18QHTF21-6.51755-OE

Overview

The 18QHTF21-6.51755-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 6.51755 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 with dimensions of 2.0mm x 1.6mm. The component supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Includes hardware enable and disable control functionality
• Utilizes a surface-mount 4-SMD no-lead package design

Applications

• General-purpose timing clock generation
• Embedded system synchronization
• Digital signal processing circuits

Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm the exact electrical characteristics and pinout configuration. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs before finalizing procurement decisions.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise frequency stability. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. Consider the enable/disable feature if power management during idle states is necessary for the application.

Part Context

This part belongs to the Mercury Electronics 18QHTF series of surface-mount crystal oscillators. The series offers various frequencies and voltage options. The 18QHTF21 variant specifically denotes the package type and form factor within the manufacturer's portfolio of timing solutions.

Replacement Considerations

Cross-reference with other 1.8V LVCMOS oscillators in the same 4-SMD no-lead package. Verify frequency tolerance and operating temperature ranges match the original specifications before substitution.
