[Arm-netbook] HDMI High-Frequency Layout: Recommendations--Taper

[Richard Wilbur]

Thanks again for the pictures and the video.

Concerning the keepouts under the connector:
1.  At the north boundary I would pull the edge up a little further north away from the northwestern differential pair.

2.  At the west boundary I see your point regarding layers 4 and 5.  Looks like you have made a good solution.  I suppose you could add 5mil additional overlap.  How much overlap does it currently have?  How much opening from the edge of the keepout on layer 4 to the edge of the closest connector pads?

I would vote to keep the layer 5 holes under the layer 6 ESD pads for the same reason we added them to layer 2 for the ESD pads on layer 1.

Some of the adjustments on layer 6 might be taken care of by modifying the net groups to create an "HDMI High-Frequency" group which contains only the differential pairs {HTX2P, HTX2N, HTX1P, HTX1N, HTX0P, HTX0N, HTXCP, HTXCN}, apply the 15mil conditional clearance rule to that group.  Then see what issues remain.
