Oscillators are important components it many electronic circuits and devices, and each type has a unique set of features and specifications that make it suitable for different situations. The ​ASEMB-14.7456​MHz-LC-T oscillator is one such example, and its application field and working principle are outlined below.

Application Field

Designed for use in consumer electronics, commercial, industrial, and medical applications, the ASEMB-14.7456 MHz-LC-T oscillator is a high-precision, low-cost solution for timing and frequency control. Its compact size allows it to be used in a range of electronic products such as TVs, DVD players, alarm systems, and communications systems.

The oscillator features a low voltage consumption of 1.2V, eliminating the need for an external power supply, and a wide operating temperature range of -40°C to 85°C. This makes it ideal for applications that require ultra-low power consumption, such as wearable electronics and IoT devices.

In addition, the oscillator is RoHS compliant and offers a stability rate of ± 30ppm over a frequency range of ±1MHz to ±5MHz. This stability rate ensures that timing and frequency signals remain consistent, protecting any connected circuitry from unwanted frequency drift.

Working Principle

The ASEMB-14.7456 MHz-LC-T oscillator is a LCD-T-type crystal oscillator, comprised of an amplifier, quartz crystal unit and a feedback loop. The frequency of the LC oscillator is determined by the values of the inductor and capacitor components. The crystal in the quartz crystal unit acts as an impedance, which influences the LC resonance frequency.

When a voltage is applied to the terminals of the oscillator, an alternating capacitance is created between the oscillator\'s two plates. This creates an oscillating current between the plates, which oscillates at a frequency determined by the oscillator\'s inductor and capacitor values. The quartz crystal, however, acts as a filter that suppresses unwanted frequencies, allowing only the desired frequency to pass.

The output of the oscillator is then fed back into the input of the amplifier, which in turn amplifies the signal. This amplified output is then fed back to the quartz crystal unit, where it is filtered and fed back to the amplifier. This process continues indefinitely, creating a continuous output frequency of 14.7456MHz.

Conclusion

The ASEMB-14.7456 MHz-LC-T is an excellent choice for low voltage, low-costfrequency and timing control applications in consumer electronics, commercial, industrial, medical and other applications. Its small size, low voltage consumption, high precision and wide temperature range make it ideal for use in devices such as wearables and IoT products. The working principle of the LC-T oscillator is based on the interaction between the oscillator\'s inductor and capacitor elements, the quartz crystal filter, and an amplifier, all which work together to provide a stable 14.7456MHz output.
