Dear Sir Madam
For a client of mine I need to develop a very low cost high frequency phase comparator:
My idea is to use a low cost PLL synthesizer IC as a phase comparator by applying 2 high frequency (2GHz) signals divided down to 20 MHz using the R and N dividers inside the IC ,And the 2nd signal will be divide using an external prescaler down to 500 MHz and down to 20 MHz using the internal reference input divider inside the IC , both signal who divided down to 20 MHz will be applied to the phase detector and phase detector output lowpassd and rectify to DC level voltage - the level of the DC voltage will be correlated to the phase shift between the measured signals
My question : Would this idea work?
