Hi I agree that improving the basic accuracy is a bit of a stretch. The first thing to look for would be temperature sensitivity that you could take out with a correction table. In another post you beat me to the 200 MHz chain and it’s phase locking. One might be able to do something interesting with a digital filter on the PLL ...
