WIDEBAND FM/FSK IF RECEIVER

S1T8531

1

INTRODUCTION

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 2MHz through

40MHz bandwidth. The wideband FM quadrature demodulator has

demodulation bandwidth greater than 1MHz.

The baseband filter amplifier is a wideband buffer and it can be

configured as a second-order sallen-key low pass filter. The data slicer is a comparator that is designed to square

up the data signal with data rates up to 2Mbps.
