Hi,

You have to be more clear on your doubt. If it is very low frequency signal at the output of VCO then jitter is not much.

If you need more details, don't hesitate to contact me.

Jitter will remain the same.

Think of divide by 2 as eliminating alternate edges. The remaining edges will have same jitter as from original source, unless the divider is adding more jitter.
