4.4. 10GBASE-R

Arria V GT and ST devices support 10GBASE-R in PMA direct mode using soft PCS. 10GBASE-R is a specific physical layer implementation of the 10 Gigabit Ethernet link defined in clause 49 of the IEEE 802.3-2008 specification. The 10GBASE-R PHY uses the XGMII interface to connect to the IEEE802.3 media access control (MAC) and reconciliation sublayer (RS). The IEEE 802.3-2008 specification requires each 10GBASE-R link to support a 10 Gbps data rate at the XGMII interface and a 10.3125 Gbps serial line rate with 64B/66B encoding.

The 10-Gbps transceivers transmitter in Arria V GT and ST devices are compliant with the 10GBASE-KR specification under the following conditions:

  • A maximum of three full duplex channels within a bank are used. These three channels do not include a CMU PLL.
  • The transmitted signal is 64B/66B encoded.

To implement a 10GBASE-R link, instantiate the 10GBASE-R PHY IP core in the IP Catalog, under Ethernet in the Interfaces menu.
