ABSTRACT:
A phase locked loop (PLL) oscillating circuit includes a first oscillating circuit, a lock detector and a reference oscillating circuit. The first oscillating circuit generates an oscillation signal with a first frequency, and controls the first frequency based on a reference signal. The lock detector detects phase lock between the oscillation signal and the reference signal to a lock detection signal. The reference oscillating circuit includes a crystal oscillation element, and generates the reference signal. An oscillation state of the reference oscillating circuit is controlled based on the lock detection signal.
