Abstract:
A phase lock loop monitor circuit is disclosed. The phase lock loop monitor circuit may include a coarse tuning circuit operable to generate a coarse tune failure indicator, a frequency target lock detector circuit operable to generate a frequency target failure indicator, a cycle slip monitor circuit operable to generate a cycle slip lock failure indicator, and an abort logic circuit communicatively coupled to the coarse tuning circuit, the frequency target lock detector circuit, and the cycle slip monitor circuit, the abort logic circuit operable to generate a radio operation abort indicator based at least on the coarse tune failure indicator, the frequency target failure indicator, or the cycle slip lock failure indicator.
