DESCRIPTION

The TDA7332 is an RDS filter, realized in switched capacitor technique.

The 4 biquad stage architecture is working with 4.332MHz clock.

Optionally a 8.664MHz xtal can be used.

The filter has a center frequency of 57KHz and a bandwidth of 3KHz. Input 2nd order antialiasing filter and output smoothing filter are provided.
