DESCRIPTIONThe 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 fil-
ter and output smoothing filter are provided.

Note (1):The phase non linearity is defined as: ΔPh = | -2 φf2 + φf1 + φf3 |
where φfx is the input-output phase difference at the frequency fx (x = 1,2,3)
Note (2): The 3th harmonic (57KHz) at the output (pin12) must be less than -40dB in respect to the input signal plus gain.
