    Hi user5977407,

    Please refer to the datasheet, Pin Configuration and Functions section. The Description of CPL, CPH, and VCP states the capacitors to use.

    The charge pump was designed to use the capacitors listed in the datasheet. For CPL/CPH, a 100nF capacitor is recommended. For VCP/VM, a 1uF is recommended.

    There is some capacitance variation allowed. Typically the capacitors can vary up to 30%.

    Please use the recommended capacitors.
