18QHTF21-27.456-OE

Oscillators Overview

The 18QHTF21-27.456-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 27.456 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features integrated enable and disable control functionality
• Utilizes quartz-based crystal technology for frequency stability

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference sources for embedded systems
• Digital communication interfaces requiring precise clocking

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application design specifications. Confirm that the 1.8V supply voltage aligns with the system power architecture. Ensure the 4-SMD no-lead package footprint matches the PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 27.456 MHz frequency. The small 2.0x1.6 mm form factor makes it suitable for space-constrained designs. Consider the enable/disable pin if power management or clock gating is necessary within the system architecture.

Oscillators Part Context

This part belongs to the Mercury Electronics XO (Standard) series, which focuses on providing reliable quartz-based oscillators. The manufacturer has extensive experience in frequency control products, positioning this model as a standard solution for general-purpose timing applications requiring specific frequency outputs.

Oscillators Replacement Considerations

Direct substitutes include other 27.456 MHz LVCMOS oscillators from Mercury Electronics such as the 18QHTF21-27.456 variant, provided the package and voltage specifications remain identical. Cross-manufacturer replacements require matching frequency, voltage, and package dimensions.
