What is a Jitter Cleaner?
Jitter cleaners, also known as jitter attenuators, reduce the magnitude of noise (jitter) on a given timing signal. Jitter is the undesired deviation from an ideal periodic timing signal—commonly seen in the phase, or amplitude of successive pulses, and/or frequency changes in a specific timeframe. High jitter levels are often caused by long traces, cabling, and noisy system environments. Excessive jitter levels lead to undesired system behavior in high-performance applications.
Renesas jitter cleaners use stable reference sources and innovative control circuitry to lock onto the phase and average frequency of a noisy clock signal. They then output a high-quality (low jitter) signal to be sourced to downstream devices within the clock network.
