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 3, 4, 6, 7, 8, or 10 by using the
Quartus II software. You can bypass the Stratix IV deserializer in the Quartus II
MegaWizard Plug-In Manager software to support DDR (×2) or SDR (×1) operations,
as shown
deserializer is bypassed. The IOE contains two data input registers that can operate in
DDR or SDR mode.
The Stratix IV device family supports three receiver datapath modes—non-DPA
mode, DPA mode, and soft-CDR mode.

and synchronizer blocks are disabled. Input serial data is registered at the rising or
falling edge of the serial LVDS_diffioclk clock produced by the left and right PLL.
You can select the rising/falling edge option using the ALTLDVS MegaWizard
Plug-In Manager software. Both data realignment and deserializer blocks are clocked
by the LVDS_diffioclk clock, which is generated by the left and right PLL.
