With the rapid development of smart electronic products in China, some common electronic products such as wireless Bluetooth headsets and wearable smart visual watches have gradually become the mainstream solutions for today's smart electronic products. These smart electronic product motherboards require more and more crystal oscillators . Just like 2.5G modules, a 40MHz passive crystal oscillator is commonly used on this 2.5G module motherboard. This 2.5G module crystal oscillator has an ultra-small package and High-precision characteristics are very suitable for wireless Bluetooth modules. Choosing a suitable 2.5G module crystal oscillator has higher requirements for frequency accuracy, stability and volume. Therefore, based on these requirements, Jiaco Crystal Electronics recommends a commonly used in Q24FA20H0009700 Epson crystal oscillator with 2.5G module .
Q24FA20H0009700 crystal oscillator has passed ISO14001 international environmental standard certification, and its working temperature has an industrial temperature of -40~85℃, which enables the product to work normally in the harsh environment of hot and cold electronic products. The frequency tolerance (standard) of FA-20H is ± 30x10-6; Therefore, in 2.5G module applications, it can ensure high output frequency accuracy, thereby outputting more accurate signals. In addition, in terms of power consumption, the maximum excitation power of FA-20H is 200μW, which is enough to meet the low power consumption of 2.5G modules Requirements.
Epson's Q24FA20H0009700 crystal oscillator has a load capacitance of 10PF and an accuracy of 10PPM. It has very high stability and is very suitable for the design of smart wearable devices that are sensitive to the design area. The FA-20H crystal oscillator has the characteristics of small size, high precision, and low power consumption. Excellent heat resistance and environmental resistance characteristics make it the best choice for smart wearable device clocks. In addition, the FA-20H crystal metal case package enables the product to exhibit better impact resistance than the ceramic resonator case during packaging, greatly improving Improve the environmental adaptability and fall resistance of smart wearable devices.
