S E M I C O N D U C T O R HC5520 CO/PABX Polarity Reversal Subscriber Line Interface Circuit Description The HC5520 is a Monolithic Subscriber Line Interface Circuit (SLIC) for Analog Subscriber Line cards in Central Office and PABX switches. The HC5520 provides a comprehensive set of features for these applications including loop reversal, zero crossing ringing relay operation, long loop drive and a mutually independent setting of the receive and transmit gains, and the two wire impedance synthesis. Advanced power management features combined with a small 44 lead MQFP package allow significant board space to be freed up for additional line circuits.
