18QHTF21-2.21184-OE

Oscillators Overview

The 18QHTF21-2.21184-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fundamental frequency of 2.21184 MHz and utilizes an LVCMOS output interface. The device is designed for a supply voltage of 1.8V and features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports Enable/Disable functionality for active power management
• Utilizes LVCMOS output signal compatibility
• Operates on a 1.8V supply voltage
• Housed in a small form factor 4-SMD No Lead package

Oscillators Applications

• General purpose timing circuits requiring low power consumption
• Embedded systems utilizing LVCMOS logic interfaces
• Portable electronic devices necessitating compact oscillator footprints

Oscillators Procurement Notes

Verify the specific suffix 'OE' confirms the Enable/Disable feature rather than Standby or other variants. Ensure the operating voltage matches the 1.8V requirement of the target circuit design. Confirm the package footprint aligns with the 2.0x1.6 mm SMD land pattern specifications provided in the official datasheet to prevent assembly issues.

Oscillators Selection Notes

Select this component when a precise 2.21184 MHz frequency is required alongside low voltage operation. The Enable/Disable pin allows for dynamic power control, making it suitable for battery-operated applications. Compare against similar models like the -PD variant if standby functionality is preferred over enable/disable control.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and control options, including Enable/Disable and Standby modes. These oscillators are designed for high reliability in consumer electronics and industrial applications requiring stable clock signals.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-2.21184-PD, which shares the same frequency and package but uses Standby instead of Enable/Disable control. Other frequency variants within the 18QHTF21 series may be considered if different timing requirements exist.
