Epson TG-3541CE temperature compensated crystal oscillator high-precision clock solution

In the core components of electronic devices, crystal oscillators are like hearts, providing stable and accurate clock signals for the system. Their performance directly affects the overall performance of the device. The Epson TG-3541CE series temperature compensated crystal oscillator, with its excellent characteristics at a frequency of 32.768kHz, has demonstrated unparalleled advantages in many fields and has become an ideal solution for high-precision timing and harsh environments.

Epson TG-3541CE is a temperature compensated crystal oscillator (TCXO) designed specifically for high-precision timing and harsh environments. With an output frequency of 32.768kHz as the core and advanced digital temperature compensation technology (DTCXO), it has demonstrated outstanding performance in industrial control, automotive electronics, and the Internet of Things. Due to its built-in temperature compensation function, the temperature stability of the output frequency is as high as 3.4ppm (Ta=-40 ℃~85 ℃). Due to the inclusion of factors such as temperature and voltage that affect frequency deviation, the actual timing accuracy is equivalent to a 9-second deviation per month.

This series of crystal oscillators performs excellently in terms of electrical parameters. It adopts standard CMOS output, effectively enhancing the anti-interference ability of signals, making signal transmission stable and reliable in complex electromagnetic environments. Its working voltage range is 1.5V to 5.5V, which can flexibly adapt to various electronic system designs, reducing the complexity and cost of system design. Under no-load conditions, the maximum current loss is only 3 μ A (typical value is 1 μ A), and the maximum shutdown current is 1.5 μ A (at VCC=3.0V), exhibiting extremely low power consumption characteristics and helping to extend the battery life of the device, especially suitable for portable devices and IoT terminals that are sensitive to power consumption. The maximum load capacitance is 30pF, and the design accuracy is extremely high. The XA crystal oscillator can control the frequency tolerance within ± 3.4ppm in the temperature range of -40 ℃ to+85 ℃, and the XB crystal oscillator can control the frequency tolerance within ± 5ppm in the same temperature range, ensuring stable and accurate frequency output and laying a solid foundation for the long-term stable operation of the equipment.

The Epson TG-3541CE series 32.768kHz temperature compensated crystal oscillator has shown great potential in many fields such as industrial control, automotive electronics, communication systems, and the Internet of Things due to its high-precision frequency output, excellent temperature stability, superior electrical performance, fast start-up, and low-frequency aging characteristics. For users who pursue high performance, high reliability, and long service life of their devices, the Epson TG-3541CE series is undoubtedly an ideal choice for achieving excellent product design, helping various industries steadily advance on the path of technological innovation and product upgrading.
