Reference Manual

Table 2–47 lists the SDI connector component reference and manufacturing

information.

40G QSFP Connector

The development board has a 40G QSFP connector that uses four transceiver channels

from the Stratix V GX FPGA device. These modules takes in serial data from the

Stratix V GX FPGA device and transform them to optical signals. The board includes a

cage assembly for the QSFP connector.

Table 2–48 summarizes the QSFP connector pin assignments, signal names, and

functions.
