Principle and function of single-chip crystal oscillator circuit

Active crystal oscillator external circuit The usual usage of active crystal oscillator: one pin is suspended, two pins are grounded, three pins are connected to output, and four pins are connected to voltage. Active crystal oscillator does not require the internal oscillator of the MCU, and the connection method is relatively simple.

Working principle of temperature compensated crystal oscillator

Temperature Compensated Crystal Oscillator (TCXO) is a crystal oscillator that improves frequency stability through temperature compensation technology. Its core goal is to offset the crystal resonant frequency drift caused by ambient temperature changes and make the output frequency more stable.

With competition from AI giants such as Deepseek, the annual growth rate of optical transceiver modules is as high as 56.5%

With the trend of miniaturization of electronic products, the package types of optical modules are getting smaller and smaller, and the designs are becoming more and more sophisticated. In order to save PCB space, small-size packages such as 3225/2520 are preferred in crystal oscillator selection, which not only meet the requirements of high speed and low jitter, but also provide a variety of package sizes to meet the design requirements of different optical modules.

The perfect partner for high-precision time management: Co-design of YSN8563 RTC and 32.768kHz crystal oscillator

A real-time clock (RTC) is a dedicated integrated circuit that provides an accurate time reference. The 32.768kHz crystal oscillator is the most commonly used clock source in RTC due to its convenience of binary frequency division, ensuring that RTC can provide a reliable and accurate time reference in various application scenarios.

What happens if two crystal oscillators of different frequencies are placed close together

The oscillation of a crystal is essentially a mechanical vibration (at the piezoelectric crystal level). When two crystals are placed close together, their mechanical vibrations may affect each other. The vibration of one crystal may be transmitted to the other crystal through a medium such as a circuit board or a casing, thereby changing the vibration characteristics of the other crystal.
