18QHTF21-26.9865-OE

Oscillators Overview

The 18QHTF21-26.9865-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 26.9865 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an Enable/Disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• LVCMOS output interface for digital signal compatibility
• Integrated enable/disable control functionality
• Compact surface-mount package design

Oscillators Applications

• General purpose clock generation
• Digital signal processing systems
• Communication equipment timing

Oscillators Procurement Notes

Verify the specific suffix (OE) to confirm the enable/disable feature against the datasheet. Ensure the operating temperature range meets system requirements. Confirm the 1.8V supply voltage compatibility with the target circuit design before procurement.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required. The small 2.0x1.6mm footprint suits space-constrained designs. The enable pin allows for power management strategies in battery-operated devices.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics. The series offers various frequencies in a standardized small outline package. The OE suffix denotes the presence of an output enable control line distinct from standard fixed-output variants.

Oscillators Replacement Considerations

Check for direct substitutes within the same series offering identical 26.9865 MHz frequency and 1.8V operation. Verify pinout compatibility and electrical specifications match exactly before substitution.
