... Low voltage single-chip FM stereo radio Rev. 01 — 2 August 2006 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 ...

... The RF AGC prevents overloading and limits the amount of intermodulation products created by strong adjacent channels. The RF AGC default and can be turned off via the I The TEA5761UK also has an in-band AGC to prevent overloading by the wanted channel. The in-band AGC is always turned on. 8.8 Local or long distance receive If bit LDX = 1, the LNA gain is reduced prevent distortion when a transmitter is very near ...

... This can also be done by setting bits Left Hard Mute (LHM) or Right Hard Mute (RHM) in byte TESTBITS, which allows either one or both channels to be muted and forces the TEA5761UK to Mono mode. When the TEA5761UK is in Standby mode the audio outputs are hard muted. ...
