2. Arria GX Architecture
AGX51002-2.0
Transceivers
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. You can configure the
transceiver blocks to support the following serial connectivity protocols
(functional modes):
■
■
■
■
■
■
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 lists the number of transceiver channels for each member of the Arria GX
family.
