Introduction

Programmable Oscillators are devices used to control the frequency, or oscillation rate of electronic signals. These devices are typically used in Test and Measurement, Automotive, Machine Control and Industrial applications, as well as applications requiring high precision analog control. Programmable Oscillators come in a variety of configurations, including crystal oscillators and programmable digital oscillators. Many of these devices can be programmed to a specific required frequency, or set up with a variety of options, such as frequency range, start/stop frequency, enable/disable control, gate width and different types of triggering. In this article, we will be exploring the 500SABD-ACH programmable oscillator, their application field and working principle.

Overview of the 500SABD-ACH

The 500SABD-ACH is a programmable oscillator with a wide frequency range, from 5MHz to 250MHz, and a frequency stability of ±100ppm/°C. It has a crystal accuracy of ±100ppm, and a maximum output power of +5dBm (at 500MHz).The 500SABD-ACH can be programmed using a variety of methods, including bus-controlled programming, BCD switch settings, and a serial interface. It also has an adjustable start/stop frequency, gate width control, and a programmable output impedance.The 500SABD-ACH can be used in applications such as frequency synthesis, phase-locked loops, reference clocks, modulators, demodulators, and frequency converters. It can also be used in electronic measurement and test equipment, RF communication systems, and automated machinery control.

Working Principle

The working principle of a programmable oscillator is based on the fact that it is designed to generate an oscillating electrical signal with a specific frequency. The electrical signal is generated by controlling the flow of electricity through a series of interconnected components, including a crystal oscillator, phase-locked loop circuits, counters, and a frequency divider.The crystal oscillator is the main component in the oscillator circuit and is responsible for producing an oscillating signal of the specified frequency. The phase-locked loop circuit is used to maintain the frequency of the signal, while the counter and frequency divider are used to divide the signal into the desired frequency.When the output frequency is changed, the oscillator frequency is changed by adjusting the frequency of the crystal oscillator. This is done by changing the voltage applied to the crystal oscillator\'s electrodes, which will cause the crystal to vibrate at a different frequency.

Conclusion

The 500SABD-ACH is a programmable oscillator which can be used for a variety of applications. It has a wide frequency range and a stability of ±100ppm/°C. It can be programmed using a variety of methods and has adjustable start/stop frequency and gate width control.The working principle of a programmable oscillator involves using a crystal oscillator, phase-locked loop circuit, counter and frequency divider to generate a specific frequency. The frequency can be adjusted by changing the voltage applied to the crystal oscillator\'s electrodes, which will cause the crystal to vibrate at a different frequency.This article has provided an overview of the 500SABD-ACH and its application field and working principle.
