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.
