18QHTF21-86.963-OE

Overview

The 18QHTF21-86.963-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 86.963 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. The component is designed for applications requiring precise timing signals within a small form factor.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable control pin
• Compact 4-SMD no-lead surface mount package

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

Procurement Notes

Verify the specific frequency suffix matches the required 86.963 MHz specification. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD package footprint is compatible with the PCB layout. Check for any specific temperature range requirements if operating in extreme environments.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The small 2.0x1.6mm package makes it suitable for space-constrained designs. Consider the enable/disable feature if power efficiency during idle states is a priority. Verify that the standard XO type meets the phase noise and stability needs of the application.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 4-SMD package. The series supports 1.8V operation and LVCMOS outputs, providing a consistent interface across different frequency options. The -OE suffix typically denotes specific packaging or handling characteristics defined by the manufacturer.

Replacement Considerations

Direct substitutes must match the 86.963 MHz frequency, 1.8V supply, and LVCMOS output. Packages must be identical 4-SMD no-lead types with matching footprints. Cross-reference with other Mercury 18QHTF21 variants only if frequency differences are acceptable.
