Abstract
A crystal oscillator clock circuit which facilitates switching its output between an internally generated clock signal and an externally generated clock signal. A feedback loop detects the presence of an externally generated clock signal applied to an output pin of a crystal oscillator circuit and powers down the internally generated clock signal. As a result, the crystal oscillator clock circuit simply passes the externally generated clock signal as its output signal.
