Part Number: DP83867E


Hi

Our customer is considering heat radiation design for DP83867E.

Do you have some references, or user guide materials that we can share to customer.

e.g. 

How many via is recommended when it connect DAP-GND on the die to inner layer ground? How is via's size?

BestRegards

    Hi ,

    We do not have a reference guide on heat radiation design.
    However, we do have EVMs that have recommended layouts.
    I would suggest getting and EVM and experimenting with its thermal characteristics to what your customer will stress it to and based on that along with the design, make adjustments to the vias accordingly.

    Kind regards,
    Ross
