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.
