AG1171-S

AG1171-S is a single subscriber line interface circuit (SLIC) in a 14-pin single in line (SIL) format. The combination of features and packaging offers extremely efficient use of board area, saving significant system size and cost, minimising time to market for telephony systems developers. The Ag1171 has been designed to work with loop lengths of typically 1.0km (470R including telephone). The Ag1171 has integral dc/dc converter and ringing generation thus providing all the line powering requirements from a single supply. The Ag1171 requires a minimum of external components, making it ideal for low line count, short loop length applications, such as WLL terminal (WLL), fixed cellular terminals (FCT), fixed wireless terminals (FWT) and internet telephony (VoIP).
