I have a question about layout of evaluation board of ADV7181D.
Please refer attached file "ADV7181D_Evaluation_Board_Rev0_Layout.pdf"
My customer is going to draw layout of their board.
So they refer the evaluation board layout.
About the layout of Exposed Pad, we think it is connected to GND with Four-layer Through-Hole VIA of your evaluation board.
But on the layer 1 (page 2 of "ADV7181D_Evaluation_Board_Rev0_Layout.pdf"), we can not see round mark (circle) which shows VIA.
(We can see round mark (circle) which shows VIA on layer 2, 3 and 4 at Exposed Pad.)
Why is there no round mark (circle) which shows VIA on the layer 1?
