Description

Device family

Stratix V
Arria V GZ
Arria V GX
Arria V GT
Arria V SX
Arria V ST

Supports all Arria V and Stratix V

devices.

Number of lanes

1, 2, 4, 8

The total number of duplex lanes.

Protocol version

Gen1 (2.5 Gbps)
Gen2 (5.0 Gbps)
Gen3 (8.0 Gbps)

The Gen1 and Gen2 implement the

Intel PHY Interface for PCI Express

(PIPE) Architecture PCI Express 2.0

specification. The Gen3 implements

the PHY Interface for the PCI Express

Architecture PCI Express 3.0 specifi‐

cation.

Gen1 and Gen2 base data rate

1 × Lane rate
2 × Lane rate
4 × Lane rate
8 ×Lane rate

The base data rate is the output clock

frequency of the TX PLL. Select a

base data rate that minimizes the

number of PLLs required to generate

all the clocks required for data

transmission.

Data rate

2500 Mbps
5000 Mbps
8000 Mbps

Specifies the data rate. This

parameter is based on the Protocol

version you specify. You cannot
