Overview
The 18QHTF21-10.5375-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.5375 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.
Feature Summary
- Provides stable clock signals via LVCMOS output interface
- Includes hardware enable/disable functionality for power optimization
- Designed for surface-mount integration using leadless SMD packaging
Applications
- General digital circuit timing reference
- Embedded system clock generation
- Consumer electronics timing control
Procurement Notes
Verify the specific suffix OE against official Mercury Electronics documentation to confirm pinout and electrical characteristics match your design requirements. Ensure the 1.8V supply rail is stable and within tolerance. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs of your target application before finalizing procurement.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS compatibility. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the 4-SMD no-lead package dimensions for PCB layout constraints compared to other oscillator series from the manufacturer.
Part Context
This part belongs to the Mercury Electronics XO (Standard) series, which focuses on cost-effective, general-purpose oscillators. The 18QHTF21 series typically denotes specific size and performance tiers within their portfolio, offering reliable quartz-based frequency control for mainstream electronic applications without specialized temperature compensation.
Replacement Considerations
Direct substitutes may include other 10.5375 MHz LVCMOS oscillators in similar 4-SMD packages from Mercury Electronics, such as variants with different suffixes if electrical parameters align. Cross-reference with Mercury's current product listings for equivalent frequency and voltage specifications.
