fractional-n pll clk generator
i need a clock whose frequency step is only 100khz or even less
i know in rf system there are fractional-n structure plls which can make the frequency step very small, but i never hear about fractional-n pll used as the clock generator.
can i use a fractional-n structure, eg ,sigma-delta as a clock generator, if needed?
or because of the low performance requirement, is there any other simpler structures to realize fraction-n function?
thx
