TB-1.544MDD-T

Oscillators are important components in modern electronic system, especially in the field of communications. TB-1.544MDD-T has been developed to satisfy the needs of such system. This article will discuss its application fields and working principle.

TB-1.544MDD-T is an oscillator based on the Pierce oscillation principle. It presents a simple and neat design in consideration of its wide applications. It is commonly used to generate stable and accurate frequencies in the range of 1.544 MHz. Because of its low cost, simple structure, and low jitter, it can be widely used in communication systems, such as GSM, TDMA, CDMA, and so on.

The signal output by the oscillator contains a combination of the basic wave, its harmonics, and a low-frequency component. Its components are generated through the Pierce oscillator, which is composed of a BJT or FET transistor and a tuned LC circuit with capacitors and inductors. The Pierce oscillator works in saturation-cutoff mode. When Vcc is applied, the BJT or FET transistor is in saturation and conducting current. The current charges the LC circuit and the voltage is excited to a large value. After the transistor changes to the cutoff state, the LC circuit will discharge to the ground. This process produces an oscillating waveform. The frequency of the waveform is determined by the value of the tuning capacitance and inductance.

The TB-1.544MDD-T oscillator is also equipped with an internal reference oscillator, which greatly increases the accuracy of the frequency output. The reference oscillator is composed of an oscillator and a prescaler. It provides a reference signal to the main oscillator to prevent the frequency from drifting. This improves the stability of the output frequency, making it possible to accurately produce the required frequency.

Another important feature of TB-1.544MDD-T is its shape factor. The shape factor is a measure of how well the oscillator is able to reject noise. The shape factor is generally increased as the number of loops in the oscillator’s cycle increases. The TB-1.544MDD-T oscillator has a shape factor of 0.9, which indicates that it has a low noise level.

TB-1.544MDD-T is a useful and cost-effective oscillator widely used in communication systems. It generates stable and accurate frequencies from 1.544 MHz to 200 MHz, and can reject noise with a shape factor of 0.9, making it ideal for many communication applications.
