Device
These maximum clock rates apply if the Stratix device uses DQS phase-shift circuitry to interface with DDR
SDRAM. DQS phase-shift circuitry is only available in the top and bottom I/O banks (I/O banks 3, 4, 7, and 8).
For more information on DDR SDRAM, see AN 342: Interfacing DDR SDRAM with Stratix & Stratix GX Devices.
DDR SDRAM is supported on the Stratix device side I/O banks (I/O banks 1, 2, 5, and 6) without dedicated DQS
phase-shift circuitry. The read DQS signal is ignored in this mode. Numbers are preliminary.
For more information on QDR or QDRII SRAM, see AN 349: QDR SRAM Controller Reference Design for Stratix &
Stratix GX Devices.

Package
In addition to six I/O registers and one input latch in the IOE for
interfacing to these high-speed memory interfaces, Stratix devices also
have dedicated circuitry for interfacing with DDR SDRAM. In every
Stratix device, the I/O banks at the top (I/O banks 3 and 4) and bottom
(I/O banks 7 and 8) of the device support DDR SDRAM up to 200 MHz.
These pins support DQS signals with DQ bus modes of ×8, ×16, or ×32.
