I'm looking to divide a sine wave (easily converted to square) with a
divider down to a lower frequency. I'll probably start with about 100
MHz, and want to get it to about 3 MHz, requiring a division of
~100/3=33.3333 The exact division is unimportant, but it is essential
that it is not an integer. So somewhere between say 31.1 to 31.9, 32.1
to 32.9 or similar is needed.
The signal produced by the divider needs to clock an ADC. It is
*essential* that the rising and falling edges are equally spaced, so
the ADC get clocked regulary. Quite how often is not that critical,
but it must be regular.
Any suggestions how to go about this ???
