Oscillators

TC-74.250MDD-T Oscillator is developed by MITSUBISHI Electric Corporation and widely used in various kinds of application fields. It provides stable and precision signal frequency with the high quality crystal element. This oscillator has been widely used in communications, computers, consumer electronics, medical equipment, and automotive electronics. Its features and working principles are discussed in this article.The TC-74.250MDD-T Oscillator consists of a quartz crystal, a transformer and a resonant circuit in which all of these components are preset. The quartz crystal is manufactured at high temperature and is quenched to make sure it is exact and behave as a mechanical resonator. The quartz crystal allows the oscillator to produce a high-precision, stable frequency. It works on the principle of the quartz crystal vibrating at a resonant frequency,when an electric current is applied to the crystal. The frequency of the output signal is determined by the size and shape of the quartz crystal. The transformer converts the low power oscillating signal into a higher power. The signal generated by the crystal is then amplified and filtered by the transformer. The transformer also shapes the signal to create a symmetrical sine wave that is suitable for digital circuits. The resonant circuit works together with the quartz crystal and the transformer. It helps to eliminate noise and prevents it from interfering with the signal.The TC-74.250MDD-T Oscillator can provide an accurate and stable signal frequency at a wide variety of frequencies ranging from 4 MHz to 16 MHz. The oscillator has a low profile size with a maximum height of only 0.4mm making it suitable for use in applications with tight spacing requirements. It has a operational temperature range of -40℃ to +85℃, and an operating voltage from 3.3V to 5.5V.The oscillator comes with built-in overtemperature protection which allows the device to protect the system in case of over-temperature conditions. The oscillator also has a very low phase noise, allowing it to generate signals with very low levels of noise.Due to its high performance and reliability, the TC-74.250MDD-T Oscillator is suitable for a wide range of applications including communications, computers, consumer electronics, medical equipment, and automotive electronics. It is most commonly used in applications where precise clock signals are required, such as in frequency synthesizers, RFID systems, wireless communication systems, and Ethernet based data communication systems. The oscillator is also used in applications such as frequency synthesizers, clock filter circuits, and automotive electronics.In summary, the TC-74.250MDD-T Oscillator is a reliable and high performance oscillator that delivers stable and accurate signal frequency. Its small size and low power consumption make it suitable for space critical applications and helps to reduce the system cost. It has a wide range of operating frequency and low phase noise which allows it to generate precise clock signals. Furthermore, it is designed with built-in over-temperature protection, making it safe and reliable for various applications.
