is the rise time from LOW of all clocks to HIGH of all clocks (Fig.3) including rise time, skew and jitter
components. Measurements taken between 0.6 V and 2.6 V. Skew between two LLx clocks will not deviate more
than
±
2 ns if output loads are matched within 20%.
MS and LFCO2 functions not tested.
