Overview

The LFTVXO085763 is a high-precision 20 MHz Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) from IQD Frequency Products. Operating at 3.3V, this HCMOS output oscillator offers exceptional frequency stability of +/-50ppb across a wide industrial temperature range from -40C to 105C. It features integrated amplitude control, allowing engineers to fine-tune the output frequency for precise synchronization requirements.

Why Choose This Part

This VCTCXO provides an extremely tight frequency stability of +/-50ppb, making it suitable for high-end timing applications that typically require larger OCXOs. Its wide operating temperature range up to 105C ensures reliability in harsh industrial environments, while the VCTCXO functionality allows for external frequency trimming and phase-locked loop integration.

Applications

GNSS Synchronization
Providing a stable reference clock for GPS and navigation systems that require high frequency accuracy for precise positioning.
Industrial Communications
Acting as a master clock in Ethernet or wireless infrastructure where low jitter and high thermal stability are critical.
Base Station Timing
Maintaining clock alignment in cellular small cells and distributed antenna systems across varying environmental temperatures.
Test and Measurement
Serving as a reliable frequency source for portable instrumentation requiring better stability than standard XO or TCXO components.

Getting Started

When integrating this 7.0mm x 5.0mm SMD component, ensure a clean 3.3V supply with local decoupling capacitors to maintain frequency purity. Designers should provide a control voltage to pin 1 if frequency adjustment is required, or tie it to a stable reference if fixed-frequency operation is intended. Follow standard reflow profiles for 4-SMD leadless packages, ensuring the thermal pad is correctly soldered for stability.
