Overview
The 18QHTF21-13.105-OE is an active crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 13.105 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component is designed for standard clock signal generation applications requiring precise timing references.
Feature Summary
- LVCMOS output logic for digital interface compatibility
- Integrated enable and disable control functionality
- Compact surface-mount package design
Applications
- Standard clock signal generation
- Digital system timing references
- Embedded controller clock sources
Procurement Notes
Verify the specific datasheet version and electrical characteristics directly from Mercury Electronics Ind. Co. Ltd official documentation before integration. Confirm that the 1.8V supply voltage and LVCMOS output levels align with the target circuit requirements. Ensure the 2.0x1.6mm footprint matches the PCB layout specifications to avoid assembly issues.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable feature allows for power management optimization in battery-operated or standby-sensitive designs. Consider the small 2.0x1.6mm package size for space-constrained layouts where standard larger oscillators cannot fit.
Part Context
This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small outline package. The 'OE' suffix often denotes specific packaging or tape-and-reel configurations, though verification against the manufacturer's ordering guide is necessary for confirmation.
Replacement Considerations
Direct substitutes must match the 13.105 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm footprint. Verify pinout compatibility and electrical parameters such as load capacitance and drive strength. Cross-reference with other Mercury Electronics parts in the same series if available.
