1 CHIP CLP SUBSYSTEM IC
INTRODUCTION
48−QFP−1010E
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.
