TSX-3225 crystal oscillator suitable for intelligent sweeping robots

Intelligent scanning robots are developing towards higher intelligence. They can perform reasonable cleaning according to household layout. The mainstream design scheme is achieved by high-performance microcontrollers and gyroscopes. As the core of the operating processor, the main control microcontroller is the microcontroller. In order to achieve faster and more accurate control of each instruction, a high-precision 25MHz passive crystal with low-temperature drift characteristics is generally needed to match the design of the microcontroller. In response to the above design requirements, EPSON Crystal Oscillator's TSX-3225 series X1E000021075100 imported crystal oscillator has a rated frequency of 25MHz, a load capacity of 10pF, an accuracy of ± 10ppm at room temperature of 25 ℃, and a temperature drift of+1 at -40 ℃~85 ℃. 8ppm, working temperature range -40 ℃~85 ℃, meeting high-precision and low-temperature drift characteristics.

In addition, this TSX-3225 series 25MHz passive Epson crystal oscillator has high precision and adopts a 3225 small-sized package, which can greatly save PCB board space and is conducive to product miniaturization design. To ensure the consistency of communication frequency between MCU and acquisition unit, execution unit, and achieve fast frequency capture, synchronization, and data communication, higher precision products are required. It is recommended to use+10ppm (which is the highest precision of ordinary crystal oscillators). In the case of low-temperature drift, it ensures that the sweeping robot is not affected by the environment of the north and south regions, and can establish stable connections and achieve networking. The lower the value, the better. It is recommended to choose within+20ppm.

The TSX-3225 crystal oscillator is 16MHz~48MHz, with a frequency deviation stability of 10 ppm. The frequency deviation during operation is relatively low, ensuring more accurate signal acquisition and program operation of MCU and CPU. In addition, the long-term operating frequency stability of the 25MHz TSX-3225 crystal is better than+1ppm, much higher than the+5ppm of the ordinary reference clock crystal. It can work stably and reliably on the main board of the sweeping robot for a long time. The TSX-3225 crystal oscillator has a driving power of 200uWmax and oscillation mode is fundamental frequency.
