Want to get the layout of the DM320007

Hi,
 
I'm looking for the layout of the DM320007.
 
Currently I'm fighting with a project to push SPI data to Ethernet.
With DM320007, everything looks fine. Same code with myself PCB (with only the same pic32 and the same Ethernet chip), I constantly read SPI data with wrong sequence.
At the beginning I thought may be the PKOB on the DM320007 helps to correct the data sequence. However I removed all unrelated chips from the DM320007, the DM320007 still works fine with the same code. So I'm worrying about my layout.

On Microchip's website of the DM320007, it only has the user manual with schematic. 
 
Could anyone tell me, where I can get the DM320007's PCB layout file? I appreciate your help.
 
Bests,
--- Kevin

    Problem solved. The wires on the DM320007 have Parasitic capacitance, but my PCB doesn't. 47pF capacitor added, and now problem solved.
    Thanks for your reading.
