Taking CM309E7680000BBIT as an example, crystals, which can be classified as piezoelectric components, are widely used in electronic and communication applications. CM309E7680000BBIT is a typical quartz crystal that has been designed specifically for use in television and radio broadcasting. The selection of CM309E7680000BBIT is based on the frequency of operation and other performance characteristics required for the application.

The application field of CM309E7680000BBIT mainly covers television and radio broadcasting. CM309E7680000BBIT crystals can provide a stable clock signal at a fixed frequency, which is extremely important in transmitting, receiving, and the process of signal processing. In this way, a perfectly stable signal can be transmitted and received, which has a significant role in maintaining a clear video image, apart from enhancing the efficiency of data transmission and reception.

The working principle of CM309E7680000BBIT can be described as follows: it consists of several quartz plates that have been permanently fixed together in a specific structure. When current passes through the quartz, it induces a voltage, thus creating a crystal oscillator. The frequency of this oscillator will be determined by the quartz plates’ physical structure. Usually, CM309E7680000BBIT crystals can generate a frequency of 768 MHz, which is suitable for television and radio broadcasting.

In addition to the frequency of operation, the performance characteristics of CM309E7680000BBIT crystals includes stability, temperature coefficients, and power consumption. To further guarantee a stable signal transmission and reception, the frequency stability should not be more than 3 x 10-7 over an operating temperature range of -20 to +70°C. In other words, the frequency tolerance must be held to within this stated range. Moreover, the CM309E7680000BBIT crystals should have an operating temperature range of -20 to +70°C with a temperature coefficient of not more than 5 x 10-7/ °C. Lastly, the power consumption of CM309E7680000BBIT should not exceed 2.5 mW at 25°C and 850 mW at 85°C.

Overall, by precisely engineering the quartz plates, CM309E7680000BBIT crystals can provide a stable clock signal at 768 MHz. This has made it an ideal choice for television and radio broadcasting, dramatically increasing the efficiency of signal transmissions and receptions.
