Hi,
I am using ADC (ADS5474) - DAC (DAC5675a) Data conversion Board with 400 MSPS High speed Design.
I have separated Power AVDD and DVDD for both ADC and DAC.
As per EVM of both, it shows GND is common in individual EVM board.
But while working both (ADC-DAC) in same board, Do I need to keep Common GND or Do I need to Separate it as GND-ADC and GND-DAC?
Thanks,
Mrudang
