Procurement Notes
Verify the specific frequency tolerance and stability specifications against your system requirements before procurement. Ensure that the 1.8V supply voltage aligns with your target circuit design. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs to prevent signal integrity issues or damage during operation.
Selection Notes
Select this component when a precise 94.697 MHz clock source is required within space-constrained designs. The choice depends on the necessity for low-voltage operation at 1.8V and the requirement for an enable pin to manage power states. Consider the physical footprint of the 4-SMD package relative to available PCB real estate.
Part Context
This part belongs to the Mercury Electronics XO series, which provides standard clock oscillators. The manufacturer specializes in quartz crystals and frequency control products, leveraging decades of experience in the industry. This specific model represents a standard frequency option within their broader portfolio of surface-mount oscillators.
Replacement Considerations
Direct substitutes must match the 94.697 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics before swapping components to ensure seamless integration without redesigning the host circuit board.
