Notes:
1. Setup and hold times are measured over worst case conditions (process, voltage, temperature). Setup time is measured
relative to the global clock input signal using the slowest process, slowest temperature, and slowest voltage. Hold time is
measured relative to the global clock input signal using the fastest process, fastest temperature, and fastest voltage.
2. This table lists representative values where one global clock input drives one vertical clock line in each accessible column,
and where all accessible I/O and CLB flip-flops are clocked by the global clock net in a single SLR.
3. Use IBIS to determine any duty-cycle distortion incurred using various standards.

Notes:
1. This parameter indicates the total sampling error of the Kintex UltraScale FPGAs DDR input registers, measured across
voltage, temperature, and process. The characterization methodology uses the MMCM to capture the DDR input registers’
edges of operation. These measurements include: CLK0 MMCM jitter, MMCM accuracy (phase offset), and MMCM phase
shift resolution. These measurements do not include package or clock tree skew.
