Epson TG2520SMN 19.2MHz high-precision temperature compensated crystal oscillator assisted panoramic motion camera GPS high stability design

In today's booming era of panoramic motion cameras, it provides unprecedented possibilities for users to capture exciting moments and record adventure journeys. The accuracy and stability of GPS function determine whether the camera can accurately locate the shooting location and record the movement trajectory. To ensure that the GPS positioning function of the panoramic motion camera meets the characteristics of high precision, high stability, and high resistance to temperature effects, the GPS main control MCU generally requires an external high-precision temperature compensated active crystal oscillator design, and the rated frequency is related to the selection of the main control MCU chip. The Epson TG2520SMN crystal oscillator, with its stunning ± 0.5ppm accuracy, has become the core cornerstone of this precise positioning.

This crystal oscillator, with its excellent accuracy, ensures that the camera can accurately lock the satellite position and calculate its latitude and longitude information when receiving GPS signals. The TG2520SMN crystal oscillator can stably output accurate clock signals, providing a reliable time reference for the GPS module, enabling the panoramic motion camera to accurately mark the geographical location of every shooting moment, allowing every journey to be perfectly reproduced on the map.

Epson TG2520SMN is a high-precision TCXO temperature compensated crystal oscillator with a typical output frequency of 19.2MHz. It is packaged in a small 2520 size and has a power supply voltage range of 2.66-3.465V. The accuracy reaches ± 0.5ppm at room temperature of 25 ± 2 ℃, and the working temperature range is -40 ℃~85 ℃. The relevant characteristic parameters are shown in Figure 1.
