Since we're not trying to support HDMI post v1.4 we don't have signals above 10GHz on this interface at least. Thankfully none of the signal trace vias need to be drilled out since our signals always traverse the whole via. > *sigh* unfortunately symmetry is not completely achievable with the > drastically-reduced amount of space available. the HDMI signals come > out right at the bottom of the board. Hopefully most of what we can't accomplish with symmetry we can remedy with creativity. _______________________________________________ arm-netbook mailing list [email protected] http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to [email protected]
