TD-25.000MBD-T Datasheet/PDFOscillators: TD-25.000MBD-T Application Field and Working Principle
The TD-25.000MBD-T oscillator is a 25.000 MHz voltage controlled temperature compensated crystal oscillator (VCTCXO) from Sunny Group Co, Ltd. It is a miniature SMD type oscillator and has low noise and low jitter performance. This oscillator is suitable for a wide range of applications, such as cellular base stations, HDTV, broadcast equipment, GPS systems, and industrial automation.
The working principle of TD-25.000MBD-T oscillator is based on the piezoelectric effect. Piezoelectricity is produced when piezoelectric material is placed between two metal plates and an electric field is applied to the material. The electric field causes the material to vibrate and generate an oscillating electric signal. The frequency of the signal is proportional to the applied electric field. This type of oscillator is called a voltage controlled temperature compensated crystal oscillator (VCTCXO).
The main feature of TD-25.000MBD-T oscillator is its temperature compensation. This ability to maintain the desired frequency output over a wide range of temperature variations is achieved by using a special temperature compensated crystal inside the oscillator. The temperature compensation is obtained by utilizing an analog temperature sensing circuit, which adjusts the frequency output of the oscillator in order to counter the effect of temperature change.
The TD-25.000MBD-T oscillator can operate over a wide supply voltage range (2.8V-3.3V) and a wide temperature range (–40°C to +85°C). This allows it to work reliably in harsh environments, and ensures its durability and reliability in the field.
The TD-25.000MBD-T oscillator also features low phase noise and jitter performance, which makes it ideal for high-precision applications such as HDTV system and GPS systems. This makes it the perfect choice for designers looking for a reliable and accurate oscillator in their applications.
In conclusion, the TD-25.000MBD-T oscillator is a highly reliable and precise voltage controlled temperature compensated crystal oscillator which is suitable for a wide range of applications. Its low noise and jitter performance makes it ideal for high-precision applications, and its wide temperature and supply voltage ranges make it highly reliable for operation in harsh environment.
