    is some voltage spike each 330 ms on AVDD can cause damages on CYUSB306X while the level noise is less than 20 mV?

      Hello,

      We have some voltage spikes each 330 ms on AVDD. If we do not considering those spikes, we have a ripple less than 20 mV, in according to the AVDD CYUSB306X datasheet specification.

      The question are, can we neglect those voltage spikes that appears each 330 ms while we have a ripple less than 20 mV?

      If we can neglect this, what impact can cause those voltage spikes?

      And can we replace the ferrite by a resistor for filtering those spikes correctly ?

       

      Thanks for your answer.
