In synchronous digital systems, timing is not just a performance parameter but a functional requirement. Processors, communication interfaces, memory devices, and high-speed peripherals all rely on stable clock signals to operate correctly. If clock timing drifts, has excessive jitter, or is not aligned properly between devices, system behavior can become unpredictable. Data errors, communication failure, or complete system instability can occur. Clock generator ICs solve this by producing accurate and stable timing signals required by different system blocks.
