18QHTF21-7.3704-OE

Overview

The 18QHTF21-7.3704-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 7.3704 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 compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• Timing and clock signal generation in electronic devices
• High-performance application circuits
• Digital system synchronization

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS interface compatibility. The integrated enable pin allows for power management control within the system. Consider the small form factor suitable for space-constrained designs where surface-mount technology is preferred over through-hole alternatives.

Part Context

This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized 4-pin package. These oscillators are designed to provide stable clock signals for digital circuits, differing from other Mercury products like TCXOs or VCXOs which offer temperature compensation or voltage control features respectively.

Replacement Considerations

Direct substitutes include other 7.3704 MHz LVCMOS oscillators in 4-SMD packages with 1.8V supply and enable pins. Verify pinout compatibility and electrical parameters such as current consumption and startup time before substitution.
