Overview
The 18QHTF21-72.115-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 72.115 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.
Feature Summary
- Supports LVCMOS output logic for digital interface compatibility
- Integrates enable and disable functionality for power management
- Utilizes a leadless SMD package for automated assembly
Applications
- General purpose clock generation
- Digital signal processing systems
- Communication equipment timing
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during operation.
Selection Notes
Select this component when a low-voltage 1.8V supply is required alongside LVCMOS outputs. The enable pin allows for dynamic power control, making it suitable for battery-operated or energy-efficient designs. Consider the leadless package profile if space constraints are critical within the target application environment.
Part Context
This model belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, which specializes in quartz-based frequency control products. The series typically offers various frequencies and voltage options, maintaining consistent packaging standards across different part numbers for easier inventory management and design reuse.
Replacement Considerations
Direct substitutes include other 18QHTF21 series variants with compatible frequencies such as 18QHTF21-72.000-OE or 18QHTF21-72.900-OE, provided the frequency difference is acceptable. Verify electrical parameters match exactly before substitution.
