I am trying to track an incoming carrier signal around 150MHz for an indoor application. The carrier frequency is one of 50 random channels with a frequency hopping pattern. Most of reference designs with PFD and PLL are for clock generations with a preset frequency. Can I use the incoming signal in place of a normal reference XO source? There are reflections and possible other impairments to the incoming signal. I am thinking to use a comparator such as ADCMP553 to cleanup the signal in front of the PFD. Are there any potential issues I should be aware of? Thanks.
