Hi
Im trying to use a ds1075-100 (programable oscillator divider) wich the spec
says works down to 29.3khz. (upto 100mhz)
I programed it to give an output of 32.768 khz (from 4.096 mhz) wich is just
above that however it gives no output. if i program it to give frequencies a
bit above that it works fine, the confusing thing is it wil hapily give
lower (or higher) than 32.768 khz ie 20khz or even 7khz, but just not the
frequency i want, the frequency ratios confirm i have programed the corect
divider value, and the mux register.
this is a bit frustrating and rather confusing how or why would they design
a chip wich cant work at 32.768 khz but at most other frequencies ???
