Overview
The 18QHTF21-73.63636-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 73.63636 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, suitable for surface-mount applications requiring precise timing signals.
Feature Summary
- Supports active enable and disable functionality for power management
- Delivers LVCMOS output logic levels
- Utilizes a leadless SMD package for space-constrained designs
Applications
- Digital signal processing systems
- Communication equipment clock sources
- Embedded system timing references
Procurement Notes
Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the enable/disable feature and voltage rating. Ensure the required operating temperature range matches the component specifications before procurement. Cross-reference the part number with authorized distributors to validate authenticity and current availability status.
Selection Notes
Select this component when a 1.8V supply and LVCMOS interface are required. The enable pin allows for dynamic power control. Verify that the 4-SMD no-lead footprint aligns with the PCB layout constraints. Confirm that the 73.63636 MHz frequency meets the system timing requirements without additional synthesis.
Part Context
This oscillator belongs to the Mercury Electronics 18QHTF series, characterized by low-voltage operation and small form factors. The series supports various frequencies and output types, catering to portable electronics and high-density circuit boards where size and power efficiency are critical design parameters.
Replacement Considerations
Direct substitutes include other 1.8V LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Ensure frequency tolerance and load capacitance match the original design. Verify that alternative parts support the same enable/disable control scheme if power management is required.
