# About Compliance Test and EMI data of W5500

## Question

Asked by KAWAZU on 2024-05-08 in Ethernet Chips.

Design Guide ''Wiznet Ethernet Design Guide_ENG.pdf'' includes Compliance Test and EMI data for W5100S.

Would you provide the Compliance Test and EMI report for W5500 ?

I would like to confirm whether W5500 can satisfy EMI Class B.

Please note that this board is made of W5500 and has passed all EMC tests.
