S1T8527C

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 — 5.5V Typical supply current: 13.5mA at 3.6V Built−in low battery detection function ( selectable 3.45V, 3.3V, 3.0V, 2.2V, 2.1V ) Built−in speaker amplifier Built−in splatter filter Built−in dual conversion receiver, compander and universal PLL FM Receiver — Complete dual conversion circuit — Excellent input sensitivity (0.7µVrms at 12dB SINAD) Compader — Easy gain control to use external component — Included ALC (Automatic Level Control) circuit — Included Mute logic Universal PLL — RX (TX) divided counter range: 1/16 — 1/16383 — Reference frequency divided counter range: 1/16 — 1/4095 — Lock detector signal output — Serial interface with MCU for controlling each block ORDERING INFORMATION Device S1T8527C...
