1.Can i set pin 13 30 31 48 Vd(analog suooly(3v))=3.3V?
2.Does the pin 1 12 16 27 29 32 34 45 GND have analog GND or digital GND?
1. Yes, the AD9218 can operate with a stable Vd supply ranging between 2.7V to 3.6V (3.0V nominal) as noted in the Power Supply specifications Table 1 on datasheet page 3.
2. We do not differentiate between Analog and/or Digital Ground on the AD9218. The datasheet provides a good example of our legacy Eval Brd layout that used a common low impedance GND plane to achieve the AD9218 performance plots shown in the datasheet.
