NOTES:
1.
tPNactual – tPMactual 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, VCC, loading, etc.). tSK (0) compares tPLH on a given path to tPLH
on any other path or compares tPHL on a given path to tPHL on any other path.
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).
