I think I may need to change the LPF feeding the EFC in my GPSDO to get rid of dithering jitter. Is there any point in adding a resistor and cap in the EFC line, or do I need to go back and change the values in the op-amp circuit feeding it? Currently an op-amp directly feeds the EFC pin. I guess this boils down to something like: is there any meaningful current flow in EFC circuit in this oscillator? Or should I add them but will I probably have to change the existing filter, as well?
