Si3219x: ProSLIC® Single FXS SolutionProSLIC® Single-Channel FXS SolutionsThe Si3219x Single FXS ProSLIC® devices implement a complete foreign exchangestation (FXS) telephony interface solution in a single package that conforms to allrelevant global specifications. The Si3219x ProSLIC ICs operate from a 3.3 V supplyand have a 3-wire ISI digital interface with 1.8 to 3.3 V I/O. The Si3219x devices aredesigned to operate with a capacitive boost tracking battery supply for lower power,cost, and footprint than other tracking supplies in the industry. Self-testing and metallicloop testing (MLT) are facilitated by the built-in DSP, monitor ADC, and test load. Thedevices are available with wideband audio for better-than-PSTN voice quality and DTMFdetection. The Si3219x devices are available in a 4 x 6 mm, 38-pin QFN package.Applications:• VoIP Gateways and Routers• xDSL IADs• Optical Network Terminals/Units (ONT/U)• Analog Terminal Adapters (ATA)• Cable eMTA• Wireless Fixed Terminals (WFT)• Wireless Local Loop (WLL)• WiMAX CPEKEY FEATURES• Complete FXS solution in a single 4 x 6mm package• Performs all BORSCHT functions• Ideal for short- or medium-loopapplications• Ultra-low power consumption• Patented low-power ringing• Adaptive ringing• Dynamic overhead control• Ringing current limiting• Simplified configuration and diagnostics• Supported by ProSLIC API• Audio diagnostics with loopback• Integrated test load• Global programmability• Wideband voice support• On-hook transmission• Loop or ground start operation• Smooth polarity reversal• A-Law/µ-Law companding, linear PCM• Flexible integrated tracking dc-dccontroller supporting patent-pending low-cost capacitive boost configuration• Software-programmable parameters:• Ringing frequency, amplitude, cadence,and waveshape• Two-wire ac impedance• Transhybrid balance• DC current loop feed (10–45 mA)• Loop closure and ring trip thresholds• Ground key detect threshold• Pulse metering• DTMF generation• DTMF detection (Si32193)• 3.3 V operation• Support for 1.8 V I/O• Maximum battery up to –100 V• Pb-free/RoHS-compliant packaging• 3-wire Integrated Serial Interface (ISI)RINGTIPDSPDTMF
