Hello,

 

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.

 

Best Regards,
Kou
