Frequency synthesizer
A frequency synthesizer comprising a reference oscillator configured to generate a first clock signal with a reference frequency and a divider controller configured to receive the first clock signal, a second clock signal, and a multiplier value. The divider controller is configured to obtain a ratio of a frequency of the first clock signal to a frequency of the second clock signal and divide the resulting ratio by the multiplier value to obtain controller output value. A divider is configured to receive the first clock signal and controller output value and output an output clock signal with a frequency equal to the frequency of the first clock signal divided by the controller output value.
