Part 2.3.2: 125MHz Active Differential Crystal
G2 in Figure 2-3-3 is the 125MHz active differential crystal, which is the
reference input clock provided to the GTP module inside the FPGA. The crystal
output is connected to the GTP BANK216 clock pins MGTREFCLK0P (F6) and
MGTREFCLK0N (E6) of the FPGA.
