I am trying to calibrate 512Hz RTC to 1ppm or <1ppm.
Desired Frequency = 512Hz
Average Frequency Obtained is = 512.0073Hz
What should be the value of CALP and CALM ???
(I used the CALP = 0 and CALM = 15, but still the ppm that I obtained is ~14)
Could you please help me with what should be take care of too obtain a value closer to 1ppm.
I used both oscilloscope and 53131a universal counter to measure the RTC calib frequency out.
