  • Crystal size change trend and advantages
    Crystal size change trend and advantages
    • Nov 13, 2019

    All knows that the 32.768KHz crystal oscillator must be called the crystal in the clock. In recent years, the entire crystal industry has also been changing with the changes in market demand. The most obvious is the change in crystal size. As we can see, the trend of crystal volume changes in recent years. It can be seen from the figure that the mainstream of the market today is the ultra-small ultra-thin patch crystal. Small patch quartz crystal oscillator with thin surface-mount quartz crystal resonator. It is especially suitable for market areas with miniaturization requirements. The crystal oscillator itself is ultra-small, thin and light, and the crystal has excellent environmental resistance, such as resistance. Thermal and impact resistance, in the field of office automation, home appliance related electrical appliances and short-range wireless communication such as Bluetooth and Wireless LAN, can exert excellent electrical characteristics and meet the reflow temperature curve requirements of lead-free soldering. General civilian products use ordinary crystal resonators. Because some high-end smart products have stricter requirements on crystal oscillators, oscillators are used. Advantages of the oscillator: Fast start, low voltage operation, low level drive and low current consumption have become a trend, and the supply voltage is typically 3.3V. Many TCXO and VCXO products have current losses of no more than 2 mA. The rapid start-up technology of quartz crystal oscillators has also made breakthroughs.

  • Resonator and Ceramic crystal function
    Resonator and Ceramic crystal function
    • Aug 08, 2019

    Resonator functions: The resonator acts as a clock in the circuit, providing a pulse signal of a specific frequency for the entire circuit, so that each component in the circuit can complete the commands rhythmically under this signal. Because the work of any computer or micro-controller is in accordance with a certain beat, the beat is the clock signal, which is generated by the resonator. The resonator is mainly used in the CPU circuit with signal processing capability, especially in the single-chip microcomputer. 1. Computer CPU: dealing with complex and huge data, Mainly used for core processors of computers and servers. 2. Single-chip CPU: miniaturized, can handle simple machine assembly language, Complete simple machine instructions. Mainly used in the signal processing board of each circuit. For example: mobile phone circuit board, circuit board of car igniter, remote control,                        Cameras, DVDs, etc. are required in the board of the micro-controller. The client selects the resonator requirements: The type of the microcontroller is different, and the required operating frequency is different, so the resonator used to provide the specific frequency is different. Ø For example, USB1.0 has a small transmission speed, a low data volume, and a relatively small required frequency. Ø USB2.0 has a large transmission speed, a high amount of data, and a relatively large frequency. For the specific frequency requirements of the resonator, the client determines the resonator of the desired frequency depending on the type of micro-controller used. Sometimes more than two frequency signals are required in a single board, so more than two resonators must be assembled to provide the pulse signals required by the circuit. The frequency of our main resonators: 8MHz, 12MHz, 16MHz, 16.93MHz, 20MHz,25MHz, 40MHz, 48MHz, 50MHz and other frequencies. Difference between quartz crystal resonator and ceramic resonator Material difference: ² Quartz crystal resonator: It is processed by cutting a natural piezoelectric material into a desired shape. ² Ceramic Vibrator: A powder with a piezoelectric effect is artificially prepared, and then the powder is compression molded and sintered to make the desired product size. Since the quartz crystal resonator is cut from a natural material, the axial direction, size and thickness of the cut directly affect the frequency of the quartz crystal resonator, so the frequency of the quartz crystal resonator is affected by the material size, thickness, and shape. The actual processed quartz crystal resonators tend to be large in size and are well suited for highly integrated, high-density surface mount circuit designs. The ceramic resonator can be modified by the PZT (piezoelectric ceramic material) formulation, so that the frequency of the product is not limited by the material size, and...
