The working principle of the 500DJAC70M0000ACF is based on a ceramic resonator and an external crystal. The ceramic resonator consists of two elements that vibrate in response to an alternating current (AC) signal; this resonant frequency is determined by the physical properties of the elements and the surrounding environment. The external crystal works similarly but is typically more accurate and stable over a wider temperature range due to its low tolerance to various parameters. An irregular voltage (also known as the drive voltage) is applied to the crystal in order to produce an energy output at the desired frequency. This output is then amplified and passed through a buffer before being output as a clean sinusoidal waveform.

In summary, the 500DJAC70M0000ACF oscillator is a versatile, low jitter, low power device used in various applications. With its frequency stability and high reliability it is suitable for a range of applications such as Clock and Data Recovery, telecom clocks, switching/routing, storage and networking. It works based on a ceramic resonator and an external crystal where an irregular voltage is applied to produce a sinusoidal waveform output with minimal jitter.
