At Xtalong Electronics, we don’t just manufacture oscillators; we engineer precision. As a premier provider of frequency control components, we specialize in OCXO (Oven-Controlled Crystal Oscillators), TCXO, and VCXO solutions. Our mission is to provide global industries with high-performance timing references that push the boundaries of physics.

We are recognized for our industry-leading technical breakthroughs, including:

Ultra-Low Phase Noise: Achieving -168dBc/Hz @ 1kHz offset for 100MHz OCXOs, ideal for high-end radar and satellite communications.

Extreme Stability: Our Double Oven (DOCXO) 10MHz oscillators reach an elite frequency stability of 0.1ppb (parts per billion), ensuring mission-critical precision.

Bridging the Market Gap

In the early stages of our journey, we identified a critical frustration among RF engineers and procurement specialists: the inability to find suppliers willing to handle rare frequencies, low-volume orders, or discontinued components.

Traditional manufacturers often prioritize mass production, leaving specialized projects in a bind. We built our company to fill this void. Whether you need a unique frequency for a legacy system or a small batch of high-precision prototypes, we offer the flexibility that standard channels cannot.

Why Engineering Teams Choose Us？

Custom Frequency Engineering: We provide specialized customization for rare and non-standard frequencies that other suppliers refuse.

Technical Edge: Our R&D focuses on the most demanding specs—from ultra-low phase noise floor to long-term aging stability.

Flexible Manufacturing: We support everything from low-volume specialized runs to high-capacity industrial supply, ensuring no project is too small for elite timing.

Legacy Support: We assist in sourcing and designing drop-in replacements for discontinued or hard-to-find oscillators.

Our Core Product Lineup

OCXO (Oven-Controlled Crystal Oscillators): Including Double-Oven and Ultra-Low Noise versions for telecommunications and aerospace.

TCXO (Temperature-Compensated Crystal Oscillators): High-reliability solutions for portable and industrial applications.

VCXO (Voltage-Controlled Crystal Oscillators): Precision tuning for phase-locked loops (PLL) and signal processing.

Our Commitment to Quality

We believe that in the world of timing, a micro-deviation can mean a total system failure. That’s why every Xtal-Long component undergoes rigorous testing to meet global standards. We are your reliable partner in frequency control, dedicated to ensuring that your innovation is backed by the most stable clock sources available.
