  • Forum Post: DP83848C and Conducted Emissions Test

    Allison McKenzie Allison McKenzie
    We are using a DP83848C as a 10/100Mb ethernet Phy with an STM32 as the MAC and wurth 7499011121 magnetics. The circuit is laid out the same as the App Note, and the component values have been checked. The unit is failing Conducted Emissions testing in 100Mb/s mode. There is a constant load of chatter...

    Jean-Marie, Both of these components (Fox FXO-HC536R-50 50MHz oscillator, Bel SI-61001-F connector) should be suitable for use with the DP83848C. We generally recommend magnetics with +/-2% tolerance, but for many applications +/-3% is acceptable. As you progress with your implementation, please...

    Jean-Marie, The series termination resistors for CRS/CRS_DV and RX_ER are not required, but they can help you in the process of optimizing signal integrity. If you determine during prototyping that they are not needed, you can replace them with zero Ohm resistors or with traces in subsequent builds...

    Thanks you Patrick for these helpful informations. On the DP83848c eval board layout, mass plan and VCC plan are under RJ45 connector. I will follow recommendation write in all of your documentation and underline in your last answer, but why did there is those in this eval board ? I attach the beginning...
