Hell, Everything is in the title.
I'm working for very sensitive industry. I need to argue why in product I designed I have to introduce an x2 factor in the value of Rtc to get the good timing value.
For instance to get 25s with 270nF capacitor and 1024bit counter my resistor need to be 78K instead of 40k as the formula say. All my test on bench results in a doubled value of the resistor. When I plug my oscilloscope I need to set it to twice the frequency to get the correct timing.
Thanks in advance for your help.
