WIDEBAND FM/FSK IF RECEIVER S1T8531 INTRODUCTION 16-SOP-225 The S1T8531 is a wideband FM / FSK receiver designed for wideband FSK data and analog FM applications. It is fabricated using Samsung’s ASP5HB 0.5um advanced BiCMOS process. The S1T8531 contains high gain IF amplifier with received signal strength indicator (RSSI), a wideband FM quadrature demodulator, a baseband filter amplifier and a high speed data slicer with sample & hold function. The IF amplifier has 100dB small signal gain and.
