    Typically in order to build a filter at the o/p of a chip what data would you need?
    1) Spurious response or S-parameter data?
    2) What is the difference between the two data?

    A specification of spurious response attenuation would be a good start, but we would need more. I'm assuming a bandpass filter since spurs can be above or below the carrier. S-Parameters are used to characterize 2-port networks. I'm not sure they would be useful unless you said something about using a particular device.

    How about:
    1. Passband, upper and lower edge
    2. Transition bandwidth and attenuation
    3. Stopband attenuation
    4. Passband ripple
    5. Stopband ripple
    Then we can talk about active, passive, or digital.
