In today's era where smart medical devices are evolving towards high precision and miniaturization, electromagnetic interference (EMI) has become an inescapable nightmare for R&D engineers. Particularly in the fields of imaging diagnosis and biochemical analysis, minute electromagnetic noise may directly lead to diagnostic misjudgments.
The YXC Yangxing Technology-developed YSO171PS series programmable spread spectrum oscillator (SSXO) addresses EMI challenges at the source through its proprietary frequency modulation technology, providing rock-solid timing support for intelligent diagnostic and therapeutic devices.
Core Technology: Why Spread Spectrum (SSXO) is EMI's' Best Friend'
Traditional crystal oscillators concentrate energy at extremely narrow frequency points, which can easily generate exceptionally high electromagnetic radiation peaks.
The YXC Yangxing Technology Spread Spectrum Crystal Oscillator Series YSO171PS employs unique spread spectrum modulation technology to evenly distribute concentrated energy across a wider frequency band, significantly reducing harmonic energy density without compromising system clock accuracy.
This "peak shaving and valley filling" approach enables medical devices to effortlessly comply with stringent Electromagnetic Compatibility (EMC) standards for medical devices (e.g., IEC 60601-1-2), significantly reducing the Time-to-Market for product launch.
Deep Adaptation: Empowering Three Core Scenarios of Smart Diagnosis and Treatment
1. High-end imaging equipment: Elimination of "image noise"
In endoscopes, ultrasound diagnostic systems, and similar equipment, high-frequency circuits are densely distributed. The YXC Yangxing Technology frequency-shifting crystal oscillator YSO171PS suppresses high-frequency EMI radiation, ensuring interference-free analog signal acquisition. This fundamentally guarantees image purity and contrast, enabling physicians to accurately identify lesions.
2. Precision testing instruments: Enhancing "signal-to-noise ratio"
Biochemical analyzers and hemoglobin testers exhibit exceptional sensitivity in weak signal capture. The frequency-division crystal oscillator smooths out energy peaks, effectively enhancing the signal-to-noise ratio of weak current signals and ensuring that test data maintains high repeatability and accuracy even under complex hospital electromagnetic environments.
3. Portable Mobile Healthcare: Balancing "Miniaturization and Low Power Consumption"
For mobile ECG monitoring and smart blood pressure monitors, the YSO171PS series offers extremely compact packaging dimensions and low power consumption performance. Within confined spaces, there is no need for additional expensive shielding covers or complex components.
