Dear TI:

My customer use DP83TC811S-Q1, he parallel FB612,611,610,609 in TRDP and TRDN, the Bead FB609,610,611,612 is MPZ2012S102ATD25(P/N), does the bead will affect the data transfer?

DS of MPZ2012S102ATD25:

https://product.tdk.com/info/zh/catalog/datasheets/beads_automotive_power_mpz2012_zh.pdf

There is a low power mode app note of DP83TC811S-Q1, can you give me a link?

Thanks!

Hello Eric,

The 100Base-T1 standard does not call for the ferrite beads in that location. Since this is non-standard application, it has not been tested. Customer will have to perform their own system validation in this case.
