18QHTF21-25.011-OE

Oscillators Overview

The 18QHTF21-25.011-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 25.011 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports enable/disable control for efficient power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Designed as a standard XO (Crystal Oscillator) unit

Oscillators Applications

• Digital signal processing systems
• Communication equipment timing references
• Embedded microcontroller clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific environmental ratings if operating in extreme temperatures.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the 4-SMD form factor for space-constrained boards. Compare against other Mercury QHTF series variants if different frequencies or voltages are needed.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The '18' prefix indicates the 1.8V supply voltage requirement, while '25.011' specifies the nominal frequency. The '-OE' suffix typically denotes a specific packaging or tape-and-reel configuration offered by distributors.

Oscillators Replacement Considerations

Direct substitutes within the same family include other QHTF models with matching voltage and package, such as the 18QHTF21-48.900-OE for different frequencies. Verify pinout compatibility and electrical characteristics before swapping. Cross-reference with distributor cross-reference lists for equivalent parts from other manufacturers.
