18QHTF21-7.3333-OE

Overview

The 18QHTF21-7.3333-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.3333 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Integrates LVCMOS output interface for direct digital logic compatibility
• Features active enable/disable pin for dynamic power control
• Utilizes low-profile 4-SMD no-lead surface mount packaging

Applications

• Digital signal processing systems requiring stable clock sources
• Communication equipment utilizing LVCMOS interfaces
• Portable electronic devices necessitating low-power operation

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's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly issues. Cross-reference the datasheet for operating temperature ranges suitable for your environment.

Selection Notes

Select this component when a 7.3333 MHz clock signal is required with LVCMOS compatibility. Consider the 1.8V operating voltage constraint and the need for an enable/disable feature for power efficiency. The small 2.0x1.6mm package makes it suitable for space-constrained designs. Evaluate if the standard frequency accuracy meets your system's jitter and stability specifications.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized 4-SMD form factor. The suffix 'OE' indicates the inclusion of an output enable function, distinguishing it from basic continuous-output variants in the same package family.

Replacement Considerations

Direct replacements must match the 7.3333 MHz frequency, LVCMOS output type, 1.8V supply voltage, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as current consumption and drive strength. Alternative parts from other manufacturers require careful evaluation of thermal and mechanical constraints.
