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.).

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).
