I have a 100mVp-p signal and the frequency range is between 100KHz to 10MHz.
the AD9248 has some Reference configuration to select Vref (it could be 0.5V or 1V).
*if I want to sample the signal with AD9248, which voltage reference is better to get best resolution?
*I have attached a pic in the below that shows the interface circuit. How can I calculate the input resistance and capacitance of the interface? (please help me in details,in calculating and what's the role of VINCT_A? )
