FEATURES V2.0October 2002 Advance data Sheet FULLY FEATURED P S T N IN T E R F A C E - A highly featured PSTN Interface (COIC, FXO, DAA, Trunk Interface) in a single DIL or 12mm high SIL device. - +5V or +3.3V supply. - Transformer isolation providing high mon mode rejection (CMRR) for use in un-grounded systems. - Highly integrated with on board loop switch and integral diode bridge. - Loop start circuit, ringing detect and loop current detection. Parallel phone detect. - Tip-ring polarity reversal detect (for Caller Line ID and remote metering) and on-hook reception. - Meets requirements of EN60950/UL1950, and FCC Pt68. Low cost power cross protection. - Programmable d.c. mask, line and network impedances. - Silver Tele “design-in” assistance. TIP RING V IN TRUNK V OUT Control and Supervision DESCRIPTION The Ag2120 is a self-contained highly integrated PSTN Interface Circuit in a single SIL or DIL Module. In addition to the features listed, the Ag2120 allows flexible programming of many functions, including the dc voltage mask and impedances. The Ag2120 meets international safety and regulatory requirements. The device requires a minimum of external ponents and has been specified for ease of use, to reduce time to market. The Ag2120 is designed for all applications, including those where there is a high level of mon mode interference, such as PABX, long loop applications and systems without a ground. © Silver Tele 2002 V2.0 October 2002 Advance Data Sheet F U L L Y F E A T U R E D P S T N IN T E R F A C E Ordering Information Ag2120D Ag2120S Fully featured Trunk in DIL package Fully featured Trunk in SIL package Silver TELE Figure 1: Ag2120D - DIL Packaging Format Silver T E L EC O M Figure 2: Ag2120S - SIL Packaging Format V CC DMa DMb Power Management 2-4 Wire Converter Tip Ring Line Termination & Loop Switch Z T1 Z T2 Zb V TR Vref V out V in RS LC LSC F/R Supervision Anode Gate...
