Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply voltage aligns with your power architecture. Ensure the 4-SMD package footprint matches your PCB layout constraints. Cross-reference the part number suffix with official documentation to confirm exact specifications.

Selection Notes

Select this component when a precise 75.535 MHz timing source is required within a 1.8V logic environment. Consider the enable/disable feature if power management during idle states is necessary. Evaluate the small form factor against available board space. Compare performance against other Mercury oscillators if different frequencies or voltages are needed.

Part Context

This oscillator belongs to the Mercury Electronics series of quartz-based timing components. The company specializes in frequency control products including crystals and oscillators. This specific model represents a standard XO variant designed for general-purpose digital applications requiring stable clock signals.

Replacement Considerations

Direct substitutes must match the 75.535 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics before swapping. Consult manufacturer cross-reference lists for approved alternatives.
