What chip with 45M crystal oscillator 50

There are many crystal oscillator manufacturers on the market, and the more well-known ones are Renesas Electronics, STMic, Japan Crystal, NDK crystal oscillator, TXC crystal oscillator, etc. Domestic crystal oscillator brands such as Taijing, Whalen, TROQ (Chuangjie) and so on. TROQ is a domestic brand independently founded by Jinhua Chuangjie Electronics, which was founded by Hu Xiangshu and Wu Qunxian, who have more than 50 years of scientific research experience.

Since its establishment, it has more than 20 years of experience in Taiwanese and Japanese first-line crystal oscillator brand foundry, and has also passed AEC-Q vehicle specification certification, reliable quality, 18,000 standard dust-free workshop, and monthly production capacity of 100 million. Welcome to inquire to receive free samples, and at the same time provide you with free fae technical support.

Commonly used 12MHz packages are HC-49S and 3*8mm 2*6mm cylindrical types, as well as HC-49U, DIP8 rectangular and DIP14.

12MHz crystal oscillator is a quartz crystal oscillator that can regularly produce repeated signals, the frequency value is, the signal it produces is usually a sine wave, 12MHz crystal oscillator is an electronic unit whose output frequency is controlled by quartz crystals, and produces 120,000 repeated vibrations per second, crystal oscillator 12MHz is widely used, commonly used in single-chip microcomputer, it can produce 12 machine cycles, play a timing role, but now single-chip microcomputer requires a much faster running speed, Programs can be written with its internal timer.

455 crystal oscillator and 455e crystal oscillator both belong to ceramic crystal oscillator, which is a piezoelectric component, similar to a quartz crystal resonator, but is actually the same product. In the TV remote control, the crystal oscillator is a yellow, square, 2-pin component, model 455e, and the location is generally near the integrated circuit. In the market, some customers will also search for 455k crystal oscillator, so what is the relationship between 455e crystal oscillator and 455k crystal oscillator?

Whether their parameters are the same, here Yangxing Technology will explain to you that under normal circumstances, there will be no 455K crystal oscillator. Because the e of the 455E crystal oscillator is a frequency band between 401 and 509K that represents the ceramic crystal oscillator. Therefore, 455k and 455e are interoperable, or it may be that the names on the market are different.

In various remote controls, the conventional ceramic resonant frequency is 455kHz, because the remote control needs a certain clock signal source to work, which divides, encodes and transmits the clock signal, and then becomes an infrared command signal. A ceramic crystal oscillator is an electronic component encapsulated in a ceramic case that generates a resonant frequency. It plays the role of generating frequency, and has the characteristics of stability and good anti-interference performance.

It is widely used in various electronic products, lower than the frequency accuracy of quartz crystal resonator, but the cost is also lower than that of quartz crystal resonator, it plays an important role in frequency control, and all electronic products involve frequency transmission and reception need resonators.

Whether the crystal oscillator of the remote control is damaged, it can be measured with a digital multimeter with a capacitance measurement file, first use the highest ohm level to measure the resistance to infinity, and then use the lowest capacitance file to measure the capacitance should be about 250p--320p is good, otherwise it is bad.
