Abstract
A frequency synthesizer for generating a low noise and low jitter timebase of a reference signal generates first and second output signals a difference frequency that is low enough for use in sub-scanning is implemented with a first incrementer, having a preset increment and a preset end value Econtrolling a first fractional divider and a second incrementer having a preset increment and a present end value Econtrolling a second fractional divider, wherein each of the incrementers is clocked from the output signal of each fractional divider so that, when the end value E, Eis reached, an end signal is output and the incrementers are reset to a carryover value as a new starting value and the end signal is switched between the division factors of the fractional dividers so that the switching sequence of the end signal is periodic with the output signals of the fractional dividers.
