Oscillators: High-Precision Crystal Oscillator Lineup

Oscillators

【MHz Crystal Oscillators】 By integrating a precision resonator and an optimized oscillator IC into a single ultra-compact package, these oscillators eliminate the need for complex analog tuning in high-speed digital designs. The precisely matched internal circuit prevents oscillation instability, circuit mismatches, and noise issues during PCB implementation. Minimizing development burdens, they instantly provide reliable, low-phase-noise clock signals, making them ideal for applications ranging from communication modules to industrial equipment.

【kHz Crystal Oscillators】For 32.768 kHz timing, these oscillators completely isolate the circuit from external noise and PCB leakage currents. Unlike traditional kHz products, they employ a unique non-tuning-fork structure to achieve exceptionally high frequency accuracy. The built-in optimized circuit frees engineers from delicate layout constraints. Utilizing ultra-low-power IC technology, they instantly output clean, precise clock signals upon power-up, providing highly reliable timekeeping for battery-operated systems like smart meters and IoT devices.
