I have my custom clock on the system that I want to apply the frequency adjustment on. IN the function adjFreq(double adj) what does "adj" really mean? Basically, I want to apply the correction on my custom clock by using this interface shiftCurrentFrequency(long int shiftInHz).
What I am doing now as the following:
__s64 freqShiftInHz = (long long int) (currentFreq * adj) / kPpb;
shiftCurrentFrequency (freqShiftInHz);
Thank you
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
More info:
I will be using this custom clcok to steer multiple ethernet cards. As all of them are drivin by this clock.
Custom clock max supported ppm = 1000
Custom clock center frequency = 100MHz

adjshould be in ppb, so it should be justwhere 10 = 1e9/100MHz. It can be also -10. I don't know the direction of adjFreq and your function.
If your parameter is jsut an adjustment in Hz and not the resulting frequency, this should work.
