Envelope Bandwidth of AD8302

Hello everybody,


I have a quation regarding the envelope bandwidth of AD8302 phase detector.
In the datasheet the envelope bandwidth is defined by 30 MHz if no external capacitor C_FLT is used, but only the internal capacitor of 1,5 pF.

My quation is, how the bandwidth of 30 MHz is calculated?

On the other side the integration time constant is: T = (Rf x C_AVE)/K. Is it known which values the K and Rf have?


Best regards
