Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. 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 OE suffix with manufacturer documentation to confirm any specific packaging or testing variations.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS compatibility. The enable/disable feature allows for power management in battery-operated devices. Consider the small form factor of the 4-SMD package for space-constrained designs. Validate that the 54.79125 MHz frequency meets the exact timing needs of the target application.

Oscillators Part Context

This part belongs to the Mercury Electronics series of surface-mount crystal oscillators. The model number indicates a specific frequency variant within their standard XO lineup. Mercury Electronics specializes in quartz-based frequency control products, including crystals, filters, and various oscillator types like TCXO and VCTCXO.

Oscillators Replacement Considerations

Direct substitutes include other 54.79125 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify pinout compatibility and electrical specifications such as current consumption and startup time. Alternative frequencies may require circuit redesign.
