The device requires a 1.8V supply voltage and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications.

Feature Summary

• LVCMOS output logic interface
• Integrated enable and disable control
• Surface-mount 4-SMD no lead package

Applications

• General clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a precise 10.0503 MHz clock source is required with low-voltage operation. The LVCMOS output ensures compatibility with standard digital logic families. Consider the enable/disable feature if power conservation or dynamic clock gating is necessary within the application design constraints.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltages, expanding beyond traditional leaded packages to modern SMD formats. This specific model represents a standard XO variant optimized for compact electronic designs requiring reliable timing signals.

Replacement Considerations

Direct substitutes must match the 10.0503 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter before substitution.
