PCB Layout Guidlines for Ethernet?

Hi,

Any PCB layout guidlines exist for the LM3S6965, specifically the connections and layout for connecting the PHY to the magnetics?

In fact any PCB related hardware documentation at all? Lots of good documents from the software point of view here but not an awful lot "obviously" available for hardware design... schematic symbols, chip footprints etc...

Thanks,

Liam Redmond.

Re:PCB Layout Guidlines for Ethernet?

I'm looking for PCB guidelines as well, such as Board type, recommended trace width, etc...

I'd like to third the request. I'm looking for any reference designs for the 3s811, but I'd take general schematic suggestions or layout suggestions.

I'd like to add my voice to this. EVB schematics are nice, but don't offer the necessary detail.

We have an application note planned for board layout recommendations. When it is ready, I will post a message indicating it can be downloaded.

Re:PCB Layout Guidlines for Ethernet?

We also need some more information regarding the selection of the ethernet magnetics. There are a lot of choices out there and virtually no guidance with respect to the particular needs of the Luminary PHY.

Put another way... Can anyone tell me what factors were used in the selection of the part used on the LM36965 Evalutation Board? It uses a Pulse J3011G21DNL - See http://www.pulseeng.com/products/datasheets/J409.pdf

Here is one source of info. See the curious comments on slide 46 of http://www.scvemc.org/files/Ethernet_Magnetics_EMI.pdf
(his diagram seems reversed, however)

Is there a better choice of information out there?
