Abstract
Described are apparatus and methods for low power frequency clock generation and distribution. A device includes a low power generation and distribution circuit configured to generate and distribute a differential 1/N sampling frequency (F)(F/N) clock, wherein N is larger or equal to 2, and a differential frequency doubler configured to generate a single-ended multiplied frequency clock from the differential F/N frequency clock, and convert the single-ended multiplied frequency clock to a differential multiplied frequency clock for use by one or more data processing channels.
