Programmable oscillators are widely used in many fields. Their working principles and applications range from frequency synchronization and clock generation in computer systems to phase-locked loop (PLL) frequency synthesis, timekeeping and phase modulation in high-frequency applications and industrial control. One such oscillator is the SIT8008BIU2-28N oscillator.

The SIT8008BIU2-28N oscillator is an 8 pin SMD quartz crystal clock oscillator with an output frequency of 28.3333MHz. It has a low frequency stability of 0.5ppm, an operating frequency range of 16.777MHz to 65.535MHz and an output frequency range of 20MHz to 80MHz. The SIT8008BIU2-28N oscillator is designed specifically for frequency synchronization and clock generation in computer systems and embedded systems, providing low jitter performance and consistent frequency across temperature and voltage ranges.

The working principle of the SIT8008BIU2-28N oscillator is based on the use of a quartz crystal as the resonating element. A quartz crystal is a natural mineral composed of crystallized silicon dioxide, which has the properties of piezoelectricity and electrostriction. When an alternating voltage of the same frequency as its natural resonant frequency is applied to a quartz crystal, it will oscillate and generate a predictable and consistent frequency. This frequency can be adjusted by changing the input voltage and drive strength.

In the SIT8008BIU2-28N oscillator, the quartz crystal is placed in an oscillator circuit and connected to a ceramic resonator, usually with a driver circuit. The oscillator circuit is then connected to a voltage-controlled oscillator (VCO) to generate a clock signal with a predictable and consistent frequency. This frequency is determined by the external components and the chosen crystal. The SIT8008BIU2-28N can also be programmed to operate at any of its available frequencies, including 28.3333MHz, through a programmable software interface.

The SIT8008BIU2-28N oscillator offers low jitter performance, making it ideal for applications where precise timekeeping is needed. It is also capable of operating across temperature and voltage ranges, which makes it suitable for use in rugged and harsh environments. The SIT8008BIU2-28N is used in a variety of applications, including:

• Frequency synchronization and clock generation in computer systems
• Phase-locked loop (PLL) frequency synthesis
• Stable timekeeping
• Phase modulation
• Industrial control

Overall, the SIT8008BIU2-28N oscillator is a highly reliable and versatile device, which can be used in a variety of applications. With its low jitter performance and wide operating frequency range, the SIT8008BIU2-28N is ideal for precise frequency synchronisation and clock generation. It is also suitable for phase-locked loop (PLL) frequency synthesis, timekeeping and phase modulation in higher frequency applications and industrial control systems.
