18QHTF21-69.3755-OE

Overview

The 18QHTF21-69.3755-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 69.3755 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 2.0x1.6mm.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features enable/disable pin control for power management
• Utilizes a surface-mount SMD package for automated assembly

Applications

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

Procurement Notes

Verify the specific suffix OE against the manufacturer's official documentation to confirm the presence of the enable/disable function and exact electrical characteristics. Ensure the operating temperature range and load capacitance requirements align with the target circuit design before finalizing procurement orders.

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. Confirm that the LVCMOS output swing matches the input thresholds of the receiving logic gates in the application circuit.

Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The manufacturer specializes in quartz crystals and oscillators, offering various packages and voltage options to meet diverse electronic timing requirements across industrial and consumer applications.

Replacement Considerations

Direct substitutes must match the 69.3755 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and enable/disable functionality equivalence with alternative manufacturers' components.
