Si3219x: ProSLIC Single FXS Solution ProSLIC Single-Channel FXS Solutions KEY FEATURES The Si3219x Single FXS ProSLIC devices implement a complete foreign exchange Complete FXS solution in a single 4 x 6 station (FXS) telephony interface solution in a single package that conforms to all mm package relevant global specifications. The Si3219x ProSLIC ICs operate from a 3.3 V supply Performs all BORSCHT functions and have a 3-wire ISI digital interface with 1.8 to 3.3 V I/O. The Si3219x devices are Ideal for short- or medium-loop designed to operate with a capacitive boost tracking battery supply for lower power, applications cost, and footprint than other tracking supplies in the industry. Self-testing and metallic loop testing (MLT) are facilitated by the built-in DSP, monitor ADC, and test load. The Ultra-low power consumption devices are available with wideband audio for better-than-PSTN voice quality and DTMF Patented low-power ringing detection. The Si3219x devices are available in a 4 x 6 mm, 38-pin QFN package. Adaptive ringing Dynamic overhead control Ringing current limiting Applications: Simplified configuration and diagnostics VoIP Gateways and Routers Supported by ProSLIC API xDSL IADs Audio diagnostics with loopback Optical Network Terminals/Units (ONT/U) Integrated test load Analog Terminal Adapters (ATA) Global programmability Cable eMTA Wideband voice support Wireless Fixed Terminals (WFT) On-hook transmission Loop or ground start operation Wireless Local Loop (WLL) Smooth polarity reversal WiMAX CPE A-Law/-Law companding, linear PCM Flexible integrated tracking dc-dc controller supporting patent-pending low- CODECCODECCODEC SLICSLIC cost capacitive boost configuration DTMF and DTMF & TIP LinefeedLinefeed Tone Gen ADC Software-programmable parameters: Tone Gen ADCADC ControlControl FXS Ringing frequency, amplitude, cadence, Caller ID and waveshape RING LinefeedLinefeed DAC DACDAC Host Interface 3-wire ISI MonitorMonitor Two-wire ac impedance Ringing Ringing Transhybrid balance Generator Generator DSPDSP DC current loop feed (1045 mA) Line Diagnostics Line Diagnostics Loop closure and ring trip thresholds Ground key detect threshold Pulse metering PLL DC-DC Controller DTMF generation Si3219x 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) Skyworks Solutions, Inc.
