I believe there's a mistake in the silk screening of the evaluation board, but I could be mistaken.
Data sheet: http://www.analog.com/static/imported-files/data_sheets/ADRF6516.PDF
My board appears to match the silkscreen in figure 60.
However this doesn't seem to match figure 58.
In figure 60: INP2 feeds into R44
whereas in fig 58: INP2 feeds into a junction to R46 and R32.
I believe that the silkscreen labels of INP2 and INM2_SE_P are switched, as well as OPP1 and OPM1_SE_P
