What's a clever, simple, reliable (pick 2 of 3) way to get 16 MHz out of 10
MHz? Low phase noise isn't a big requirement and jitter doesn't need to be
sub-nanosecond. The main requirement is perfect cycle count accuracy. This is
for driving a 16 MHz microcontroller from a 10 MHz Rb/Cs/GPSDO. 10 MHz input
is likely sine; 16 MHz output is 3v3 or 5v CMOS.
There should be a PLL chip that includes the M and N dividers, but I'm not
familiar with that area.
Use this for f * 16:

and a 74LVC for / 10.
The NB3N3020 could do *1.6 directly, but only for input frequency > 25 MHz.
