DSC1121CL2-125.0000

An oscillator is an electronic device that produces an alternating electrical signal at a certain frequency. This signal is then used to perform various electrical tasks. The DSC1121CL2-125.0000 is a type of crystal oscillator, which uses a quartz crystal to control the frequency of the oscillator output. It can be used in a variety of applications such as clock generation, timing, radio frequency generation, and control.

Application Field

The DSC1121CL2-125.0000 is a highly stable crystal oscillator that provides a reliable clock signal. It has a frequency of 125.0000 MHz, making it ideal for applications that require high frequency accuracy such as communications, instrumentation, and data acquisition. It also has a wide operating temperature range, which makes it suitable for use in harsh industrial environments.

The DSC1121CL2-125.0000 is also suitable for use in frequency synthesizers and phase-locked loops. Frequency synthesizers are used to generate multiple frequencies from a single oscillator, and phase-locked loops allow for precise synchronization between multiple oscillators. These applications require precise frequency accuracy, which the DSC1121CL2-125.0000 is able to provide.

Working Principle

The DSC1121CL2-125.0000 is a quartz crystal oscillator that uses an AT cut quartz crystal to control the frequency of its output. The quartz crystal has a natural resonant frequency, and the oscillator is designed to excite this frequency. The crystal is mounted on a holder and is electrically connected to an oscillator circuit. This circuit contains an amplifier and a feedback loop.

The oscillator circuit is designed to maintain a precise frequency by ensuring that the output frequency matches the resonant frequency of the quartz crystal. When the output frequency drifts from the target frequency, a feedback signal is sent to the amplifier, which increases the voltage driving the crystal. This causes the frequency to shift back to the target frequency. This process of frequency control is called “pullability”, and is the key feature that makes quartz crystal oscillators so precise.

Conclusion

The DSC1121CL2-125.0000 is a quartz crystal oscillator that can be used for applications that require a highly accurate timing signal. It is suitable for use in communications, instrumentation, and data acquisition, as well as frequency synthesis and phase-locked loops. It operates by maintaining a precise frequency based on the natural resonant frequency of a quartz crystal, and can be adjusted by the feedback signal generated by the oscillator circuit.
