The new wave of EPSON crystal oscillator intelligent electric car market

    In recent years, driven by the trend of intelligent electrification in the automotive industry, crystal oscillators have also experienced rapid growth. At the same time, as crystal oscillators are developing towards miniaturization, high precision, low power consumption, and energy saving, the same requirements have been put forward for electronic components such as crystal oscillators. SMD packaged surface mount crystal oscillators have the characteristics of small size and easy mounting, and have become the mainstream in the market. Epson Electronics believes that in the context of the continuous promotion of intelligent electric vehicles, the stable situation of the domestic intelligent electric vehicle industry will continue to grow in the next few years, which is undoubtedly the breakthrough point in the field of automotive grade crystal oscillators.

    However, the automotive standard crystal oscillator first meets the working temperature range of -40~+125 ℃, and has the characteristics of low power supply voltage, high precision, small jitter, and low power consumption. The 3225 chip crystal oscillator used in automotive systems includes audio, Bluetooth, radar, clock, display screen, etc. 12M crystal oscillators, 16MHz and 26Hz chip mounted crystal oscillators are used in car audio, 32.768K crystal oscillators are used in clocks, and car mounted crystal oscillators are also used for reversing radar. For example, 3225 packaged 16MHz, 26M, and 32M crystal oscillators are commonly used in radar, especially in high-temperature resistance. Crystal oscillators in automotive electronics are best able to operate normally at high and low temperatures. For example, the 3225 volume patch crystal oscillator, which has been determined to have high reliability, is most suitable for use in automotive electronic components.

    Vehicle mounted crystal oscillators can also exhibit stable oscillation characteristics under extremely harsh environmental conditions, with operating temperatures ranging from -40 to+125 ℃. The common 3225 packaged surface mount crystal oscillator and its application scenarios in automobiles include navigation, remote calling, emergency rescue, anti-theft tracking, road rescue, telephone, information and entertainment, downloading applications, autonomous driving, etc. In order to achieve free interaction between human and automotive systems and provide real-time information interaction, payment, transportation, weather and other functions, the dependence of automobiles on automotive grade crystal oscillators will only become stronger and stronger. Overall, the 3225mm volume patch crystal oscillator meets the requirements for normal operation of automobiles under both high and low temperature conditions. The crystal oscillator itself has excellent environmental resistance characteristics such as heat resistance, vibration resistance, and impact resistance, meeting the high-temperature reflow temperature curve requirements for lead-free soldering and complying with the AEC-Q200 standard.
