18QHTF21-27.3972-OE

Oscillators Overview

The 18QHTF21-27.3972-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 27.3972 MHz and utilizes LVCMOS output logic. The component functions with a supply voltage of 1.8V and includes enable/disable control capabilities. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable functionality for power management
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• General purpose timing clock generation
• Embedded system microcontroller clocks
• Digital signal processing circuits

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 footprint matches your PCB layout constraints. Cross-reference the OE suffix with manufacturer documentation to confirm any specific testing or binning requirements associated with this variant.

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 devices needing power conservation. Consider the small form factor if space is limited on the printed circuit board. Validate that the 27.3972 MHz frequency meets the exact timing needs of the target application without requiring external dividers.
