AD9218BSTZ-65 Power supplies

Hi,

Two quick questions:

 

1. The DS suggests that both analog and digital typical voltage is 3.0V. I'm using the standard 3.3V. Should I use a seperate 3.0 power supply for the analog supply? Is it at all critical?

 

2. Should I seperate the ground planes of the ADC with ferrite? Or just connect it directly to the digital ground plane to reduce return currents?

 

Best regards,

Assaf.
