DS90UH926Q-Q1: Noise of power supply

Part Number: DS90UH926Q-Q1

Hi,


Let me confirm about meaning of following spec.

Is above "noise frequency" included "ripple noise" of Vddio and Vdd33 ?

(Ex, if ripple noise is 40kHz and Vp-p is 80mV, there is no issue because Vp-p of noise is less than 100mV and also frequency of noise is less than 50MHz.)

Best Regards,

  • Ripple noise has a frequency component and was applied to Vddio and Vdd33.
    Correct, yes, if the ripple noise is 40kHz and Vp-p is 80mV, there is no issue because Vp-p of noise is less than 100mV and also frequency of noise is less than 50MHz.
