• Integrated enable/disable control functionality
• Low voltage operation at 1.8V
• Compact 4-SMD no lead surface mount package

Oscillators Applications

• General purpose timing circuits
• Embedded systems clock sources
• Consumer electronics timing references
• Industrial control system clocks

Oscillators Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the enable/disable feature and voltage specifications. Ensure the 4-SMD footprint matches the target PCB design. Cross-reference the part number with authorized distributors to confirm availability and authenticity, as generic listings may not reflect the exact electrical characteristics or package type defined in the manufacturer's datasheet.

Oscillators Selection Notes

Select this component when a low-profile, surface-mount oscillator is required for 1.8V logic systems. The LVCMOS output is appropriate for direct interfacing with microcontrollers or FPGAs without additional level shifting. Consider the enable pin requirement if power management is critical. Verify that the 24 MHz frequency aligns with the system clock requirements and that the thermal performance of the SMD package meets the operating environment constraints.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF series of standard crystal oscillators. The series offers various frequencies and packages. The '18' prefix typically indicates the 1.8V supply voltage capability. The 'QHTF' designation relates to the specific package style and performance class within the manufacturer's portfolio. This model represents a standard XO variant rather than a temperature-compensated (TCXO) or voltage-controlled (VCXO) version.

Oscillators Replacement Considerations

Compatible substitutes include other 24 MHz LVCMOS oscillators in 4-SMD packages from manufacturers like Epson, NDK, or SiTime. Ensure the replacement supports 1.8V operation and has similar load capacitance requirements. Verify that the substitute part also includes an enable/disable pin if power control is necessary. Check mechanical dimensions to ensure fit within the existing PCB layout.
