The component is designed for surface mount applications and typically exhibits a frequency stability of ±50ppm over the operating temperature range of -40°C to 85°C.

Oscillators Feature Summary

• Compact 4-SMD no-lead surface mount package
• LVCMOS output logic compatibility
• Integrated enable and disable control function
• Standard frequency tolerance specification

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Consumer electronics circuit boards
• Industrial control modules requiring standard oscillators

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 24.998125 MHz target. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the LVCMOS output type is compatible with the receiving logic inputs. Check the operating temperature range requirements against the specified -40°C to 85°C limit. Validate the physical footprint against the 2.0x1.6mm SMD package dimensions during layout review.

Oscillators Selection Notes

Select this component when a low-profile surface mount oscillator is required for space-constrained designs. The 1.8V operation makes it suitable for modern low-voltage digital systems. The enable/disable feature allows for dynamic power management strategies. Consider the standard frequency stability if high precision is not critical. The small form factor aids in dense PCB layouts compared to larger through-hole or standard SMD packages.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature crystal oscillators. The series utilizes quartz resonator technology to provide stable timing signals. The 'OE' suffix typically denotes a specific ordering or packaging variant within the manufacturer's catalog. These components are widely used in applications requiring reliable clock sources without the complexity of TCXO or VCXO technologies.

Oscillators Replacement Considerations

Direct substitutes must match the 24.998125 MHz frequency, 1.8V supply, and LVCMOS output. Verify pinout compatibility for the 4-SMD no-lead package. Ensure equivalent frequency stability and temperature range specifications. Cross-reference with other manufacturers offering similar miniature XO devices if Mercury stock is unavailable.
