This is a reference design, distributed in our favourite format, self extracting exe file.

ftp://ftp.altera.com/outgoing/devkit/12.1/cycloneIVGX_4cgx150_fpga_v12.1.0.exe

In there is a *.pdf file showing the multi-port caps.  Altera seems to have a thing for them.

So does Freescale.  It seems to be a happening thing.

Yes, they are more expensive.  There are multiple suppliers, I assume this means multiple
patent licensees.  The BOM reduction comes about from needing less of them from what I can
see.
