Arria II Gx To DDR3 SSTL-15 Class I Interface

Hi,

I would like to connect to Arria II Gx a DDR3 device via SSTL-15 class 1 interface.

I've opened up the spec of Arria II Gx (see attached) and I didn't see OCT for the receiver in Gx version.

So then how do I terminate IOs of Arrial II Gx for SSTL-15 which act as receivers or bidirectional IOs ?
