Overview
The 18QHTF21-7.3727-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.3727 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, designed for surface-mount applications requiring precise timing signals.
Feature Summary
- LVCMOS output logic for digital interface compatibility
- Integrated enable and disable functionality for power management
- Compact 4-SMD no-lead surface mount package design
Applications
- General clock signal generation in embedded systems
- Timing reference for low-voltage digital circuits
- Consumer electronics requiring precise frequency standards
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 no-lead package 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 LVCMOS output compatibility. The enable/disable feature supports power-sensitive designs needing active control over the clock signal. Consider the small form factor of the 4-SMD package for space-constrained applications where standard leaded packages are unsuitable.
