Reference Manual

For QDRII devices, the interface supports 10.8 Gbps of throughput at 300 MHz
(600 Mbps × 18 pins). The QDRII bandwidth doubles to 21.6 Gbps when considering
combined read and write bandwidth. For QDRII+ devices, the interface supports
12.6 Gbps of throughput at 350 MHz (700 Mbps × 18 pins). The QDRII+ bandwidth
doubles to 25.2 Gbps when considering combined read and write bandwidth.

Table 2–50

lists the QDRII interface pins.
