Overview
The 18QHTF21-13.1072-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.1072 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.
Feature Summary
- LVCMOS output logic for digital interface compatibility
- Integrated enable/disable control functionality
- Compact 4-SMD no-lead surface mount package
Applications
- General clock signal generation
- Digital system timing references
- Embedded electronics circuits
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling levels. The enable/disable feature allows for power management strategies in battery-operated devices. Consider the small form factor of the 4-SMD package for space-constrained designs where minimal board area usage is critical for the overall product architecture.
Part Context
This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a consistent 4-SMD package. The 'OE' suffix typically denotes specific ordering or packaging variations defined by the manufacturer for distribution channels.
Replacement Considerations
Direct substitutes include other 18QHTF21 series variants such as 18QHTF21-4.31818-OE, 18QHTF21-13.1313-OE, 18QHTF21-50.256-OE, 18QHTF21-67.800-OE, and 18QHTF21-33.200-OE, provided the frequency difference is acceptable for the application.
