18QHTF21-26.667-OE

Oscillators Overview

The 18QHTF21-26.667-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 26.667 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an Enable/Disable function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component supports a standby mode and is designed for applications requiring precise timing signals within a small form factor.

Oscillators Feature Summary

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

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Portable electronic devices requiring low power consumption

Oscillators Procurement Notes

Verify the specific suffix 'OE' to confirm the presence of the enable/disable control feature, as this distinguishes it from variants without control pins. Ensure the supply voltage requirement of 1.8V aligns with the target circuit design. Confirm the package type matches the PCB footprint specifications before ordering. Cross-reference the manufacturer part number with official distributor catalogs to ensure authenticity and correct revision status.

Oscillators Selection Notes

Select this component when a 26.667 MHz clock source is required with low voltage operation. The enable/disable functionality makes it suitable for battery-powered systems where power conservation is critical. Consider the 1.8V supply constraint and LVCMOS output swing when interfacing with downstream logic circuits. The small 2.0x1.6mm package is ideal for space-constrained designs compared to larger oscillator footprints.

Oscillators Part Context

This oscillator belongs to the QHTF series from Mercury Electronics, which focuses on high-frequency quartz-based timing solutions. The series typically offers various frequencies and package sizes to meet diverse electronic design requirements. Mercury Electronics specializes in frequency control products including crystals, oscillators, and filters, providing reliable timing components for industrial and consumer electronics markets.

Oscillators Replacement Considerations

Direct replacements must match the 26.667 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify that substitute parts include the enable/disable control feature if power management is required. Check dimensional tolerances to ensure mechanical compatibility with the existing PCB layout.
