Hello,
Have anyone had any luck designing a phase lock loop with very small bandwidths, e.g. less than 0.2 Hz. I need to lock a 100 MHz Ultra low oscillator to a 10 MHz ultra low oscillator and I need a loop bandwidth less than 0.2 Hz. Quartzlock do a digital PLL board with bandwidths to 1 mHz. However I never got it to work. The 10 MHz reference has phase noise of -116 dBc/Hz at 1Hz offset. The 100 MHz VCO make -104 at 1 Hz. Obviously I'm trying to preserve the 100 MHz phase noise. Any advice would be appreciated.
