I am Satyabrata. We are using AD9265 evaluation board. We gave analog input of 1V pk-pk, clock input of 100 MHz frequency and 1.8 V pk-pk sine wave.
We checked the pins of databus of the evaluation board.
Results what we have got are as follows
1. common mode voltage - 0.899 V
2. Vref - 0.996 V
3. DCO - 100 MHz frequency same as the input supply clock frequency, 1.8 V pk-pk value
4. D0 - voltage 1.813 V
I am attaching here the waveform we got on the oscilloscope. Please have a look at those.
Attachment(1) - waveform of DCO(channel 1) and D0(LSB)in channel 2
Attachment(2) - waveform of D15(MSB)
Now, please reply me whether these are the correct result or not.
