VMQF574T25-16.392658-1.0/-40+85

Oscillators Overview

The VMQF574T25-16.392658-1.0/-40+85 is a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 16.392658 MHz with a CMOS output type. The device requires a 2.5V supply voltage and provides high frequency stability of ±1ppm. It features an Absolute Pull Range (APR) of ±8ppm and functions within an operating temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Integrates temperature compensation for stable frequency performance across wide thermal variations
• Provides precise frequency control via voltage input within specified pull range
• Delivers standard CMOS logic level output signals

Oscillators Applications

• Wireless communication modules requiring stable clock sources
• Portable electronic devices with limited power budgets
• Industrial control systems operating in variable environmental temperatures

Oscillators Procurement Notes

Verify the specific frequency tolerance and APR requirements against system specifications before ordering. Confirm that the 2.5V supply voltage aligns with the target circuit design. Ensure the operating temperature range meets the environmental conditions of the intended application. Check for any specific packaging or reel requirements if using automated assembly processes.

Oscillators Selection Notes

Select this component when a compact VCTCXO solution is needed for applications demanding high stability without the complexity of oven-controlled oscillators. Consider the ±8ppm pull range to ensure sufficient frequency adjustment capability for the system. Evaluate the CMOS output compatibility with downstream digital interfaces. Compare power consumption characteristics against other available oscillator types for optimal efficiency.

Oscillators Part Context

This model belongs to the VMQF series of VCTCXOs from Mercury Electronics, designed for cost-sensitive applications requiring better stability than standard TCXOs. The suffix indicates specific frequency, voltage, tolerance, and temperature grade parameters unique to this variant within the broader product family.

Oscillators Replacement Considerations

Direct substitutes must match the 16.392658 MHz frequency, 2.5V supply, CMOS output, and ±1ppm stability. Verify pinout compatibility and physical dimensions to ensure board-level interchangeability without redesigning the PCB footprint.
