From Internal
Registers
The Arria GX 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 to meet DDR SDRAM timing
requirements.
In addition to the six I/O registers in each IOE, Arria GX devices also have dedicated
phase-shift circuitry for interfacing with external memory interfaces, including DDR,
DDR2 SDRAM, and SDR SDRAM. In every Arria GX 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.
A compensated delay element on each DQS pin automatically aligns input DQS
synchronization signals with the data window of their corresponding DQ data
signals. The DQS signals drive a local DQS bus in the top and bottom I/O banks. This
DQS bus is an additional resource to the I/O clocks and is used to clock DQ input
registers with the DQS signal.
