Frequency divider ICs for RF
A divider integrated circuit for RF (say ÷10) works outputting a 'stretched' single sinewave of 10 cycles duration period; or will output one equally 'short' as-input-cycle every 10 inputted ?
Prescalers ICs are analog for sinewave RF or work square wave in and out ?
Is there a fixed ÷1000 prescaler IC in the market ; fin max = 200MHz?
CMOS prescalers I have seen, work -better- with square waves
(in terms of things like phase noise) but are made to work well
enough with sine wave input.
I think 200MHz is kinda low to interest the "RF" semiconductor
folks and I haven't seen single chip prescalers with /N greater
8. This is somewhat due to difficulties running complex counters
at >GHz in pennies-per-part technologies.
You might look at PLLs with pin-strap /N, and see if that
counter's output is pinned out in any way.
Output of a Prescaler is square wave due to its nature..
There were prescalers in the market form Siemens, Plessey,Motorola,Telefunken 20+ years ago but it's possible to find them again in ebay or similar second hand markets.
They have been working up to 3 GHz and division ratios were 16,32,34,128 etc.If you find one them, you can use HiSpeed CMOS prescalers beyond the first one.
On Semiconductor manufactures still such prescalers.
