TEA5761UK
Low voltage single-chip FM stereo radio
Rev. 01 — 2 August 2006
Product data sheet
1. General description
The TEA5761UK is a single-chip electronically tuned FM stereo radio for low-voltage
applications with fully integrated IF selectivity and demodulation.
The radio is completely adjustment free and only requires a minimum of small and low
cost external components. The radio can tune to the European, US and Japanese
FM bands. The radio does not meet all of the requirements of EN55020; a trade off has
been implemented to achieve the following features.
2. Features
s
High sensitivity due to integrated low noise RF input amplifier
s
FM mixer for conversion of the US and Europe FM band (87.5 MHz to 108 MHz) and
Japanese FM band (76 MHz to 90 MHz) to IF
s
Preset tuning to receive Japanese TV audio up to 108 MHz, raster 100 kHz
s
Auto search tuning, 100 kHz grid
s
RF automatic gain control circuit
s
LC tuner oscillator operating with one low-cost chip inductor; no need for external
varicap
s
Fully integrated FM IF selectivity
s
Fully integrated FM demodulator; no external discriminator
s
Crystal oscillator at 32768 Hz, or external reference frequency at 32768 Hz
