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 clocks DQ input registers with the DQS signal.
Two separate single phase-shifting reference circuits are located on the
top and bottom of the Stratix GX device. Each circuit is driven by a system
reference clock through the CLK pins that is the same frequency as the
DQS signal. Clock pins CLK[15..12]p feed the phase-shift circuitry on
the top of the device and clock pins CLK[7..4]p feed the phase-shift
circuitry on the bottom of the device. The phase-shifting reference circuit
on the top of the device controls the compensated delay elements for all
10 DQS pins located at the top of the device. The phase-shifting reference
circuit on the bottom of the device controls the compensated delay
elements for all 10 DQS pins located on the bottom of the device. All
10 delay elements (DQS signals) on either the top or bottom of the device
shift by the same degree amount. For example, all 10 DQS pins on the top
of the device can be shifted by 90° and all 10 DQS pins on the bottom of
the device can be shifted by 72°. The reference circuits require a maximum
of 256 system reference clock cycles to set the correct phase on the DQS
delay elements.

is duplicated on the bottom of the device.
