off Is the LVDS/TTCRx problem considered
a serious threat to our design? (2) will G-link
be available as dies by the time needed. Do we
have to reconsider connectors. (3) some chips
allow for wide clock range. Most require 8b/10b
encode by user (4) is the modularity acceptable?
Availability? Do we need any fall-back solution
at all ? If so, do we have to carry out tests ?
