In case of such an application using the Si4x6x chip revisions other than C (e.g., B0 or B1), there are optimized ... Webclock buffers distributed very nonuniformly over the chip. E. Jitter Undesired variations in the cycle period are called jitter. Jitter reduces performance because some cycles are short, and the chip frequency must be slowed to avoid long-path errors. Gen-erally, a phase-locked loop (PLL) is used to generate a low-jitter
