Measured with 100mV input swing. See “Timing Diagrams” section for definition of parameters. High-frequency AC-parameters are
guaranteed by design and characterization.
Within-bank skew is the difference in propagation delays among the outputs within the same bank.
Bank-to-bank skew is the difference in propagation delays between outputs from different banks. Bank-to-bank skew is also the phase
offset between each bank, after MR is applied.
