    Regarding voltage noise tolerance of CYUSB3314.

    YuMa_1534086

      Hello Cypress.

       

      Could you please let us know noise tolerance of CYUSB3314?

       

      Below capture is noise tolerance of CYUSB3314 at DS(Table 8. DC Electrical Characteristics).

      But DS does not describe noise ripple frequency.

       

       

      Our customer would like to know noise tolerance of CYUSB3314 under below conditions(1 to 4).

      Could you please let us know noise tolerance value under both 1.2V and 3.3V conditions.

       

      1. Max p-p noise level permitted when noise ripple frequency is “0.1MHz”.
      2. Max p-p noise level permitted when noise ripple frequency is “0.2MHz”.
      3. Max p-p noise level permitted when noise ripple frequency is “0.3MHz”.
      4. Max p-p noise level permitted when noise ripple frequency is “Above 1.0MHz”.

       

      And does voltage noise tolerance level described in DS change by noise ripple frequency?

       

       

       

       

      Best Regards.
