Abstract
A frequency synthesizer circuit comprises a controller, a synthesizer and a voltage controlled oscillator are used to generate an oscillating signal in response to external commands. The synthesizer provides a lock detect signal to the controller when the synthesizer detects that the oscillating signal has reached a desired frequency following application of a load signal. A first timer, a second timer, and a counter are adapted to receive the load signal and the lock detect signal. The first timer provides a first measurement corresponding to an amount of time between the load signal and a first receipt of the lock detect signal. The second timer provides a second measurement corresponding to an amount of time between the load signal and a final receipt of the lock detect signal. The counter provides a count value corresponding to a total number of times that the lock detect signal is received inclusive of the first receipt and the final receipt of the lock detect signal. A memory device is coupled to each of the first timer, second timer, and counter, which has a data storage portion for storing the first measurement, second measurement and count value.
