| SI3245/Si3203 Quad ProSLIC(R) Programmable CMOS SLIC/Codec Description ProSLIC(R) - Software programmable parameters: - 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/-Law companding, linear PCM - PCM and SPI bus digital interfaces with programmable interrupts - GCI/IOM-2 mode support - 3.3 V operation - GR-909/844 loop diagnostics - Audio diagnostics with loopback - Pb-free/RoHS compliant packages The Quad is a series of low-voltage CMOS devices that integrate both SLIC and codec functionality into a single IC to provide a complete four-channel analog telephone interface in accordance with all relevant Telcordia, ITU, and ETSI specifications. The SI3245 supports centralized ringing for long loop and legacy applications. 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 Si3203 linefeed interface IC performs all high-voltage functions and operates from a 3.3 V supply as well as three battery supplies up to -110 V. The Quad ProSLIC devices are available in a 100-pin thin quad flat package (TQFP), and the Si3203 is available in a thermally-enhanced 48-pin thin quad flat package (TQFP) or 40-pin quad flat no-lead (QFN) package.
