I have a question about AD9220 A/D converter.
Pls refer to P.3 DIGITAL SPECIFICATION.
When AVDD=5V and DVDD=5V,Vih of CLOCK INPUT is 3.5V(min).
If AVDD=5V and DVDD=3.3V,I understand that Vih is 3.5V(min) .
Because the CLOCK INPUT is considered a part of analog circuit.
Is it correct?.
It would be greatly appreciated if advice could be gotten.
