"The increasing demand for performance-intensive handheld devices and rising time-to-market pressures heightens the need for design turnkey providers to endow ASIC customers with more predictable and robust SoC solutions. With True Circuits' PLL and DLL at TSMC 55nm, we were able to achieve low jitter for DDR 800Mbps and enter into mass production with very stable yield."

The cycle-to-cycle jitter for a divided output clock is the same percentage of the divided clock period as that for an undivided clock in the worst case of low-frequency supply/substrate noise. However, the cycle-to-cycle jitter for any divided clock expressed in units of time cannot exceed twice the long-term jitter by their definitions.
