• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded electronics requiring low-profile oscillators

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 footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical specifications to guarantee operational reliability.

Selection Notes

Select this component when a precise 100.25 MHz clock source is required with low voltage operation. The LVCMOS output ensures direct interfacing with standard digital logic families without additional level shifting. The enable pin allows for power management strategies in battery-operated devices. Consider the small form factor for space-constrained designs.

Part Context

This part belongs to the Mercury Electronics XO series, designed for high-reliability timing applications. The company has decades of experience in quartz crystal manufacturing. This specific model represents a standard frequency option within their portfolio of surface-mount oscillators.

Replacement Considerations

Direct substitutes must match the 100.25 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Verify pinout compatibility and electrical parameters such as phase noise and jitter before substitution.
