403C11A40M00000 application field and working principle

403C11A40M00000 is a crystal oscillator conforming to the ITU-T G.787 and G.958 standards. It is a type of transistor-based delay line, which can modify the load capacitance of the device in order to achieve the desired frequency of oscillation. This device is used in a wide variety of telecommunications applications, ranging from cordless phones to cellular networks.

Design

The 403C11A40M00000 crystal oscillator consists of two metal plates, known as electrodes, and two small metal connections. These two metal connections are insulated and placed at a very small gap between them, such that when a current is applied, the two electrodes will form an oscillator. The current passing between the two electrodes is proportional to the oscillation frequency, and the load capacitance is adjustable.The 403C11A40M00000 can be used as a base transceiver station (BTS), digital cross-connect (DCX), or backbone transmission node (BTN), among other things. Since it is a delay line based oscillator, it is ideal for digital transmissions in line-of-sight communication, where relatively low-noise signals are required.

Application

The 403C11A40M00000 crystal oscillator has a wide range of applications. It is used in a variety of telecommunications systems, such as cordless phones, cellular networks, and trunked radio systems. It is also used in GPS systems, satellite modems, sonar systems, and radio frequency automotive systems. Additionally, it is used in optical systems, such as trans-receivers, routers, and cable modems.

Working Principle

The working principle of the 403C11A40M00000 crystal oscillator is the same as any other transistor-based delay line. When a current is applied to the two electrodes, they form an oscillator that produces a signal that is relatively low-noise. The oscillation frequency is dependent on the load capacitance, which can be adjusted as needed.The delay line is made up of two parts: a cascade of transistors and an RC network. The transistors amplify the current passing between the two electrodes, and the RC network provides the capacitance value required to achieve the desired frequency of oscillation.

Advantages

The 403C11A40M00000 crystal oscillator is a very reliable and cost-effective device. Its main advantage is its low-noise operation. This makes it ideal for line-of-sight communication systems, where high-quality signals are required. Additionally, the device is relatively small and easy to install.

Disadvantages

One of the main drawbacks of the 403C11A40M00000 crystal oscillator is that it requires precise adjustments in order to achieve the desired frequency of oscillation. If the capacitance value is not set correctly, the oscillator will not produce the desired signal. Additionally, the device is sensitive to temperature changes and power supplies, which can cause it to produce different frequencies than the desired one.
