I am designing a prescaler to provide divide ratio from 2 to 255 for 4GHz
vco
clock. Basically that is just a cascade of 7 cml_divide_by_2/3_cell.
Does anyone know what test cases should I run to verify the prescaler design
in detail? Like which divide ratio(s) can stress the circuit most? How to
check if prescaler works under dithering scenario?
Thanks and happy holiday
