for any data input to output path compared to any other data input to output path where N and M are either LH or
HL. Skew times are valid only under same test conditions (temperature, V
CC
, loading, etc.).
2. t
SK
(p) is used to quantify duty cycle characteristics. In essence it compares the input signal duty cycle to the corresponding output signal
duty cycle (50MHz input frequency and 50% duty cycle, tested on data paths only).
