Abstract: A system and method that measures the code non-linearity of a phase mixer (PMIX) during active operation of a clock and data recovery (CDR) circuitry. The PMIX circuitry generates a clock signal based on the PMIX codes. The PMIX circuitry receives a plurality of codes and based on the code value, adjusts the phase of the PMIX output clock signal. A number of times each of the plurality of PMIX codes occurs within a respective time period is determined. Non-linearity values are determined based on the number of times. The non-linearity values are stored in a memory.
