For some reason I'm having troubles finding a programmable clock divider chip. I have a 20MHz reference clock that I need divided by 23. I would like the option of changing this divide ratio if needed. I can't seem to find a simple single chip solution (smaller the better). I'm currently looking at CPLDs which is not a clean solution because of ICP. The 40103 is another option but is border line with the max speed vs my operating voltage. I'm also looking at using the R or N counters of a synthesizer chip if this is at all possible.
Seems to me there should be a two wire programmable SC70 divide-by-N available, but I can't seem to find anything close.
Any thoughts?
