User SMA MGT Clock
[Figure 2-1, callout 42]
The ZCU102 board provides a pair of SMAs for differential AC coupled user MGT clock input
into FPGA U1 MGTH bank 129. This differential signal pair is series-capacitor coupled. The
P-side SMA J79 signal USER_SMA_MGT_CLOCK_P is connected to U1 MGTREFCLK0P pin J27,
with the N-side SMA J80 signal USER_SMA_MGT_CLOCK_N connected to U1 MGTREFCLK0N
pin J28. The user SMA MGT clock circuit is shown in Figure 3-11.
