    Hi Andrew,

    No special ripple requirements.
    CDCV304 can work in VDD range 2.3~3.6V, in this range, CDCV304 always can run.
    But power supply ripple frequency would be transferred to output spurs, and CDCV304 has no special PSRR design.
    So if customer like to achieve low jitter performance, ripple on VDD should be controlled, depends on clock jitter requirement.
