Clock generators and synthesizers are integral components of many electrical systems. They produce clean output clocks with exact frequencies. The clock provides a time reference for a system. This allows events to occur synchronously and at expected intervals, which is critical for many system functions, including data transfer.
The frequency of the generated clock may be fixed, or adjustable by an analogue voltage or digital control word. The term ‘synthesizer’ is often used for devices that can produce multiple clock frequencies over a specified range with a known reference clock. At the core of the clock generator is an oscillator that resonates when energy is supplied to it. The oscillator may be mechanical such as a crystal oscillator, or electrical such as an inductor-capacitor (IC) tank resonator.
