82V3280APFG Application Field and Working Principle

Introduction

The 82V3280APFG is a versatile silicon-on-insulator (SOI) clock/timing device for integration within a variety of systems for time-critical, mission-critical, and hazardous environments. Ideal for applications that require a reliable reference clock, the 82V3280APFG offers low-jitter performance, low power consumption, robust frequency stability, and many other features. It is suitable for a range of application fields including industrial control, medical, aerospace, and defense.

Application Fields

The 82V3280APFG is designed for use in a variety of application fields. In industrial control, it can be used as a highly accurate, reliable reference clock for anything from simple controller systems to high-speed, high-throughput electronics. In medical applications, the 82V3280APFG can provide dependable timing and synchronization to aid in patient monitoring and diagnostics. In aerospace and defense applications, the device can be used to provide secure, reliable synchronization of onboard electronics in extremely harsh environments.

The device is also a great choice for time-sensitive networks, including high-speed Ethernet and Fibre Channel systems, as well as for time-critical applications requiring extreme speed, such as financial networks and data centers. And its low-power operation makes it ideal for mobile applications, such as smartphones and tablets.

Working Principle

The 82V3280APFG is a silicon-on-insulator (SOI) clock/timing device that works in conjunction with external power, crystal oscillator, and resistors to generate a low-jitter, low-phase-noise reference clock. The device contains a temperature-compensated oscillator with a frequency range of 10 MHz to 400 MHz. The internal oscillator generates an internal reference clock that is used to generate the output clock signals. The output clocks are then sent to the appropriate pins.

In terms of timing accuracy, the 82V3280APFG utilizes two different synchronization techniques: digital frequency synthesizer (DFS) and phase-locked loop (PLL). DFS allows for more accurate tuning of low-frequency clocks, while PLL is used to fine-tune higher frequency clocks. These two methods allow for accurate control of the output clock frequency and provide better jitter performance than other clock/timing devices.

The 82V3280APFG also incorporates several advanced features to minimize power consumption and improve overall performance. It is manufactured on a low-power, low-voltage SOI process, and has on-chip decoupling capacitors for improved power-supply noise reduction. Its low-power options are also ideal for high-end system designs.

In addition, the device offers advanced features to protect against EMI, temperature drift, and excessive power supply noise. It also provides redundant offline clock mode to ensure a stable and reliable clock output, even in the event of an unexpected glitch in the power supply.

Conclusion

The 82V3280APFG from STMicroelectronics is a versatile clock/timing device for mission-critical, time-sensitive, and hazardous applications. Its low-jitter, low-power performance makes it ideal for a wide range of applications, including industrial control, medical, aerospace, defense, and many others. The device’s advanced features—such as its temperature-compensated oscillator and robust frequency stability—also make it a dependable choice for synchronization of onboard electronics or other complex timing applications.
