The Altera 10GBASE-R PHY IP Core implements the functionality described in IEEE Standard 802.3
Clause 45.
It delivers serialized data to an optical module that drives optical fiber at a line rate of 10.3125 gigabits per
second (Gbps). In a multi-channel implementation of 10GBASE-R, each channel of the 10GBASE-R PHY
IP Core operates independently. Both the PCS and PMA of the 10GBASE-R PHY are implemented as
hard IP blocks in Stratix V devices, saving FPGA resources.

Note: For a 10-Gbps Ethernet solution that includes both the Ethernet MAC and the 10GBASE-R PHY,
refer to the 10-Gbps Ethernet MAC MegaCore Function User Guide.
Note: For more detailed information about the 10GBASE-R transceiver channel datapath, clocking, and
channel placement, refer to the “10GBASE-R” section in the Transceiver Configurations in Stratix V
Devices chapter of the Stratix V Device Handbook.
The following figure illustrates a multiple 10 GbE channel IP core in a Stratix IV GT device. To achieve
higher bandwidths, you can instantiate multiple channels. The PCS is available in soft logic for Stratix IV
GT devices; it connects to a separately instantiated hard PMA. The PCS connects to an Ethernet MAC via
single data rate (SDR) XGMII running at 156.25 megabits per second (Mbps) and transmits data to a 10
Gbps transceiver PMA running at 10.3125 Gbps in a Stratix IV GT device.
