18QHTF21-24.560-OE

Oscillators Overview

The 18QHTF21-24.560-OE is a standard quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 24.56 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning with a supply voltage of 1.8V. It features an enable/disable control input (OE) for power management flexibility. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm, suitable for space-constrained surface-mount designs.

Oscillators Feature Summary

• LVCMOS output compatibility for direct interface with digital logic circuits
• Integrated enable/disable functionality via the OE pin for power optimization
• Compact 4-SMD no-lead package design facilitating automated assembly

Oscillators Applications

• High-performance embedded systems requiring precise clock signals
• Portable electronic devices utilizing low-voltage power supplies
• Communication modules needing stable frequency references

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 PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent soldering issues during assembly.

Oscillators Selection Notes

Select this oscillator when a 24.56 MHz reference is required in a minimal footprint. Consider the 1.8V operating voltage constraint compared to higher voltage alternatives. Evaluate the need for active enable/disable control versus always-on operation based on system power efficiency goals.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within standardized packages. The 18 prefix indicates the 1.8V supply variant, while the 21 suffix typically denotes the specific package type or performance grade within the product line.

Oscillators Replacement Considerations

Direct substitutes must match the 24.56 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility, specifically the OE pin configuration, to ensure seamless integration without PCB redesign.
