High-Stability Oven Controlled Crystal Oscillator 80MHz | 14×14mm Compact SMT Package
Product Overview
The 80MHz OCXO series is a state-of-the-art Oven Controlled Crystal Oscillator designed for mission-critical RF and microwave applications. It delivers an industry-leading phase noise floor of -173dBc/Hz with exceptional frequency stability of ±0.3 ppm across an extended temperature range of -40°C to +95°C. Housed in a miniature 14x14mm SMT package, it provides the ultimate signal purity required for modern radar and high-end synthesizers where PCB space is limited.
Key Features
Extreme Phase Noise Performance: Reaches -173 dBc/Hz noise floor at 100kHz offset.
Compact Miniature Design: Small 14.0 x 14.0 mm surface mount footprint (SMT).
High Temperature Capability: Reliable operation up to +95°C, suitable for military and aerospace environments.
Tight Frequency Stability: ±0.3 ppm over the entire temperature range (-40°C to +95°C).
Clean Sine Wave Output: High signal integrity with spurious suppression better than -80dBc.
Frequency Control (EFC): Positive control slope for precise frequency adjustment via voltage (0-5.0VDC).
Applications
Radar Systems: Low phase noise ensures superior target resolution and Doppler accuracy.
High-End Instrumentation: Reference clocks for signal generators and spectrum analyzers.
Satellite Communications (SATCOM): Stable reference for up/down conversion in ground stations.
Radio Frequency (RF) Synthesis: Pure clock source for low-noise frequency synthesizers.
