18QHTF21-26.9973-PD

Oscillators Overview

The 18QHTF21-26.9973-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 26.9973 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes a standby or power-down control feature for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component is designed for applications requiring precise timing signals within a small form factor.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby or power-down control functionality
• Compact 4-SMD no lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Embedded systems timing reference
• Portable electronic devices

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. 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 guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The integrated power-down feature makes it suitable for battery-operated devices where power conservation is critical. Consider the small 2.0x1.6mm package size if space constraints are a primary design factor compared to larger oscillator packages.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature crystal oscillators. The series typically offers various frequencies and voltage options. The 'PD' suffix indicates the inclusion of a power-down or standby pin, distinguishing it from models without this control feature. This series is part of Mercury's long-standing expertise in quartz crystal manufacturing.

Oscillators Replacement Considerations

Direct replacements must match the 26.9973 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify that substitute parts also include the power-down control feature. Cross-reference with other Mercury 18QHTF21 variants or competitors offering identical electrical and mechanical specifications.
