Abstract
A mobile communication device includes an analog clock and a digital clock circuit. The analog clock circuit is configured to generate an oscillating output. The digital clock circuit is configured to generate a digital clock output having a frequency that is substantially equal to the frequency of the oscillating output.
Claims20
An electronic device comprising:
- a first clock circuit configured to generate a first clock output at a first frequency;
- a second clock circuit configured to generate a second clock output at a second frequency that is substantially equal to the first frequency;
- and
- a controller configured to selectively enable only one of the clock outputs at a time to provide a clock signal.
