I have a question regarding timing of Piccolo F2807x. I want to use it to measure the frequency of a an 85 Mhz sine wave signal. I am planning to use ecap module. Mz idea is to capture two rising edge of this signal and then store the value of the TSCTR to calculate from this the frequency just like in example 3 in
From my understanding there is no need to divide the signal as long we have a system clock that is running at least with the frequency of the signal or more but there is also the option to use a prescaler and work with lower frequency system clock is that right? or is that ecap can not catch such a high frequency signal?
Thanks.
