A digital frequency multiplier provides non-integer frequency multiplication of an input signal. A multiplexer receives the input signal and an integer multiple of the input signal. A multiplexer control signal selects/toggles which signal the multiplexer will output and how long. A counter, clocked by one of the signals, provides the multiplexer control signal. The multiplexer outputs a pre-determined number of clock cycles of each signal to produce the desired non-integer frequency multiplied input signal. The present invention generates frequency multiplication without a phase locked loop (PLL). |
