• Supports enable/disable functionality for dynamic power control
• Utilizes LVCMOS output logic for digital interface compatibility
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Oscillators Procurement Notes

Verify the specific suffix OE against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm the 4-SMD package dimensions fit within your PCB footprint constraints before finalizing procurement.

Oscillators Selection Notes

Select this component when a 24.66875 MHz reference is required with low voltage operation. The enable pin allows for system-wide power saving during idle states. Consider the LVCMOS output swing levels to ensure compatibility with downstream logic inputs without additional buffering.

Oscillators Part Context

This part belongs to the QHTF series of standard oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 18 prefix typically indicates the 1.8V supply variant, while the 21 series denotes specific performance grades within their standard XO lineup.

Oscillators Replacement Considerations

Check for direct substitutes such as 18QHTF21-24.000000-OE if a different frequency is acceptable. Verify pin-to-pin compatibility with other 4-SMD oscillators from Mercury or third-party vendors offering similar LVCMOS specifications.
