Crystals - 405I35B14M40000 Application Field and Working Principle

Crystals are a vital component that is used in many electrical and electronic devices in order to control frequency, timing, and/or phase operations. They are frequently used in oscillators, filters, amplifiers, clocks, and micro-controller circuits. One such crystal, the 405I35B14M40000, is often used in telecom and military applications, requiring precise timing and accurate frequency control. In this article, we will discuss the application field of the 405I35B14M40000 crystal, as well as its working principle.The 405I35B14M40000 is an oven-controlled crystal oscillator (OCXO) specifically designed for telecom and military applications. It is an SMD type crystal so it is designed to maximize space efficiency. The device operates at a 10.118 MHz frequency with an accuracy of ±20 ppm. The frequency stability of the oscillator is 0.06 ppm over the -35°C to +85°C temperature range and is rated for a maximum operating temperature of 105°C. It also has an exceptionally low phase noise of -120 dBc/Hz at a 1 kHz offset, which makes it ideal for applications where timing stability and accuracy are key.In a telecom or military application, the 405I35B14M40000 crystal is often used in a frequency synthesizer circuit, which produces a single frequency of oscillation at the required frequency. This crystal oscillator generates a stable output frequency to drive the frequency synthesizer, which then produces the desired output frequency. The device is also effective in very low-noise, high-speed clock applications. It provides an accurate, stable reference signal for tracking, controlling, and maintaining the output frequency of the circuit. As for the working principle of the 405I35B14M40000 crystal, it basically functions in the same way as any other crystal oscillator. It uses the piezoelectric effect, which occurs when two opposite electric fields are applied to a piezoelectric material, in order to oscillate at a precise frequency. The 405I35B14M40000 is constructed from two pieces of quartz, which form limiters for the electric field. When a voltage is applied, it creates a mechanical stress inside the crystal, which causes the crystal to vibrate. The frequency of the oscillations is determined by the size and shape of the crystal, as well as the applied voltage and capacitance, and is determined by the series resonance circuit that typically consists of an inductor and capacitor. This series resonance circuit is used to determine the frequency of oscillation. The resonant frequency of this crystal oscillator is 10.118 MHz, with a maximum frequency variation of ±20 ppm. The output of the oscillator is filtered and amplified by a voltage controlled amplifier, after which it is used as a timing reference in the referenced system.In conclusion, the 405I35B14M40000 crystal is an oven-controlled crystal oscillator that is specifically designed for telecom and military applications. It operates at a precise frequency of 10.118 MHz, with a maximum frequency variation of ±20 ppm. It has an exceptionally low phase noise of -120 dBc/Hz at a 1 kHz offset and its frequency stability is 0.06 ppm over the -35°C to +85°C temperature range. As for its working principle, it relies on the piezoelectric effect in order to oscillate at its precise frequency, which is determined by the size and shape of the crystal, as well as the applied voltage and capacitance. The output of the oscillator is then filtered and amplified by a voltage controlled amplifier.
