WebMay 17, 2024 · Clock jitter is typically caused by the generator circuitry, thermal noise, power supply variations, and interference coupled from nearby circuits. As the data speeds increase with each generation of PCIe bus, so does the potential for jitter. Yet, the actual jitter specification for the clock is constantly lowered to meet speed and timing issues. WebPhase jitter: Defined as the undesired deviation from an ideal periodic timing signal. The Renesas low-jitter clocks offer typical RMS phase jitter of less than 700 fs, with some lower than 300fs for very high …

WebFeb 14, 2024 · This is especially true in operations that require precise timing. Phase noise and jitter are two common culprits that affect the system clock performance in circuits, so they must be considered when designing and building boards. Engineers must understand phase noise and jitter to mitigate their effect on timing-critical circuitry. WebJul 17, 2012 · Not all clock phase noise transfers to the line output, but the bandwidth of phase noise over which clock jitter is measured often depends heavily or entirely on the clock. For this reason, clock selection can make the difference between meeting the output jitter budget—or failing. AFM vs. PLL
