Procurement Notes

Verify the exact datasheet specifications directly from the manufacturer before procurement. Confirm that the 1.8V supply voltage and LVCMOS output levels match your system requirements. Ensure the 4-SMD no-lead footprint aligns with your PCB layout design. Check for any specific handling or storage conditions required for quartz components.

Selection Notes

Select this component when a precise 75.675 MHz reference is needed with low power consumption. The enable/disable feature makes it suitable for battery-operated devices. Ensure the operating temperature range meets your environmental constraints. Verify that the LVCMOS output swing is compatible with downstream logic inputs.

Part Context

This part belongs to Mercury Electronic's standard XO series, which offers various frequencies and voltage options. The 'OE' suffix typically indicates a specific ordering or packaging variant. Mercury Electronic specializes in frequency control products including crystals, oscillators, and filters, providing reliable timing solutions for industrial and consumer markets.

Replacement Considerations

Direct substitutes must match the 75.675 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify electrical parameters such as load capacitance and phase noise if critical. Cross-reference with other manufacturers offering similar small-form-factor oscillators with enable functions.
