Figure 6–16. Stratix V Deserializer Bypass
Notes to
(1) All disabled blocks and signals are grayed out.
(2) In DDR mode, rx_inclock clocks the IOE register. In SDR mode, data is directly passed through the IOE.
(3) In SDR and DDR modes, the data width from the IOE is 1 and 2 bits, respectively.

Deserializer
You can statically set the deserialization factor to x3, x4, x5, x6, x7, x8, x9, or x10 by
using the Quartus II software. You can bypass the Stratix V deserializer in the
Quartus II MegaWizard Plug-In Manager to support DDR (x2) or SDR (x1) operations,
as shown
deserializer is bypassed. The IOE contains two data input registers that can operate in
DDR or SDR mode.
