18QHTF21-18.306-OE

Oscillators Overview

The 18QHTF21-18.306-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 18.306 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and features an enable/disable control function to manage power consumption. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Enable/Disable control pin for power management
• Compact 4-SMD no-lead surface mount package

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 exact part number against official Mercury Electronics documentation to ensure correct voltage and package specifications. Confirm that the enable/disable functionality aligns with system power management requirements. Check for any specific ordering suffixes or revisions that may affect electrical characteristics or mechanical dimensions before finalizing procurement.

Oscillators Selection Notes

Select this component when a 1.8V supply voltage is required for low-power applications. Ensure the LVCMOS output swing is compatible with the receiving logic inputs. The enable/disable feature makes it suitable for battery-operated devices where power conservation during idle states is critical. Verify the 4-SMD footprint matches the PCB layout constraints.

Oscillators Part Context

This model belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series typically offers standard frequency options with LVCMOS outputs. The '18' prefix indicates the 1.8V operating voltage variant, distinguishing it from other voltage versions within the same family. The 'OE' suffix likely denotes a specific packaging or testing configuration provided by the manufacturer.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-18.306-PD, which shares the same frequency and voltage but uses a Standby (Power Down) control mode instead of Enable/Disable. Other variants in the 18QHTF21 series with different frequencies may serve as functional replacements if timing requirements differ.
