Hi,
We have failed the Immunity test in the PCB which has this Hub IC in it.
During the Immunity test, IEC-61000-4-3 Electric field test 10V/m USB Hub IC CY7C65632-48AXC is resetting at frequencies around 370 MHz.
We would like to know if this IC is certified for the Immunity test IEC-61000-4-3 Electric field test 10V/m or is there something missing in my schematic?
I would also share the schematic if needed. Hoping for your quick response. Thank you.
Solved! Go to Solution.

Hi,
We have carried out the immunity tests for our HX2VL DVKs, including the IEC-61000-4-3 test and passed the same so our hub should be compliant.
Please check section 4.4 of the App Note for hardware guidelines to consider for EMI- https://www.cypress.com/file/122726/download

Hi Sanaya,
Thank you for your answer. I had followed the guideline which you shared while designing the Hub. But I am still facing the issue.
Can you verify my schematic/layout to find the issue?

Hi,
Yes, please share the schematic and layout files for us to review. If it is confidential, you could send them using the private message option or send a mail to sanm@cypress.com as well.
