Differential Sma Mrcc Pin Inputs; Superclock-2 Module - Xilinx KCU1250 User Manual

Differential SMA MRCC Pin Inputs

The KCU1250 board provides two pairs of differential SMA transceiver clock inputs (callout
32, Figure 1-2) that can be used for connecting to an external clock source. The FPGA MRCC
pins are connected to the SMA connectors as shown in
Table 1-10: Differential SMA Clock Connections

SuperClock-2 Module

The SuperClock-2 module (callout 10,
connector (J36) and provides a programmable, low-noise and low-jitter clock source for the
KCU1250 board (see SuperClock-2 Module User Guide (UG770)
maps to FPGA I/O by way of 14 control pins, 2 LVDS pairs, 1 regional clock pair, and 1 reset
pin. Table 1-11
KCU1250 board supplies UTIL_5V0, UTIL_3V3, UTIL_2V5, and V
clock module interface.
