Good morning! We discuss with Kevin G. precise phase control (0 to 180 deg. with step of 1 deg) of sinewave 1 to 1000 MHz few days ago. We are able to use PLL along with DDS to reach 1 GHz output - even if the cost may grow. The question is - can PLL work with sinewave input signal? The phase of output is exactly the same as the phase of input? Or PLL is nor the right decision for this task?
