I would like to start to layout design .
Could I have information about layout of ADM3053?
I checked UG-234
1) 1) Edge Guarding
UG-234 layout doesn’t have the edge guarding on VISO side.
a) Doesn’t it need ? It isn’t so effective?
b) Could I see the noise data of this evaluation board, like AN-1109 figure 5?
2) 2) ADM3053 Board construction
ADM3053 evaluation board is 6 layers
a) a) Could I know t he Thickness of each layers? (special controlled?)
b) b) Usage of Layer 5?
3) 3) Safety capacitor and Stitching capacitance
We doesn’t have a space for stitching capacitance
And we try to use safety capacitor..
The document says, a safety capacitor effects under 200MHz.
ADM3053 internal clock frequency is 180MHz.
a) How effective is Safety capacitor ?
b) Could I have your advice about such small area layout
Thank you for your help
