You may want to try the CPLD divider code I sent you many moons ago.  It'll
divide 5MHz down to 1PPS with no problem at all.  The output jitter ought to
be decent and easy to calculate.


I often use that code on a Reflock II board, because it has a nice HF input
conditioner in addition to power regs and JTAG connector.


Reflock II is not bad, but I am sure we could spin a board that work even
better for  general time-nut nuttiness(*) without a lot of difficulty.
Assuming of course there was sufficient interest .




(*)I would prefer Xilinx but I can live with Altera.
