The Si3241 includes internal ringing generation to eliminate centralized ringers and ringing relays. On-chip subscriber loop and audio testing allows remote diagnostics and fault detection with no external test equipment or relays. The Quad ProSLIC devices operate from a single 3.3 V supply and interface to standard PCM/SPI or GCI bus digital interfaces. The Si3206/3 linefeed interface IC performs all high-voltage functions and operates from a 3.3 V supply as well as three battery supplies up to –135/–110 V. The Quad ProSLIC devices are available in a 100-pin thin quad flat package (TQFP), and the Si3206/3 is available in a thermally- enhanced 48-pin thin quad flat package (TQFP) or 40-pin quad flat no-lead (QFN) package. Features - Performs all BORSCHT functions - Ideal for applications up to 20 kft (6 km) - Internal adaptive balanced ringing to –135 VPK (Si3206) and –110 VPK (Si3203) - Internal unbalanced ringing - Power offloading - Low power consumption - 2.5 Vrms pulse metering (12/16 kHz) - Software programmable parameters: - Ringing frequency, amplitude, cadence, and wave- shape - Two-wire ac impedance - Transhybrid balance - DC current loop feed (10–50 mA) - Loop closure and ring trip thresholds - Ground key detect threshold - Power alarms - Automatic switching of up to three battery supplies - On-hook transmission - Loop or ground start operation - Smooth polarity reversal - DTMF decoder - Dual tone generators - Caller ID generator - A-Law/µ-Law companding, linear PCM - PCM and SPI bus digital interfaces with program- mable interrupts - GCI/IOM-2 mode support - 3.3 V operation - GR-909/844 loop diagnostics - Audio diagnostics with loopback - Pb-free/RoHS compliant packages Applications - Digital loop carrier (DLC) line cards - Central office (CO) line cards - Integrated voice and data (IVD) line cards - Private Branch Exchange (PBX) systems - Key telephone systems - Optical networking terminals (ONT) - VoIP Gateways |
