The Stratix IV GT transceiver architecture has the following components:
■
■
■
Four transceiver channels and two CMU channels are located in each transceiver
block on the left and right sides of the device. Each Stratix IV GT device also has two
10G ATX PLLs that support data rates between 9.9 Gbps and 11.3 Gbps. Additionally,
each Stratix IV GT device has two 6G ATX PLLs that support data rates between
600 Mbps and 6.5 Gbps, except the EP4S100G5F45 device that has four 6G ATX PLLs.
The 6G ATX PLL does not support all data rates between 600 Mbps and 6.5 Gbps.

Each transceiver channel consists of the:
■
■
Each transceiver channel interfaces to either the PCIe hard IP block (PCIe hard
IP-transceiver interface) or directly to the FPGA fabric (FPGA fabric-transceiver
interface). The transceiver channel interfaces to the PCIe hard IP block if the hard IP
block is used to implement the PCIe PHY MAC, data link layer, and transaction layer.
Otherwise, the transceiver channel interfaces directly to the FPGA fabric.
