It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable control capability
• Surface-mount design with no lead construction

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints to guarantee proper assembly and electrical connection.

Selection Notes

Select this component when a stable 112.64 MHz reference is required for LVCMOS-compatible circuits. Consider the enable feature if power efficiency during idle states is critical. Evaluate the operating temperature range to ensure reliability under your specific environmental conditions compared to alternative oscillator models.

Part Context

This part belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronics. The series typically offers various frequencies within a small form factor. This specific model provides the 112.64 MHz variant, distinguishing it from other frequencies like 8.64 MHz or 44.2 MHz in the same package family.

Replacement Considerations

Direct substitutes must match the 112.64 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Verify pinout compatibility and electrical specifications before swapping with generic equivalents to maintain system timing integrity.
