AD9545 Power supply

Hi,

In the AD9545 Evaluation board schematic, all the VDD power supply pins are isolated using 0E. Attached is the evaluation board schematic.Please let us know is there any specific reason to isolate individual VDD pins or all of them can be shorted together?

Regards,

Sudarshan
