HSMC Version 1.2

Hello,

I am trying to connect CX4 cables to the Arria II GX FPGA board and what I require is a HSMC-to-CX4 adapter which can be found from MorethanIP, Altera's provider. However, the description of the adapter requires HSMC version 1.2 and I cannot find HSMC Specification v1.2 anywhere in the Altera website and I can only find version 1.7.

I am wondering if the pin assignment of the HSMC spec is the same for v1.2 and v1.7? Also, would the HSMC-to-CX4 adapter work on the Arria II GX FPGA board.

Thanks
