TD-37.500MBD-T application field and working principle

The TD-37.500MBD-T is an oscillator designed for precision timing applications. The oscillator’s key features include a frequency range of 37.5 to 44.99MHz, low jitter, power supply current consumption of 7mA maximum and two logic outputs. This crystal oscillator is suitable for a variety of applications such as radio communication systems, telecommunications, professional sound equipment, and medical imaging systems.

The TD-37.500MBD-T features an adjustable frequency range of 37.5MHz to 44.99MHz and an output of two logic outputs available in both LVDS and LVPECL logic levels. The high precision of the crystal oscillator ensures low rate jitter and low phase jitter, while the wide dynamic range provides superior performance in applications with variable input power. The design of the oscillator also enables low power consumption, thus providing excellent efficiency and long battery life in portable applications. Furthermore, the temperature stability of the oscillator is also excellent, as it has been engineered to withstand temperatures ranging from -40°C to +85°C.

The work principle of the oscillator is based on two separate multiplier stages. The first stage multiplies the frequency of the crystal input by multiples of 2 in order to obtain the required frequency. The second stage multiplies the frequency of the amplifier output by multiples of 10 in order to obtain the required frequency. Additionally, the oscillator includes an output stage for providing the required output level which may consist of either a single ended or differential output, depending upon the design of the application. The frequency stability is also maintained by properly adjusting the values of the capacitor and inductor elements used in the design process.

The TD-37.500MBD-T is engineered for standard oscillation and synchronous operations, and it supports multiple clocks. The oscillator is also supplied with a user-adjustable holdover feature which allows users to modify its output frequency in order to accommodate environmental changes. The design of the oscillator also includes built-in protections such as temperature over voltage and over current protections which ensure a stable operation.

Overall, the TD-37.500MBD-T is an excellent oscillator for precision timing applications. Its compact size, low jitter, power efficiency, wide range of logic outputs and excellent temperature and voltage stability make it an ideal choice for radio communication systems, telecommunications, professional sound equipment, and medical imaging systems. The oscillator is also very reliable and user-friendly, making it a cost-effective and efficient choice for precision timing solutions.
