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.

Solutions to crystal oscillator frequency multiplication interference

Crystal oscillator frequency doubling interference (high-order harmonic radiation) poses a significant challenge in electromagnetic compatibility (EMC) design, typically manifesting as excessive radiation at the 5th and 7th harmonics of the 25MHz fundamental frequency (e.g., 125MHz, 175MHz). This phenomenon arises from the square wave signals emitted by crystal oscillators, which contain abundant harmonic components. When combined with improper PCB layout, these signals can transform into highly efficient radiation antennas.
