18QHTF21-14.74772-OE

Oscillators Overview

The 18QHTF21-14.74772-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 14.74772 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• LVCMOS output logic for digital signal compatibility
• Integrated enable and disable control functionality
• Low voltage operation at 1.8V supply
• Surface-mount 4-SMD no lead package design

Oscillators Applications

• Digital clock generation in embedded systems
• Timing reference for microprocessors
• Synchronization in communication interfaces
• Power management circuits requiring precise timing

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 4-SMD no lead package dimensions provided in the official datasheet to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 14.74772 MHz timing source is required for LVCMOS-compatible digital logic. The choice is driven by the need for low-power operation at 1.8V and the convenience of integrated enable/disable controls. 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 oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series includes various frequencies such as 21.2 MHz and 13.1313 MHz, all sharing similar packaging and electrical characteristics like 1.8V operation and LVCMOS outputs. This model specifically targets applications needing the 14.74772 MHz standard frequency.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical pinout and electrical specs but different frequencies, such as 18QHTF21-21.200-OE or 18QHTF21-13.1313-OE, if frequency adjustment is permissible. Cross-brand replacements must match the 1.8V LVCMOS specification and 4-SMD no lead package dimensions.
