Explore SJK's comprehensive portfolio of quartz crystals, oscillators, and frequency control devices. Engineered for reliability and performance, our components power the technology shaping tomorrow's innovations.

MHz Crystal

The fundamental heartbeat of your circuit. This quartz crystal provides a stable and precise frequency reference for microcontrollers, clocks, and a vast range of electronic devices, ensuring reliable timing at a cost-effective price point.


SMD Crystal

DIP Crystal

Automotive MHz Crystal

Crystal Oscillator

A complete clock source in a ready-to-use package. Combining a crystal and an oscillation circuit, it offers robust performance and simplifies your design by providing a stable square wave clock signal.


SPXO

Automotive XO

Differential XO

Spread Spectrum XO

VCXO

Delivers precision with the ability to fine-tune. This oscillator allows for small frequency adjustments via an applied control voltage, essential for clock synchronization and phase-locked loops (PLLs).


CMOS VCXO

Differential VCXO

TCXO/VC-TCXO

Engineered for stability in varying environments. The TCXO counteracts frequency drift caused by temperature changes, while the VC-TCXO adds voltage control for advanced synchronization needs.


TCXO/VC-TCXO

OCXO

The pinnacle of frequency stability. By maintaining the crystal at a constant high temperature, OCXOs deliver exceptional precision with minimal drift, critical for instrumentation and telecom infrastructure.


 OCXO

32.768KHz Solution

The classic standard for timekeeping. This low-frequency, low-power crystal is the cornerstone of Real-Time Clocks (RTCs) in watches, wearables, and embedded systems, enabling accurate seconds counting.


32.768KHz Crystal

32.768KHz XO

RTC

Your system's perpetual calendar and clock. This integrated module combines a 32.768 kHz crystal, the oscillator circuit, and counter logic to track time, even when main power is disconnected.


RTC

Ceramic Resonator & Filter

A compact and cost-effective alternative for timing and filtering. Ceramic resonators provide a robust clock source, while ceramic filters selectively pass desired frequencies, rejecting noise in RF circuits.


Ceramic Resonator

Ceramic Filter

SAW Device

A specialized component for radio frequency (RF) systems. Surface Acoustic Wave devices act as incredibly precise filters or resonators, enabling clear signal transmission and reception in wireless applications.


SAW Resonator

SAW Filter
