Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure accuracy. Confirm that the OE suffix corresponds to the intended enable/disable configuration and voltage level. Cross-reference the part number with official Mercury Electronics catalogs to validate availability and technical specifications before finalizing procurement orders.

Selection Notes

Select this component when a fixed 80.6 MHz frequency is required with low-voltage operation. Ensure the system design accommodates the 1.8V supply requirement and LVCMOS logic levels. Verify that the 4-SMD footprint aligns with the PCB layout constraints and that the enable pin can be properly managed by the host controller.

Part Context

This model belongs to the Mercury Electronics XO series, which provides stable frequency references for electronic circuits. The product line focuses on quartz-based oscillators offering various frequencies and packages. This specific variant targets applications needing reliable timing without the complexity of programmable devices.

Replacement Considerations

Direct substitutes include other 80.6 MHz LVCMOS oscillators in similar packages from compatible manufacturers. Verify electrical parameters such as load capacitance and drive strength. Check if alternative parts support the same enable/disable mechanism and voltage range to ensure functional equivalence.
