The role of RTC real-time clock chip

In the fields of the Internet of Things (IoT), industrial control, automotive systems, medical devices, and consumer electronics, accurate, continuous, and lossless real-time data during power outages serves as the foundation for system operation. A Real-Time Clock (RTC) chip is an independent dedicated timing chip responsible for providing stable calendar clocks, power failure endurance, timed interrupts, and high-precision timestamps.

Clock correlation between active crystal oscillators, passive crystal oscillators and MCUs

Passive crystal oscillators and active crystal oscillators are two core solutions for MCU clock systems. Passive crystal oscillators rely on the internal circuitry of the MCU to provide a low-cost, low-power clock supply, making them the preferred choice for general-purpose applications. Active crystal oscillators work independently, offering higher stability and high-frequency characteristics to meet the needs of high-end applications.

Detailed Explanation of Pin Definition of Voltage Controlled Oscillator (VC-OCXO)

The oven-controlled crystal oscillator (OCXO) serves as the core component of high-precision frequency sources. It utilizes high-Q chips with optimized cutting profiles (e.g., SC-cut or AT-cut high-precision types) and minimal packaging stress. Through ultra-precise temperature control in an oven, the oscillator operates at the zero temperature coefficient point, effectively eliminating temperature-induced frequency drift. Widely applied in fields requiring extreme frequency accuracy, such as communications, navigation, and testing.

Temperature-compensated crystal oscillator (TCXO) – providing a highly stable clock for GNSS positioning systems.

In GNSS positioning systems, the frequency stability of reference clocks directly impacts positioning accuracy, startup speed, and system reliability. The Temperature-Corrected Crystal Oscillator (TCXO), serving as the core clock source, is a critical component that ensures stable operation in satellite signal acquisition, tracking, and positioning calculations.
