The core electronic component of the CPU is the Z crystal oscillator and the Z crystal oscillator.

The core electronic component of the CPU is the Z crystal oscillator and the Z crystal oscillator.

CPU is one of the main devices of electronic computers and the core accessory of computers. the main function is to explain computer commands and process data in computer software. someone will ask, do you know what is in the CPU? I think everyone will talk about silicon crystals, a highly integrated semiconductor material, but no one has mentioned it.Z Crystal OscillatorIt can be seen that in the face of high-tech technology, the Z crystal oscillator is very small (although the crystal oscillator itself is very small). It may be slowly forgotten.
Crystal Oscillator nameZ Crystal OscillatorProvides the basic clock signal for the system. The crystal oscillator is usually used in combination with the Phase-Locked Loop Circuit to provide the clock frequency required by the system. A crystal converted from electrical energy and mechanical energy operates at resonance to provide stable and accurate single-frequency oscillation. under normal operating conditions, the absolute accuracy of the ordinary crystal oscillator frequency can reach 50%, and the advanced accuracy is higher. some crystal oscillator can adjust the frequency from the applied voltage within a certain range.Voltage Controlled Oscillator(VCO ).
A voltage controlled oscillator is an oscillating circuit (VCO) in which the output frequency corresponds to the input control voltage. The frequency is the oscillator VCO of the input signal voltage function, the operating status of the oscillator or the component parameters of the oscillator circuit are controlled by the input control voltage to form a voltage controlled oscillator. an important module of a wireless transceiver. It not only provides stable local vibration signals for the transceiver, but also generates clock signals required by the entire circuit by multiplier. its Phase Noise, adjustment range, and adjustment sensitivity have a great impact on the performance of the wireless transceiver.
A crystal voltage controlled oscillator can be formed by concatenating a variable diode and a Z crystal in a steady-frequency oscillator. In order to expand the frequency modulation range,Z Crystal ResonatorWhich can be used for AT cutting and obtaining its base frequencySMD Crystal OscillatorThe system can also use a network for changing the frequency modulation range. In the microwave band, the reflected Speed Control Oscillator that controls the frequency with the reflected pole voltage and the controlled frequency with the anode voltage also belongControlled Crystal OscillatorThe Application of voltage controlled oscillator is very wide, and integration is an important development direction.
When we walk into the bus station, railway station, airport, or even a large supermarket, we will see a "guard" standing at the door, there will be red lights and alarms when you bring valuables or dangerous items into the body. everything cannot escape from its eyes. It is like Sun Wukong. At a glance, you can recognize the demon or the ghost. "Guard" is composedActive Crystal Oscillator3.5-M sine wave is generated, and the frequency divider is about K sine wave. After the power of the transistor and the coil is amplified, the large coil of the input door board is used for electromagnetic wave emission, and the internal coil receives the sine wave respectively, after receiving, the received signal is compared with the benchmark signal. after the changes are detected, the output level of the acquisition card is changed. The CPU scans the data of 6 Location acquisition cards within 300 milliseconds, judges the metal detection location, and outputs the display.
