2. Arria GX Architecture
AGX51002-1.3
Arria™ GX devices incorporate up to 12 high-speed serial transceiver
channels that build on the success of the Stratix® II GX device family.
Arria GX transceivers are structured into full-duplex (transmitter and
receiver) four-channel groups called transceiver blocks located on the
right side of the device. The transceiver blocks can be configured to
support the following serial connectivity protocols (functional modes):
Transceivers

PCI Express (PIPE)
Gigabit Ethernet (GIGE)
XAUI
Basic (600 Mbps to 3.125 Gbps)
SDI (HD, 3G)
Serial RapidIO (1.25 Gbps, 2.5 Gbps, 3.125 Gbps)
Transceivers within each block are independent and have their own set of
dividers. Therefore, each transceiver can operate at different frequencies.
Each block can select from two reference clocks to provide two clock
domains that each transceiver can select from.
Table 2–1 shows the number of transceiver channels for each member of
the Arria GX family.
