Hi Expers:

Could used other CMC to replace DLW32MH101XT2L?

What should I need noting，and what terms do I need to test for proving the new CMC can comfit DP83TG720？

For example，EMC， SI？

Hi Zhang,

DLW32MH101XT2 is the recommended CMC for the DP83TG720 and the one which has been used for validation of this part to datasheet specs. Which CMC are you suggesting to use instead?

Thanks,

David

Hi David:

We want ro use AMCW3225L-2-101TR01 to instead. But we donot kown what terms I need to test for proving the new CMC is comfit for DP83TG720

Hi Zhang,

Functionality cannot be guaranteed using a CMC outside the datasheet requirements, I would suggest to use the DLW32MH101XT2. Signal integrity and EMC performance may be effected by changing this component.

Nonetheless, compliance testing can be performed to validate the transmitter performance.

Thanks,

David

Hi David：

In other word，if the new CMC can comfit Signal integrity and EMC performance，is that can use it to replace the one which recommend in datasheet？

Hi Zhang,

If signal integrity and EMC are unaffected by this part and it passes compliance, you may use it.

Best regards,

Melissa
