Removed I/O banks 5A and 5B from Cyclone V SE A2 and A4, and
Cyclone V SX C2 and C4 in the table that lists the reference clock pin
for I/O banks without dedicated reference clock pin. These devices do
not have I/O bank 5B.
Added the M301 and M383 packages to the modular I/O banks tables
for Cyclone V GX C4 device.
Added the number of true LVDS buffers for the M301 and M383
packages of the Cyclone V GX C4 device.
Added a figure that shows the phase relationship for the external PLL
interface signals.
Clarified that you can only use R
Removed all "preliminary" marks.
Added link to Knowledge Base article that clarifies about vertical
migration (drop-in compatibility).
Clarified that "internal PLL option" refers to the option in the ALTLVDS
megafunction.
Updated the topic about emulated LVDS buffers to clarify that you can
use unutilized true LVDS input channels (instead of "buffers") as
emulated LVDS output buffers.
2013.06.21 Updated the figure about data realignment timing to correct the data pattern
after a bit slip.
2013.06.17 Removed 3.3 V input signal for 2.5 V V
MultiVolt I/O support.
Added a topic about LVDS I/O restrictions and differential pad
placement rule.
Updated the preliminary I/O counts per bank for the following packages:
M301 packages of Cyclone V GX C5 and GT D5 devices.
U324 package of Cyclone V GX C3 device.
M383 packages of Cyclone V E A5, GX C5, and GT D5 devices.
M484 packages of Cyclone V E A7, GX C7, and GT D7 devices.
U484 packages of Cyclone V E A9, GX C9, and GT D9 devices.
F1152 packages of Cyclone V GX C9 and GT D9 devices.
Updated the preliminary LVDS channels counts for the M301 and M383
packages of Cyclone V E, GX, and GT devices.
Added the preliminary LVDS channels counts for Cyclone V SE, SX,
and ST devices.
