Description
The Si3230 ProSLIC® is a low-voltage CMOS device that provides a multi-functional subscriber line interface ideal for customer premise equipment (CPE) applications. The ProSLIC integrates subscriber line interface circuit (SLIC) and battery generation functionality into a single CMOS integrated circuit.

Features
■ Software Programmable SLIC with codec interface
■ Software programmable internal balanced ringing up to 90 VPK (5 REN up to 4 kft, 3 REN up to 8 kft)
■ Integrated battery supply with dynamic voltage output
    ● On-chip dc-dc converter continuously minimizes power in all operating modes
    ● Entire solution can be powered from a single 3.3 V or 5 V supply
    ● 3.3 V to 35 V dc input range
    ● Dynamic 0 V to –94.5 V output
■ Software programmable linefeed parameters:
    ● Ringing frequency, amplitude, cadence, and waveshape
    ● 2-wire ac impedance
    ● constant current feed (20 to 41 mA)
    ● Loop closure and ring trip thresholds and filtering
■ Software programmable signal generation and audio processing:
    ● DTMF generation and decoding
    ● 12 kHz/16 kHz pulse metering generation
    ● Phase-continuous FSK (caller ID) generation
    ● Dual audio tone generators
    ● Smooth and abrupt polarity reversal
