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 power management architecture. Ensure the 4-SMD footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable feature allows for power management strategies in battery-operated devices. Consider the small form factor for space-constrained designs where standard leaded packages cannot fit within the available board area.
Part Context
This part belongs to the Mercury Electronics XO series, which provides standard oscillators for various digital applications. The manufacturer has extensive experience in quartz products, ensuring consistent quality in frequency control components. This specific model represents a common configuration for modern low-power electronic systems.
Replacement Considerations
Direct substitutes must match the 67.125 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications before swapping. Consult official cross-reference lists from Mercury Electronics or authorized distributors for validated alternative part numbers.
