Recently, Saisi has made a major breakthrough in its 100MHz Oven Controlled Crystal Oscillator (OCXO). Its measured phase noise at 1kHz offset reaches ≤-170.03dBc/Hz, setting a new performance benchmark for peer-frequency OCXOs and delivering cutting-edge solutions for core sectors including 6G base stations and high-end radars.
1. Generational Leap in Phase Noise: Saisi OCXO Ranks Among Global Leaders
Crystal oscillators serve as the "heart" of high-end electronic devices, while phase noise acts as a core indicator for evaluating signal spectral purity and system background noise. For sophisticated electronic equipment, low-phase-noise reference signals are equivalent to pure bloodstream for the whole system, directly determining equipment anti-interference capability, measurement sensitivity and communication stability. They are indispensable core components for 5G-A/6G, radar, satellite communication and other high-end industries.
Conventional 100MHz OCXOs generally feature around -159dBc/Hz phase noise at 1kHz offset, while mid-to-high-end products have long been confined within -160~-165dBc/Hz, leaving a noticeable performance gap against world-class standards. Globally, mainstream top-tier products register 1kHz offset phase noise ranging from -168 to -172dBc/Hz, with typical far-offset phase noise at approximately -177dBc/Hz.
Boasting measured phase noise of -170.03dBc/Hz@1kHz, Saisi 100MHz OCXO has secured a position among global top-tier products. Its far-offset phase noise hits -187.34dBc/Hz@1MHz, far exceeding the industry background noise threshold, fully demonstrating Saisi’s robust intelligent manufacturing strength.
2. Beyond Ultra-Low Phase Noise: An All-Round Premium Signal Core
It is widely acknowledged that ultra-low phase noise of traditional crystal oscillators usually comes with drawbacks including high power consumption, bulky size and narrow operating temperature range. To meet stringent spectral purity requirements of 6G golden frequency bands as well as time-frequency precision demands arising from AI-RAN, integrated communication-sensing and other emerging scenarios, Saisi 100MHz OCXO achieves ultra-low phase noise while optimizing multiple practical engineering parameters, realizing dual advantages of superior performance and easy deployment for diversified application scenarios.
High Frequency Stability: Second-level stability up to 8E-14/s ensures highly precise and steady signal output, building an ultra-stable signal core for high-end devices.
Wide Temperature Adaptability: Supports operating temperatures from -40~+85℃ to -55~+105℃, suitable for harsh extreme working conditions.
Diversified Specifications: Available in full DIP and SMD packages with 9 size options ranging from 928292mm to 7.75.53.3mm. It supports sine wave and square wave outputs with optional 3.3V/5V/12V supply voltages, fully compatible with various hardware integration requirements.
3. Sustained Innovation to Forge Ahead in Time-Frequency Industry
As a professional enterprise dedicated to the time-frequency industry, Saisi takes technological innovation as its core driving force, focuses on key technical bottlenecks in high-end time-frequency field, and keeps long-term investment in core technology R&D. Supported by its self-owned 36,000-square-meter production base, Saisi crystal oscillators are manufactured via large-scale automated production lines to ensure stable and sufficient product supply.
