"We selected TCI's clock generator PLL because of its small size, wide frequency range and superior low-jitter performance. This will enable our ASIC customers to successfully implement multiple SPI-4.2 macros in their high-end telecommunication ASICs and help meet the tight jitter and power budgets required for 10 Gbps SONET/SDH systems."

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.
