Frequency Calculation and Register Definitions

The CY22150 is an extremely flexible clock generator with four basic variables that are used to determine the final output frequency. They are the input reference frequency (REF), the internally calculated P and Q dividers, and the post divider, which can be a fixed or calculated value.
