Overview
The 18QHTF21-10.625-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.625 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 clock signals.
Feature Summary
- Integrates LVCMOS output logic for digital interface compatibility
- Supports active enable and disable control states
- Utilizes a leadless SMD package for automated assembly
Applications
- Digital signal processing clock generation
- Embedded system timing references
- Communication equipment synchronization
Procurement Notes
Verify the specific suffix 'OE' against the manufacturer's current datasheet to confirm the enable/disable functionality and voltage level. Ensure the 4-SMD no-lead footprint matches the PCB land pattern. Confirm that the 1.8V supply requirement aligns with the target circuit design before procurement.
Selection Notes
Select this component when a 10.625 MHz reference is required with low-voltage operation. The enable feature allows for power management in battery-operated devices. Compare jitter specifications and operating temperature ranges against application requirements to ensure signal integrity and reliability under expected environmental conditions.
Part Context
This part belongs to the Mercury Electronics XO series, which provides quartz-based frequency control solutions. The company specializes in manufacturing various oscillators and resonators. This specific model represents a standard frequency option within their portfolio of surface-mount clock generators.
Replacement Considerations
Direct substitutes must match the 10.625 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics. Consult official cross-reference lists from Mercury Electronics or authorized distributors for validated equivalent part numbers.
