Other Parts Discussed in Thread: LMR14030
Hi,
My customer is having a project of Building Automation DDC that is using our DP83848I, their first version PCB has some EMI problem, so I give them some information and documents from ti.com for them redesign the PCB. In the attachment is the 2nd version Ethernet and related power stage part layout.
Because of the cycle time restriction they don’t have to much time for this project, hence they would like us help to review the layout and see if there is potential EMI problem in this version.
Could you kindly check the layout in the attachment and give some feedback to our customer? The layout of Ethernet IC and related power supply is as following.
Thanks a lot for your support!
