Device
Each DQ group consists of a DQS pin, DM pin, and up to nine DQ pins.
This is an idealized pin layout. For actual pin layout, refer to the pin table.

Package
Cyclone II devices support the data strobe or read clock signal (DQS)
used in DDR and DDR2 SDRAM. Cyclone II devices can use either
bidirectional data strobes or unidirectional read clocks. The dedicated
external memory interface in Cyclone II devices also includes
programmable delay circuitry that can shift the incoming DQS signals to
center align the DQS signals within the data window.
The DQS signal is usually associated with a group of data (DQ) pins. The
phase-shifted DQS signals drive the global clock network, which is used
to clock the DQ signals on internal LE registers.
