Notes:
1.
Refers to transition on noninverting output in PLL bypass mode.
2.
While the pulse skew is almost constant over frequency, the duty cycle error increases at
higher frequencies. This is due to the formula: duty cycle=twH/tc, were the cycle (tc)
decreases as the frequency goes up.
3.
Switching characteristics guaranteed for application frequency range.
4.
Static phase offset shifted by design.
