Are those values with the same predivider (n) value ? I suspect the ability of the DCO to lock might depends on its input rate and an m range So if n change, it might possible that the m range will be different. ... at least, that's my guess :) > > (I'm providing this info because it may help finding a decision > whether ranges are good or not.
