Hoping some intelligent soul out there might be able to
help me solve a perplexing problem. Here goes:

I want to put together a frequency synthesizer (square wave)
that can adjust between 1 and 10 MHz with 255 steps (ie. 35k Hz
per step).

The PLL's I've looked at don't have the range, synthesizers
don't have the speed (500k Hz max.)

I need the 10 MHz top end but can live with less bottom range.

Ideas???

Appreciate any constructive thoughts on this.

Thanks.
