I am planning on using  the AD9716 with the following power supply voltages:

AVDD=3.3V,
DVDD=1.8V,
DVDDIO=1.8V,
CVDD=1.8V

Can you please provide the digital specification for this power supply
combination?

 

Here are the required input specifications:

For 1.8V supplies DVDDIO = 1.8V and CVDD = 1.8V
ViL   0.5v max
ViH  1.2v min

For both data and the DCLKIO and CLKIN
1.8V Q Channel or DCLKIO Falling Edge
Setup time: 0.25ns
Hold time:  1.2ns

1.8 V I Channel or DCLKIO Rising Edge
Setup time: 0.13ns
Hold time:  1.1ns
