Figure 3‐30: KCU116 SYSMON and SYSMON Header J93 Voltage Source Options
The KCU116 board supports both the internal FPGA sensor measurements and the external
measurement capabilities of the SYSMON. Internal measurements of the die temperature,

external differential voltage reference (SYSMON_VREFP) or on-chip voltage reference
(jumper J90 2-3) for the analog-to-digital converter.
For external measurements the SYSMON header (J93) is provided. This header can be used
to provide analog inputs to the FPGA's dedicated VP/VN input channel. The
VCCINT_VIN_R_P/N signals from the V
resistor R36 are also made available at J93 pins 11 and 12.
