GENERAL DESCRIPTION
The TDA7000 is a monolithic integrated circuit for mono FM portable radios, where a minimum on peripheral components
is important (small dimensions and low costs).
The IC has an FLL (Frequency-Locked-Loop) system with an intermediate frequency of 70 kHz. The i.f. selectivity is
obtained by active RC filters. The only function which needs alignment is the resonant circuit for the oscillator, thus
selecting the reception frequency. Spurious reception is avoided by means of a mute circuit, which also eliminates too
noisy input signals. Special precautions are taken to meet the radiation requirements.
The TDA7000 includes the following functions:
