SFP+
The Arria 10 GX FPGA development board includes one SFP+ module that uses transceiver channels
from the FPGA. This module takes in serial data from the FPGA and transform them into optical signals.
The Arria 10 GX FPGA development board includes one SFP+ cage assembly for the SFP+ port that is
used by the device.

C supports communication between integrated circuits on a board. It is a simple two-wire bus that
consists of a serial data line (SDA) and a serial clock (SCL). The MAX V and Arria 10 devices use the I
2
C
for reading and writing to the character LCD. You can use the Arria 10 or MAX V as the I
2
C host to
access the PLLs and clocks.
