Why we test the peak-to peak value of ODCK is about 300mV?Since I think it is about 3.3V.

Is it wrong with it?

Thanks!

Hi Lian,

The amplitude of ODCK gets smaller as the frequency increases, but 300mV does seem pretty low. What frequency is it running at? Can you post a screenshot of the waveform, and share your schematic if you are able?
