BQ79600-Q1: Use oftransformer with integrated common mode choke

Part Number: BQ79600-Q1

Tool/software:

Dear TI-team,

I would like to implement SPI communication via a WE transformer with integrated common mode choke. Here is an example circuit diagram:

Is there anything to say against it?

    Hi Rene,

    The choice of transformer primarily affects you EMI results. The primary characteristics that are important for choosing a transformer for our product are:
    -The common mode rejection ratio
    -The insertion loss,

    -the primary inductance.
    -Return loss

    You can compare the datasheet transformers with the WE transformer to determine any EMI benefits 

    Best regards,

    Abdel
