The 18QHTF21-24.545-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 24.545 MHz and utilizes LVCMOS output logic levels. The device is designed for operation with a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output signal format
• Integrates enable and disable control functionality
• Operates on a 1.8V power supply

Oscillators Applications

• Digital communication systems requiring precise timing
• Embedded microcontroller clock sources
• Portable electronic devices with space constraints

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 architecture. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-profile surface-mount oscillator is required for 1.8V logic interfaces. The 2.0x1.6 mm package size suits applications with strict spatial limitations. Consider the enable/disable feature if power management or clock gating is necessary within the target design to optimize energy consumption.

Oscillators Part Context

This part belongs to the QHTF series from Mercury Electronics, which offers various hermetic ceramic leadless SMD packages. The series supports frequencies ranging from 1.0 MHz to 200 MHz across different supply voltages. This specific model represents a standard XO variant optimized for compact digital applications.

Oscillators Replacement Considerations

Direct substitutes must match the 24.545 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications to ensure functional equivalence in the existing circuit design.
