2 DESCRIPTION
The TDA7332 is an RDS filter, realized in switched
capacitor technique.
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 fil-
ter and output smoothing filter are provided.
The 4 biquad stage architecture is working with
4.332MHz clock.

Note (1):
The phase non linearity is defined as: DPh = | -2 ff2 + ff1 + ff3 |
where ffx is the input-output phase difference at the frequency fx (x = 1,2,3)
