Telecom IC Subscriber Line Interface Concept (SLIC) 48-QFN

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 clippingdistortion
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 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
