So yeah, I'll stick with the ADI parts for now.

[context is SERDES inputs to FPGA]
Also, one has to count the number of 0-1 transitions in each word, such
that the event counter can be accumulated with the contribution from each
word.
That gets complicated. My straw man would be to get a single transition per
word working first.
