Detailed Description
User Test I/O
[
Figure 1-2
, callout

]
A standard 2 x 6, 100-mil pitch header (J197) brings out 6 FPGA I/O for test purposes.
Table 1-12
lists these pins.
GTX Transceiver Pins
[
Figure 1-2
, callout

]
All FPGA GTX transceiver pins are connected to differential SMA connector pairs. The
GTX transceivers are grouped into five sets of four (referred to as
Quads)
which share two
differential reference clock pin pairs (
Figure 1-7
). The transceiver pins and their
corresponding SMA connector are shown in
Table 1-13
.
