Abstract
A frequency divider for converting a standard frequency output from a crystal controlled oscillator to a lower frequency which is compatible with digital devices operating in a decimal mode. The oscillator output pulses and the complement thereof are fed to first and second AND gates which are respectively enabled by the complement and true outputs of a control flip-flop. The outputs from these two AND gates are ORed together and applied to the clock input of a synchronous, programmable, multi-bit counter whose carry output terminal is connected to a first D-type control flip-flop, through an inverter, the state of which determines the initial values to be periodically loaded into the multi-bit counter and which also controls the setting of the second D-type control flip-flop.
