Hi All,

I am facing a big challenge and before I will go ahead I would like to
ask anybody who has a good idea.
The solution not need to be cost effective.
I need to generate square wave with close to 50% duty cycle,
but quartz precision.
The frequencies are :   400Hz      -   4KHz   10Hz steps
                                        4KHz       --   40KHz  100Hz steps
                                        40KHz     --   400KHz 1000Hz steps
                        400KHz     --   4MHz 10000Hz steps

I really appreciate any idea.

Thank You,

Peter     ( schupet@dvp.com )
