Crystal 32.768K promote high-tech development road |

Updated from the intelligent mobile phone, smart watches to continue to improve, and then continue to change the new computer, 32.768K crystal, are essential, whether it is driving recorder, or other electronic products, almost all cannot do without crystal 32.768K, therefore, the next patch crystal oscillator 32.768K will promote the development of high-tech road.
The use of high-tech products have the surrounding crystal figure
Mobile phone, computer, circuit board inside the iPad almost in every crystal, and a board above at least two above crystal. Today, we do not discuss the crystal in its internal role. First of all, foreign and domestic crystal differences too, such as the domestic market 32.768K crystal, 20ppm common cylindrical crystal, the price may be around $0.18, while imports of crystal, such as the well-known Japanese brand EPSON crystal, KDS crystal and other basic price in 0.36 yuan. And the accuracy of the value of the market is a common kind of. Why should it specially stressed that the precision, a crystal precision value, is also his error size determines the performance of the crystal itself. From another point of view, the accuracy of crystal was higher, so its quality is better, here to talk about the crystal precision value can produce the profound influence.
The crystal precision, why we can call the error size. 32.768K crystal to the circuit board all the role, is used for time display, time is the precise value of the crystal precision value decision. While 32.768K only crystal quartz crystal, quartz crystal because of higher accuracy than the ceramic crystal. How time error is calculated. Ppm is a unit of crystal precision, on behalf of a millionth. If we choose the crystal is 20ppm, the time error that day should be 24*60*60*20*0.000001=1.728 seconds. A day of time error is out, a day a second time error, may we perceive, but a long time, the time error naturally very obvious. If you need more precise time point, should choose high precision quartz crystal. Relatively speaking, crystal welding is more simple. But the cost will be much higher than the crystal plug.
Why crystal promoted the development of high-tech? For example, 360 children watch the 3 and 2 generation difference, HUAWEI and millet 5 mate8, or apple mobile phone and mobile phone, crystal type with internal differences of these electronic products are large, so the performance and the quality of their difference is greater. The 32.768K crystal differentiation, also led to the quality of these products is different, therefore, the crystal progress, which means the progress of high-tech products.
