Device Overview

Summary

The Le9530 Dual Ringing SLIC device is a dual-channel device optimized to provide battery feed, ringing, and supervision on voice loops found in short-loop VoIP applications. This device is optimized to interface to the Broadcom BCM3378/3380/3382 and BCM6816 devices, or a similar codec. The Le9530 device operates independently from a single, user-adjusted battery and a +3.3 V VCC per channel. Each channel provides forward and reverse battery feed, voice transmission, power ringing, an ultra low-power scan state, ground start (Tip open), and a disconnect state. A test load switch is also included to support integrated test algorithms.

Additional Features
  • Dual Architecture
    • Two fully independent integrated SLIC channel
    • No impulse noise crosstalk in any operation states to the listening channel in forward or reverse active states
  • Two Power Supplies
    • Single user adjusted battery input per channel
    • 3.3 V for VCC
  • High Voltage Design
    • Meets Comcast Ringing requirements without clipping distortion
    • Robust solution with no damage during extended ringing cycles or switching the ringer on and off
    • Allows use of 50 Ohm protection resistors and lower cost lower current rated protectors
    • Up to -145 V ringing battery Le9530D
    • Up to -100 V ringing battery Le9530C
  • Channel Independent Eight Operating States
    • Scan state for minimal power dissipation
    • Active Forward Battery 25mA DC Current Limit
    • Active Reverse Battery 25mA DC Current Limit
    • Active Forward Battery 40mA DC Current Limit
    • Active Reverse Battery 40mA DC Current Limit
    • Tip Open Ground Start
    • Ringing
    • Disconnect (Default Power Up Mode)
  • Per Channel Ringing Inputs for Optimized Interface to BCM SoC Devices
    • Allows to accept driving signals from per channel voice outputs as well as from PWM outputs
  • Ultra-Low On-Hook Power
  • Loop Start, Ring Trip, and Ground Start Detections
    • Loop closure detection with hysteresis to minimize dial pulse distortion
  • Thermal Shutdown Protection with Hysteresis
  • Test Load Switch
  • Supports integrated test algorithms
