIC supervisory and voice frequency (vf) functions. Tip and ring outputs can be set to high impedance states. These and other operating states are activated via a parallel, four bit control word.
