  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.
  3. Use IBIS to determine any duty-cycle distortion incurred using various standards.

  1. This parameter indicates the total sampling error of the Zynq UltraScale+ RFSoC DDR input registers, measured across voltage, temperature, and process. The measurement methodology uses the MMCM to capture the edges of operation of the DDR input registers. 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.
  2. This parameter is the receive sampling error for RX_BITSLICE when using dynamic phase alignment.
  3. This parameter is the receive sampling error for RX_BITSLICE when using built-in self-calibration (BISC).

  1. Input_logic_uncertainty accounts for the setup/hold and any pattern dependent jitter for the input logic (input register, IDDRE1, or ISERDESE3).
  2. Calibration error associated with quantization effects based on the IDELAY resolution. Calibration must be performed for each input pin to ensure optimal performance.
