18QHTF21-28.59375-OE

Oscillators Overview

The 18QHTF21-28.59375-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 28.59375 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes hardware enable/disable functionality for power management
• Utilizes a leadless SMD package for automated assembly

Oscillators Applications

• General purpose clock generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interfaces requiring stable clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before ordering. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official datasheet to prevent mounting issues during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling levels. The enable pin allows for dynamic power saving in battery-operated devices. Consider the operating temperature range specified in the datasheet to ensure reliability under environmental stress conditions typical of the intended application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within the same form factor. The series is characterized by its small footprint and low power consumption. Similar models in the lineup differ primarily in output frequency and potentially supply voltage options, allowing for flexible design integration across different electronic products.

Oscillators Replacement Considerations

Direct substitutes include other 28.59375 MHz oscillators with identical 1.8V LVCMOS specifications and 4-SMD packages. Verify pinout compatibility and electrical parameters such as phase noise and jitter before swapping. Alternative parts must support the enable/disable feature if power management is critical to the design.
