Crystals and the 406C35D48M00000 Application Field and Working Principle

Crystals are tiny pieces of quartz or other materials, usually cut in the form of a disc or cylinder, which vibrate at a specific frequency when excited by electrical energy. As such, they are widely used in radio, seismic and navigation equipment, quartz clocks, and a variety of other electronic devices. In recent years, the development of advanced semiconductor technology has led to the increased use of very thin slices of silicon and germanium called on-chip crystals (OCXs). The development of OCXs allows for much greater control over the frequency of the oscillator, higher stability and lower power requirements.The 406C35D48M00000 is an OCX that is especially well-suited for use in the automotive industry. It is a small, low-profile device that is resistant to wide fluctuations in temperature that occur inside vehicles. This allows the device to work reliably in even the most extreme climates. Furthermore, it has a wide operating temperature range of -40°C to +85°C and is rated for operation at frequencies up to 40MHz. The 406C35D48M00000 uses a SMOS (Silicon-MOSFET Oscillator) process to create a reliable oscillator with a minimum of active devices. A MOSFET is a type of insulated-gate field-effect transistor that can be used to amplify signals in electronic circuits. The MOSFETs in the 406C35D48M00000 are tuned to oscillate at a pre-determined frequency, usually selected via an on-chip trimming mechanism. Intrinsic capacitor (or metal bridges) are then used to set the desired frequency.The device also features a high-Q (quality factor) oscillator design. A Q factor is an important metric in electronics engineering and is used to measure the sharpness of a resonant peak in an acoustic or electrical system. The higher the Q, the higher the peak, which makes the oscillator more accurate and stable. The 406C35D48M00000 has a Q factor of approximately 4, which helps ensure its accuracy and stability.The wide range of operating temperature and stability of the 406C35D48M00000 make it an ideal choice for a wide range of automotive applications. It can be used for engine control systems, power sharing applications, and various types of electronic control systems in the automotive industry. It is also suitable for applications such as frequency synthesizers and local oscillators used in radio and network communication systems.In conclusion, the 406C35D48M00000 is an advanced, low-profile OCX specifically designed for automotive applications. Its wide operating temperature range, reliable oscillator design and exceptional stability make it an excellent choice for automotive systems and other applications requiring precise frequency control.
