When calculating the timing budgets, one may need to consider the worst-case static phase offset, duty cycle error, cycle-to-cycle jitter, and possibly tracking jitter from the PLL, the worst-case skew and jitter from the clock distribution, and the worst-case setup, hold, and clock-to-output times for the clocked elements.
