Specifications

ChangesVersionDate
• Added the preliminary LVDS channels counts for Cyclone V SE, SX,
and ST devices.
• Updated the topic about LVDS input R
D
OCT to remove the require-
ment for setting the V
CCIO
to 2.5 V. R
D
OCT now requires only that the
V
CCPD
is 2.5 V.
• Updated the topic about LVPECL termination to improve clarity.
• Moved all links in all topics to the Related Information section for easy
reference.
• Added link to the known document issues in the Knowledge Base.
• Updated the M386 package to M383.
• Updated the M383 package plan of the Cyclone V E device.
2013.05.06May 2013
• Updated the GPIO count for the M301 package of the Cyclone V GX
devices.
• Updated the HPS I/O counts for Cyclone V SE, SX, and ST devices.
• Updated the I/O vertical migration table.
• Corrected the note in the MultiVolt I/O interface topic.
• Updated the 3.3 V LVTTL programmable current strength values to
add 16 mA current strength.
• Removed statements indicating that the clock tree network cannot cross
over to different I/O regions.
•
Removed references to rx_syncclock port because the port does
not apply to Cyclone V devices.
• Added Bank 1A to the I/O banks location figure for Cyclone V E devices
because it is now available for the Cyclone V E A2 and A4 devices.
• Added the M383 and M484 packages to the modular I/O banks tables
for Cyclone V E devices, and added the U484 package for the Cyclone V
E A9 device.
• Added the U324, M301, M383, and M484 to the modular I/O banks
tables for the Cyclone V GX devices, and added the U484 package for
the Cyclone V GX C9 device.
• Added the M301, M383, and M484 to the modular I/O banks tables for
the Cyclone V GT devices, and added the U484 package for the
Cyclone V GT D9 device.
• Added notes to clarify the HPS row and column I/O counts in the
modular I/O banks tables for the Cyclone V SE, SX, and ST devices.
• Changed the color of the transceiver blocks in the high-speed differential
I/O location diagrams for clarity.
• Repaired the diagram for the example of calibrating multiple I/O banks
with a shared OCT calibration block for readability.
• Added a topic about emulated LVDS buffers.
• Edited the topic about true LVDS buffers.
