Abstract
An improved crystal oscillator and output circuit is disclosed. The oscillator has a normal operating mode and a low-power mode. In the low-power mode, a reduced current which is sufficient to maintain oscillation is supplied to the oscillator and the output circuit is disabled. The oscillator can subsequently be returned to normal mode and the output circuit enabled. Since the oscillator is never shut completely off, the time required to resume normal mode oscillations is reduced.
