DP83869HM: DP83869EVM board does not match User Guide

Other Parts Discussed in Thread: DP83869EVM

I just got a DP83869EVM board from Mouser and it does not match the details in the User Guide.

The User Guide I have (which I got from the website a week ago) is SNLU237–September 2018

The labels on pin headers do not match the labels on the board, for example the pin header labeled OP_MO [0] is in a different location on the board than in the picture in User Guide. Resistor names in the schematics are in completely different circuits on the board.

These discrepancies are bothering me. I'm relying on the User Guide to help me set the board up right, if it doesn't agree with the actual board I'm worrying I might spend weeks trouble shooting something that really isn't a problem.

So the main question is " is there a version of the User Guide that actually matches the board?"

Thanks,

Hi John,

Sorry for the inconvenience. Let me check internally and get back.

I did some tracing on the board and it looks like the labels on the board are correct, so I'm going ahead using the board.

The other problem is that the SMA jacks for the SGMII interface are not soldered on the board. The pictures all show these jacks on the board, and neither the description nor the User Guide mention that the user will have to buy some jacks and solder them on the board. I'm wasting some more time while I order the jacks.

The User Guide DID mention that I would need some .1uf caps to add, but doesn't say what size, I assumed they would be 0402 so I had plenty of those on hand. It did turn out to be 0402, but it would be nice if the User Guide mentioned the size.

Thanks,

John S.

Hi John,

So the labels on the board are correct but the User's guide is missing information about what parts need to be ordered. We will update the User's Guide with the missing information and also update the picture.

Thanks for looking into this.

I DO have the EVM working well now.
