25MHz SMD 2520 TCXO – Ultra-Compact High Stability Reference Clock
Product Overview:
The 25MHz TCXO in the SMD 2520 (2.5mm x 2.0mm) package is designed for space-constrained applications requiring superior frequency stability. Delivering ±0.5ppm precision across an extended temperature range, this oscillator features a Cliped Sine Wave output for reduced EMI. With a remarkably low current draw of only 1.5mA, it is the perfect timing solution for battery-powered devices, GPS/GNSS receivers, and modern telecommunication systems.
Key Features:
Ultra-Small Footprint: Compact 2.5 x 2.0 mm SMD package saves critical PCB real estate.
High Frequency Stability: Offers tight ±0.5ppm stability from -30°C to +85°C.
Low Phase Noise: Excellent performance with -130 dBc/Hz at 1kHz offset, ensuring high signal integrity.
Extreme Low Power: Consumes maximum 1.5mA, extending battery life in portable applications.
Wide Supply Voltage: Flexible operation from +1.7V to +3.3V.
Fast Start-up: Rapid initialization in less than 2ms.
EMI Optimized: Cliped Sine Wave output minimizes electromagnetic interference.
Ideal Applications:
GPS / GNSS Modules: High-precision reference for positioning and navigation systems.
Mobile Communications: Smartphones, wearables, and portable radio equipment.
IoT Devices: Low-power timing for smart sensors and connected devices.
