Table 2–36 lists the DDR3 interfaces component reference and manufacturing
information.
QDR II Interface
The QDR II interface consists of two 72-Mbit QDR II burst-of-two SRAM devices.
Port A has a 18-bit read data bus and a 18-bit write data bus while Port B has 36-bit
busses. The target speed is 300 MHz with a theoretical bandwidth of 10.8 Gbps for
Port A and 21.6 Gbps for Port B (total bandwidth of 32.4 Gbps or 64.8 Gbps for
simultaneous read and write).
Table 2–37 lists the pin assignments for the QDR II interface and their corresponding
schematic signal names and Stratix V GX pin numbers.
