and tuner diversity

■ Front-end AGC feedback

Description

The TDA7580 is an integrated circuit

implementing an advanced mixed analogue and

digital solution, to perform the signal processing

LQFP64

of an AM/FM channel. The HW & SW architecture

has been devised to perform a digital equalization

of the FM/AM channel, and a real rejection of

adjacent channels and any other signals,

interfering with the listening of the desired station.

In severe multiple path conditions, the reception is

improved to get high quality audio.
