CLK
The Stratix II IOE operates in bidirectional DDR mode by combining the
DDR input and DDR output configurations. The negative-edge-clocked
OE register holds the OE signal inactive until the falling edge of the clock.
This is done to meet DDR SDRAM timing requirements.
External RAM Interfacing
In addition to the six I/O registers in each IOE, Stratix II devices also have
dedicated phase-shift circuitry for interfacing with external memory
interfaces. Stratix II devices support DDR and DDR2 SDRAM, QDR II
SRAM, RLDRAM II, and SDR SDRAM memory interfaces. In every
Stratix II device, the I/O banks at the top (banks 3 and 4) and bottom
(banks 7 and 8) of the device support DQ and DQS signals with DQ bus
modes of ×4, ×8/×9, ×16/×18, or ×32/×36.
of DQ and DQS buses that are supported per device.
