18QHTF21-21.760-OE

Oscillators Overview

The 18QHTF21-21.760-OE is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 21.76 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 2.0x1.6 mm, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for standard digital logic compatibility
• Integrated enable/disable pin for active power control
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• Timing and clock generation circuits
• Digital signal processing systems
• Communication equipment modules

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6 mm SMD package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The integrated enable feature makes it suitable for battery-powered or power-sensitive designs. Consider the small form factor if board space is limited. Verify that the 21.76 MHz frequency meets the exact timing needs of the target application without requiring external dividers.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies within a standardized 2.0x1.6 mm package. The suffix OE indicates specific packaging or tape-and-reel configuration details defined by the manufacturer. This model represents a standard XO variant optimized for general-purpose timing applications.

Oscillators Replacement Considerations

Direct substitutes must match the 21.76 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Check equivalent parts from other manufacturers like Epson or SiTime that offer similar voltage and form factor specifications.
