1.12.3. PCS Features

The Arria® V core logic connects to the PCS through an 8, 10, 16, 20, 32, 40, 64, 66, or 67 bit interface, depending on the transceiver data rate and protocol. Arria® V devices contain PCS hard IP to support PCIe Gen1, Gen2, and Gen3, GbE, Serial RapidIO® (SRIO), GPON, and CPRI.

All other standard and proprietary protocols within the following speed ranges are also supported:

  • 611 Mbps to 6.5536 Gbps—supported through the custom double-width mode (up to 6.5536 Gbps) and custom single-width mode (up to 3.75 Gbps) of the transceiver PCS hard IP.
  • 6.5536 Gbps to 10.3125 Gbps—supported through dedicated 80 or 64 bit interface that bypass the PCS hard IP and connects the PMA directly to the core logic. In Arria® V GZ, this is supported in the transceiver PCS hard IP.
