Abstract
A programmable frequency divider for dividing the frequency of a supplied high-frequency signal directly into a lower frequency includes a plurality of 2-scale-factor prescalers or programmable frequency divider units each capable of being switched between divide-by-2 and divide-by-3 modes. The 2-scale-factor prescalers are connected in cascade for producing an output signal which is frequency-divided at one of multiple division ratios at a time.
