AD9467FMC Rev board differences

We are currently in the final stages of layout for our own variant of this board, the photographs for this board show distinctly different LVDS layout to the FMC connectors on each board.

 

RevB is shown on the Digilent site http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,648,1001&Prod=AD9467-FMC

 

What looks to be RevA on Analog devices site http://www.analog.com/en/press-release/01_31_12_ADI_FMC_Boards_Support_Xilinxs_FPGA/press.html

 

The LVDS routing on the RevA looks sensible for minimising timing mismatch across all the LVDS clock and data lines, but the RevB has completely unmatched track lengths, is there a good reason for this?

 

Would it be possible to please see the gerber files for the layout of the RevC production board?

 

Thanks in advance

 

Regards
