Based on analog input voltage of 1-dB FS referenced to a 1.3 Vpp full-scale input range and using the external voltage references at
fCLK = 35 MSPS with AVDD = DVDD = 3.3 V and DRVDD = 3 V at 25°C.
NOTE 4: The analog input bandwidth is defined as the maximum frequency of a 1-dB FS input sine that can be applied to the device for which
an extra 3-dB attenuation is observed in the reconstructed output signal.
