Abstract
A divider is disclosed that presents an enhanced duty cycle for use with precision oscillators in clock sources. In one example, the invention includes a first divider chain to receive an input clock and produce a first divided output, a second divider chain to receive the input clock and produce a second divided output, and a combiner to combine the first and second divided output to produce a third divided output with a duty cycle greater than the first and second divided output.
Claims16
An apparatus comprising:
- a first divider chain to receive an input clock and produce a first divided output;
- a second divider chain to receive the input clock and produce a second divided output;
- a combiner to combine the first and second divided output to produce a third divided output with a duty cycle greater than the first and second divided output.
A method comprising:
- receiving a clock signal at a first frequency;
- producing a first divided output with a second divided frequency and with a first duty cycle;
- producing second divided output with the second divided frequency and the first duty cycle;
- and
- combining the first and second output to produce a third divided output with the second divided frequency and with a second duty cycle longer than the first duty cycle.
