Hi, I want to use an external clock on my limesdr mini. After research I have two questions left:
The LMK00105 states a maximal CLK-IN voltage of 2 Vpp. My ocxo has an 10MHz square wave output which swings between 0V and 3.3V. That said I should be able to connect my ocxo directly to the limesdr without attenuation. Is this correct?
After changing to an external reference clock the LimeSDR Mini doesn’t pass a certain calibration. Is the calibration in question the one of the VCTCXO ADC? So this doesn’t affect the tx or rx calibration in any way ? (I am asking because I learned that the limesdr transmits a constant carrier if the tx calibration fails which I want to avoid)
