Grounding confusion for ADC and DAC on Same Board

Other Parts Discussed in Thread: ADS5474, DAC5675A

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
