Overview
The 18QHTF21-75.380-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 75.38 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 suitable for surface mount applications.
Feature Summary
- Supports enable and disable functionality for power management
- Utilizes LVCMOS output logic for digital interface compatibility
- Designed for surface mount assembly via 4-SMD no lead package
Applications
- Computing systems requiring precise clock signals
- Data communication equipment
- Consumer electronics devices
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 dimensions to guarantee proper solder joint formation and mechanical stability during operation.
Selection Notes
Select this component when a low-voltage 1.8V supply is required alongside LVCMOS outputs. The enable/disable feature makes it suitable for battery-powered applications where power conservation is critical. Consider the 4-SMD no lead package size if space constraints are a primary design factor for the target electronic assembly.
Part Context
This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies within a similar form factor. Mercury Electronics has decades of experience in quartz crystal manufacturing, positioning this component within their established portfolio of frequency control solutions for industrial and commercial markets.
Replacement Considerations
Direct substitutes include other 18QHTF21 variants with matching 75.38 MHz frequency and 1.8V LVCMOS specifications. Verify pinout compatibility and thermal characteristics when cross-referencing with alternative manufacturers' offerings to ensure seamless integration without redesigning the host circuit board.
