As such, it is suitable for use in a wide variety of embedded systems, including medical and military applications that require precision timing. Other applications include automotive control systems, industrial automation, and data acquisition systems.

Features and Benefits

In addition to its extended frequency range, the 591BC435M000DGR Oscillator offers some unique features and benefits, including:

• High reliability: Designed to provide minimal drift and highest tolerance for temperature and supply voltage changes.
• Precision control: Specified stability of ±10 PPM over an operating range of -40°C to +85°C for reliable output.
• Low power consumption: Fully integrated circuits with ultra-low power consumption facilitate excellent energy efficiency.
• Compact size: Compact DIL package with small size allows freedom for product design.

Operating Principle

The 591BC435M000DGR Oscillator operates by using an Electronic Tuned Oscillator (ETO) circuit. This circuit consists of an oscillator stage, a frequency control section, and a stability circuit. The oscillator stage consists of an electronic tunable oscillator, an amplifier, and an output buffer. The frequency control section uses a combination of varicap diodes and circuit capacitors to provide precise control of the oscillator frequency. The stability circuit is used to reduce the effects of temperature and supply voltage changes. With this design, the 591BC435M000DGR Oscillator can achieve stable performance over a wide range of temperatures and voltage conditions.

Conclusion

The 591BC435M000DGR Oscillator is a highly reliable and accurate device that offers extended frequency range, high reliability, and low power consumption. Its DIL package and compact size make it ideal for use in embedded systems and automated applications. With its wide range of features and benefits, the 591BC435M000DGR Oscillator is an excellent choice for any application that requires precise timing and reliable performance.
