Q
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?
A
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
