Are you having trouble with the mathematical modeling part, or the XCos part? The biggest issue that I find in modeling phase-locked loops is first in deciding what sort of model I want (i.e., do you want a full-on continuous-time circuit model, a fully linearized model of the loop in lock, or something in between), and then, if I'm modeling something more abstract (e.g. a fully linearized model), how I want to represent everything (this is particularly challenging if the fully linearized model is in sampled time, and uses something non-traditional for the phase detect, "NCO", or both). -- Tim Wescott www.wescottdesign.com Control & Communications systems, circuit & software design.
