18QHTF21-30.420-OE

Oscillators Overview

The 18QHTF21-30.420-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 30.42 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your power management architecture. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to guarantee proper soldering and electrical connection.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable feature allows for power management during idle states. Consider the 4-SMD package size for space-constrained designs. Verify that the 30.42 MHz frequency meets the system clock requirements without additional dividers or multipliers.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same package and voltage profile. The series provides standardized timing solutions for consumer and industrial electronics. The 'OE' suffix typically denotes the enable pin configuration, distinguishing it from free-running variants.

Oscillators Replacement Considerations

Direct replacements must match the 1.8V supply, LVCMOS output, and 4-SMD package. Check equivalent models from other manufacturers offering 30.42 MHz oscillators with identical pinouts and electrical characteristics to ensure seamless integration without redesign.
