Improvement of the characteristics of the frequency synthesizer in the quantum frequency standard on caesium-133 atoms
A new circuit of a frequency synthesizer is presented, which is an important functional node in the quantum frequency standard on cesium atoms. The advantages and disadvantages of the new signal synthesis method are considered in detail. By increasing the bit depth of the accumulating adder, it was possible to reduce the step of tuning the output frequency by several orders of magnitude. This method meets all the requirements for the
parameters of frequency synthesizers.
