Hi Ryan,
Thanks for the update, but I would greatly appreciate if you can answer by following questions
1. What is the relationship between reference frequency and tracking rate. How did you arrive at 1/16th figure?
2.How do I measure and validate tracking rate and bandwidth claimed in the data sheet. Please explain the required test set up.
3. In the block diagram of typical SDC I find that VCO clock frequency changes with DC error. When the shaft angle is 180 degree sin(theta-phi) is almost zero. Then how does VCO work under this condition?
