840C-12-1

Oscillators Overview

The Fox Electronics 840C-12-1 is a Voltage-Controlled Temperature Compensated Crystal Oscillator (VCTCXO) designed for surface-mount applications. It operates at a nominal frequency of 12.000 MHz and delivers a clipped sine wave output signal. The device functions within a supply voltage range of 2.5V to 3.3V, with typical operation at 3.3V. It ensures high frequency stability of ±2ppm across an extended operating temperature range from -30°C to +85°C. The component is housed in a compact SMD package, suitable for space-constrained designs requiring precise timing control.

Oscillators Feature Summary

• Integrates voltage control and temperature compensation for enhanced frequency accuracy
• Delivers clipped sine wave output suitable for various digital interfaces
• Operates reliably across wide industrial temperature ranges

Oscillators Applications

• Wireless communication modules requiring stable clock sources
• Portable electronic devices with strict power and size constraints
• Industrial control systems needing precise timing under variable temperatures

Oscillators Procurement Notes

Verify the specific pinout configuration and control voltage characteristics against the official datasheet before integration. Confirm that the supply voltage requirements align with the system's power rails, as the device supports a range between 2.5V and 3.3V. Ensure thermal management strategies account for the specified operating temperature limits to maintain the stated frequency stability. Cross-reference the package dimensions with the PCB footprint design to ensure mechanical compatibility.

Oscillators Selection Notes

Select this component when both voltage tuning capability and temperature compensation are required within a single surface-mount package. It is appropriate for designs prioritizing frequency stability over a wide thermal range without external compensation circuits. Consider the clipped sine wave output format when evaluating interface compatibility with downstream logic or RF stages. Evaluate the trade-off between the ±2ppm stability and the available control voltage range for the specific application needs.
