ZL49200 Datasheet | Zarlink Semiconductor

Features - - - - - - - Transformerless 2 W to 4 W conversion Controls battery feed to line Off-hook and dial pulse detection Ring ground over-current protection Programmable constant current feed -30 V to -72 V battery operation Relay and line driver electronics on board Ordering Information ZL49200MDC 38 Pin SIL -40° C to +85 ° C Trays Description The Zarlink ZL49200 Dual SLIC hybrid provides an interface between a switching system and a subscriber loop with 600 Ω impedance. The functions provided by each SLIC include battery feed, 2 W to 4 W conversion, off-hook and dial pulse detection. All driver electronics are included on the hybrid in order to minimize the number of external ponents required by the user. Loop Length determination table provided on page 9.
