PMA Features
PMA Features
To prevent core and I/O noise from coupling into the transceivers, the PMA block is isolated from the rest
of the chip—ensuring optimal signal integrity. For the transceivers, you can use the channel PLL of an unused
receiver PMA as an additional transmit PLL.

operation of other channels
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.
