Abstract
An oscillator circuit includes a frequency setting circuit, a first and a second clock signal generating circuit, a clock synchronization circuit, a control circuit, and an output circuit. The first and second clock signal generating circuits generate first and second clock signals respectively. The control circuit outputs a frequency setting signal via a second node, outputs the first clock signal via a sixth node, and outputs the second clock signal via a seventh node when the first frequency selecting signal is at an effective voltage level; otherwise, outputs a second synchronization control signal via the second node, outputs an external synchronization clock signal via the sixth node, and outputs a first clock signal via the seventh node. The clock synchronization circuit generates the first and second synchronization control signals. The output circuit outputs the first or second clock signal.
