The TDA7000 is a monolithic integrated circuit designed for mono FM handheld radios with few peripheral components (small dimensions and low costs).
The IC has equipped with an FLL (Frequency-Locked-Loop) mechanism with a 70 kHz intermediate frequency. Active RC filters are used to attain the i.f. selectivity. The resonant circuit for the oscillator, which selects the reception frequency, is the only function that requires alignment. A mute circuit prevents erroneous reception while also filtering out excessively noisy input signals. To meet the radiation requirements, certain measures are necessary.
