LE9540DUQC Products
The LE9540DUQC 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 with a serial bus to interface to the Broadcom BCM3383/84/85/90 cable SoCs and BCM6818/28/38 PON SoCs. The LE9540DUQC 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.

Feature

  • 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 Ω protection resistors and lower cost lower current rated protectors
    • Two Grades
      • Up to -145 V ringing battery Le9540D
      • Up to -100 V ringing battery Le9540C
  • Channel Independent Eight Operating States
    • Scan state for minimal power dissipation
    • Active Forward Battery (Default Power Up State)
    • Active Forward Battery ICV
    • Active Reverse Battery
    • Tip Open Ground Start
    • Wink
    • 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
