I want to use the ADRF6601 with a 10 MHz reference input freq. I see the Spec claims a lower limit of 12 MHz. Is this due to a concern about the rise/fall times of the reference clock ?
If so, would a square wave 10 MHz reference input be good ?
Or, do I need to use the internal reference doubler to produce 20 MHz and then divide ?
When I read the Spec, I do not find a parameter for the maximum phase comparator frequency. I woule like to use 10MHz into the phase comparator, preferebly with a reference divide ratio of 1.
What is the maximum allowable reference frequency into the phase comparator ?
