SERDES SMPTE Channels
Note: SERDES SMPTE channels are available only for the LFE2M50E-FF672 (or larger) device.
(see Appendix A, Figure 9)
A single-channel 75-ohm SERDES channel is connected to B
N
C edge connectors. These connections are pro-
vided to connect to SMPTE video equipment. The channels include the appropriate passive components for
interoperability to SMPTE devices.

SERDES PCI Express Channels
(see Appendix A, Figure 9)
This board is equipped to communicate directly as an add-on card to a PCI Express host. It is designed with edge
fingers (C
N
1) to fit directly into an x4 host receptacle. Power can be supplied directly from the PCI Express host via
the edge finger connections.
FPGA Test Pins
(see Appendix A, Figure 14)
General-purpose FPGA pins are available for user applications. FPGA pins are connected to switches and LEDS
designated according to the following table.
