I have a simple question:
If the frequencie of the input and the LO are diferent, how will the output voltage be? Is the one port sent out a votage meant the difference and the other sent out the phase difference? or what?
Thanks

Hi Jingliang,
The Phase Frequency Detector is a special "mixer" designed for synthesizer applications and using it as you would normally use a mixer isn't recommended as there can be some hysteresis. You can use a mixer if you just need to compare 2 frequencies.
