595AG000244DG

Oscillators are fundamental to electronic systems, providing source of sine or square waves. 595AG000244DG oscillator is one typical type and this article will mainly focus on explaining its application field and working principle.

Application Field

595AG000244DG oscillator is generally used to replace the quartz clock crystal and other oscillator elements. It seems identical to the quartz clock crystal. Some common application fields for 595AG000244DG going beyond the ordinary quartz clock crystal are timing devices for airbag control systems and data transmission for car diagnosis systems. It can also be employed as the oscillation signal source for automotive ECU and the frequency source for radio broadcasting stations.

Working Principle

The working mechanism of 595AG000244DG oscillator is based on the principles of electrical oscillation. It combines an integrated circuit (IC) and an external capacitor and resistor to form a two-stage (Stone–Norton) oscillator. A stable low frequency signal is generated at the bottom stage and is amplified at the second stage. The entire oscillator circuit is composed of an active stage and an active filter, and the active filter further includes an integrator circuit.

Without an external crystal, the integrated circuit can generate a stable frequency and low jitter output. The frequency of the oscillation can be controlled by electrically modulated the internal compensation capacitance (COR value) of the ICs. The 595AG000244DG features high stability, low phase noise, low jitter, as well as a wide operating temperature range.

Conclusion

In summary, 595AG000244DG oscillator utilizes an integrated circuit and an external capacitor and resistor to control the frequency. Generally, it can be applied to replace quartz clock crystal and as the frequency source for radio broadcasting stations. Besides its wide operating temperature ranges, it also has excellent stability, low phase noise, and low jitter.
