The setup and hold-time specifications assume that the
parallel clock-input signal (PCLKI) and parallel-data
input signal (PDI_) are from the same source. They
should have identical common-mode voltages, signal
amplitudes, and slew rates. If PCLKI and PDI_ differ
significantly, the setup and hold-time requirements
must be modified to account for these differences.
Define t
time requirement when there are significant differences
between PCLKI and PDI_.
