18QHTF21-27.100-OE

Oscillators Overview

The 18QHTF21-27.100-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 27.1 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Integrates enable and disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Employs a leadless SMD package for automated assembly

Oscillators Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded microcontroller timing sources

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target circuit design. Confirm that the 1.8V supply rail stability meets the oscillator's jitter specifications. Ensure PCB layout guidelines for the 4-SMD no-lead package are followed to maintain signal integrity and thermal performance during soldering processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS outputs. The enable/disable feature supports dynamic power saving strategies in battery-operated devices. Consider the small form factor of the 4-SMD package for space-constrained designs where surface-mount technology is preferred over through-hole alternatives.

Oscillators Part Context

This model belongs to the Mercury Electronics XO series, which focuses on quartz-based frequency control solutions. The manufacturer has established expertise in Taiwan's crystal industry since 1973. This specific part represents a standard frequency option within their portfolio of surface-mount oscillators designed for general-purpose timing applications.

Oscillators Replacement Considerations

Direct substitutes include other 27.1 MHz LVCMOS oscillators with identical 1.8V supply and 4-SMD no-lead footprints from compatible manufacturers. Verify pinout compatibility and electrical parameters before swapping. Alternative models may offer different enable logic or temperature ranges but must match the physical package dimensions.
