I'm thinking of making an 8MHz about-square clock starting from a 24MHz about-square clock. All signals are CMOS with 3.3V(±10%) power.
What are my options? I'd like it low-power, cheap and easy to source, compact.
Note: the divide-by-N 74HC4059 does not match my "8 MHz about-square clock" requirement; the output duty cycle is about 1/3.
Update: I located that On Semi application note trying to do what I want, except that's using a lot of circuitry more ICs than in my dreams. I wish that divide-by-3 function existed pre-integrated...
Update following comment about the lack of symmetry requirement: the available 24MHz at input has tlo>16.5ns, thi>16.5ns, and negligible jitter. The output signal should have tlo>50ns, thi>50ns, and no long-term drift. Thus if my math is right, in the above circuit I have to keep the difference of delay between (rising-input-edge to rising-output-edge) and (falling-input-edge to falling-output-edge) within ±8ns (with 166ps engineering margin).
