1 CHIP CLP SUBSYSTEM IC S1T8527C INTRODUCTION S1T8527C is a monolithic circuit which can be used in high performance 60MHz MCA type CLP System. The S1T8527C is a subsystem IC for FM / FSK receiving systems and a complete one chip FM / FSK receiver IC for 60MHz system. It’s feature includes receiving functions for FM / FSK systems, a compander to remove external noise, and PLL ( Phase Lock Loop ) of channel selection which blocks surrounding frequency interference. The S1T8527C can be used with a wide range of FM / FSK VHF bandwidth systems, including cordless phone, and the narrow band voice and data sending / receiving systems. To make applications easily and simply, peripheral parts are minimized. 48−QFP−1010E FEATURES • • • • • • • Operating voltage range: 2.0V — 5.
