X1E000341003100 Crystal oscillator leads the new era of automotive equipment

    Most microcontrollers in car navigation systems use external crystal oscillators. In the circuit design of car navigation systems, the size of printed circuit boards is usually small, requiring long time, high efficiency, and stable operation. Therefore, adopting high stability and miniaturized crystal oscillators is of great significance. EPSON Crystal Company has launched a FA-238A factory coded X1E000341003100 crystal oscillator, which is very suitable for application in the design of car navigation systems. FA-238A crystal is a MHz crystal produced by Epson's crystal oscillator factory. It has excellent frequency performance and complies with the AEC-Q200 standard. The packaging size is only 3.2 × 2.5 × 0.7mm, with a working temperature range of -40~125 ℃. It has high stability and low power consumption, making it the best choice for high-precision clocks in car equipment. At present, it is mainly used in car multimedia, car navigation, instruments, remote keys and other on-board devices with high space requirements.

    The FA-238A automotive grade crystal oscillator is a MHz crystal oscillator produced by Epson, which has excellent frequency performance. The output frequency of the FA-238A crystal oscillator is 12MHz~62.4MHz, and the load capacitance is 7pF, providing designers with more flexible choices through appropriate matching circuits. The FA-238A code X1E000341003100 can stabilize the frequency of the crystal with an output frequency tolerance of less than 15ppm~50ppm, and its output signal only contains the fundamental frequency component. In addition, the FA-238A has good temperature adaptability with a frequency temperature characteristic of (-40~85), and the frequency aging rate at room temperature is only+5ppm/year, which can ensure the long service life of the components and is easy to achieve low-power design.

    In order to meet the stability of the output signal and ensure the miniaturization of the design, Epson has designed FA-238A encoding X1E00034100310, which meets the requirements of automotive grade temperature in terms of output stability and low power consumption. The frequency temperature coefficient is -+50x10-6, and the output frequency is less affected by temperature. The maximum crystal aging rate is only+5x106/year. Long service life, meeting the stability requirements of car navigation. Typical applications of FA-238A crystal oscillator: car audio, ECU clock, clock, car navigation system, instrument, remote control access control. The maximum excitation power of FA-238A is 200UW (recommended value is 1-100UW), and the frequency tolerance is (+15 * 10-6~(+50 * 10-6)), which can meet the low-power application requirements of cars. Epson crystal oscillator FA-238A encoding X1E00034100310 meets the requirements of automotive grade temperature in terms of output stability and low power consumption. The output frequency is less affected by temperature, has a long service life, and meets the stability requirements of car navigation. The FA-238A crystal oscillator, when connected to a microcontroller, provides a high-precision, high-frequency clock reference for the microcontroller. The microcontroller can be connected to LCD displays, memory, wireless modules, etc. to complete instrument communication and indication functions. Crystal oscillators require load capacitors and application requirements.
