High precision temperature compensated crystal oscillators for miniaturization design of unmanned aerial vehicles: TG2016SMN and TG2520SMN. The development of drones can be said to be very rapid, with drones often showing their skills in fields such as security, agriculture, transportation, electricity, and live streaming. The application field of drones is very extensive, with stronger functions and higher performance. Subsequently, becoming more intelligent and miniaturized is also a trend in the development of drones. Generally speaking, reducing the size and weight of drones can help improve their mounting capacity, reduce energy consumption, and extend battery life. So, what can be done to help miniaturize drones? Let's analyze the system of the drone, which includes electronic control components such as motor drive, navigation obstacle avoidance, data transmission module, image transmission module, etc. The operation of these electronic components requires crystal oscillators to provide a stable clock source for the system. Especially in terms of positioning and navigation, data and image transmission, wireless communication requires higher clock requirements, and there are many places where high-precision crystal oscillators are needed, such as WIF!, 2.4GHz or Sub GHz, Bluetooth, GPS, Beidou, 4G, etc., temperature compensated crystal oscillator TCXO is a good choice, but often larger in size. At this point, EPSON's small volume temperature compensated crystal oscillator TCXO can play a role, as shown in the following figure:

EPSON's small volume temperature compensated crystal oscillator TCXO: TG2016SMN and TG2520SMN help unmanned aerial vehicles achieve miniaturization design. The size of TG2016SMN is only 2.0x1.6 x0.7mm, while the size of TG2520SMN is 2.5 x2.0 x0.8mm Although TG2016SMN and TG2520SMN are small in size, they have high accuracy. In the temperature range of -40 ℃ to+85 ℃, the frequency accuracy can reach ± 0.5ppm, and models with ± 2ppm accuracy are available for selection. They provide high-precision clocks for wireless communication, ensuring wireless frequency stability, ensuring reception sensitivity, improving communication reliability and distance, and allowing drones to fly higher and farther. The frequency range is 10MHz to 55MHz, which can provide commonly used frequency points such as 16MHz, 19,2MHz, 24MHz, 25MHz, 38.4MHz for drone wireless communication. The working voltage range is 17V to 3.63V, which can meet 1.8V, 2.8V, and other requirements. Different voltage application requirements for V, 3.0V, 3.3V. At the same time, it has a low working current of about 1.5mA, which can reduce the current consumption of drones, improve battery life, and enhance drone flight time. Small volume packaging is also a future trend for TCXO.
