18QHTF21-24.690-OE

Oscillators Overview

The 18QHTF21-24.690-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 24.69 MHz and utilizes an LVCMOS output signal format. The device supports 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, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports enable and disable control functions for active power management
• Generates LVCMOS output signals for digital logic compatibility
• Utilizes a leadless SMD package for automated surface-mount assembly

Oscillators Applications

• Digital clock generation in embedded systems
• Timing reference for microcontroller units
• Synchronization in communication interfaces

Oscillators Procurement Notes

Verify the specific suffix 'OE' confirms the enable/disable functionality distinct from other variants like 'PD'. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm the 4-SMD no-lead footprint matches the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 24.69 MHz timing source with low-power standby capabilities is required. The LVCMOS interface ensures direct compatibility with standard digital logic families. Consider the 1.8V operating voltage constraint to ensure proper integration within the system's power distribution network.

Oscillators Part Context

This part belongs to the Mercury Electronic 18QHTF21 series of quartz crystal oscillators. The manufacturer specializes in frequency control products including crystals, TCXOs, and VCTCXOs. This specific model represents a standard XO variant optimized for general-purpose timing applications in consumer and industrial electronics.

Oscillators Replacement Considerations

The datasheet lists the 18QHTF21-24.690-PD as a related variant. However, the 'PD' suffix indicates a Power Down feature rather than the Enable/Disable function found in the 'OE' version. Verify that the control logic requirements match the specific switching behavior of the replacement part.
