18QHTF21-14.640-OE

Oscillators Overview

The 18QHTF21-14.640-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a frequency of 14.64 MHz and utilizes LVCMOS output logic. The device supports 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

• 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 exact frequency specification against official datasheets, as similar part numbers may differ slightly (e.g., 14.46406 MHz). Confirm the 1.8V supply voltage requirement and LVCMOS output type match the target design. Ensure the 4-SMD package footprint aligns with PCB layout constraints before ordering.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable feature allows for power management in battery-operated devices. Consider the small form factor for space-constrained designs. Verify temperature range requirements if operating outside standard commercial limits.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronic, a supplier specializing in quartz crystals and timing solutions. The series typically offers various frequencies within a standardized 4-SMD package. Mercury has been manufacturing frequency control products since 1973, focusing on reliability in timing applications.

Oscillators Replacement Considerations

Direct substitutes include other 14.64 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Ensure voltage levels and pin configurations match. Cross-reference with Mercury's own variants like 18QHTF21-14.46406-OE only if frequency tolerance permits.
