Abstract

A method an apparatus for synchronizing phases of one or more divider units comprise powering on a master divider unit to provide a reference signal. A phase of a slave divider unit is synchronized to the reference signal from the master divider unit by providing a power on pulse at the slave divider unit, synchronizing the phase of the slave divider unit to the reference signal using a digitally controlled oscillator, and powering on the slave divider unit after a first predetermined delay period following a rising edge of the power on pulse. By synchronizing a slave divider unit to the reference signal from the master divider unit, any number of slave divider units may be powered on and in-phase with each other.
