100.00MHz Ultra-Low Phase Noise VCXO – 18fs RMS Jitter Performance
Product Overview:
This 100MHz VCXO sets a new standard for timing precision, delivering an industry-leading RMS Phase Jitter of ≤18fs (12kHz to 20MHz). Housed in a robust 14.0×9.0mm SMD package, it is engineered for applications where signal purity is critical.
With a remarkable phase noise floor of -176dBc/Hz @10MHz and a wide operating temperature range of -40°C to +95°C, this voltage-controlled oscillator provides the stable, high-frequency reference needed for next-generation radar, high-speed data converters, and advanced telecommunications.
Key Performance Highlights:
Elite Jitter Performance: ≤18fs RMS Phase Jitter for high-speed sampling.
Extreme Phase Noise: -170dBc/Hz @100kHz and -176dBc/Hz noise floor.
Extended Temperature: Reliable performance up to +95°C (surpassing standard industrial grades).
Precision Tuning: ≥±25ppm adjustment range with excellent linearity.
Compact SMD Footprint: 14.0 x 9.0 x 3.0mm (standard footprint).
Target Applications:
High-Speed Data Conversion: Clocking for high-performance ADCs and DACs.
Defense & Aerospace: Radar systems, electronic warfare, and guidance.
Medical Equipment: High-resolution MRI and ultrasound imaging.
Test & Measurement: Phase noise analyzers and high-end synthesizers.
