Skew times are valid only under same test conditions (temperature, VCC, loading, etc.). 2. tSK(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).
