TDA7580

FM/AM digital IF sampling processor

Features

■ FM/AM IF sampling DSP

■ ON-CHIP analogue to digital converter for

10.7MHz IF signal conversion

■ FM channel equalization

■ FM adjacent channel suppression

■ Reception enhancement in multipath condition

■ Stereo decoder and weak signal processing

■ 2 Channel serial audio interface (SAI) with

sample rate converter

■ I2C and buffer SPI control interfaces

■ RDS filter, demodulator & decoder

■ Inter processor transport interface for antenna

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

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.
