Procurement Notes
Verify the specific part number against official Mercury Electronics documentation to confirm electrical parameters and pinout compatibility. Ensure that the 1.8V supply requirement aligns with the target circuit design. Confirm that the LVCMOS output levels are suitable for the receiving logic family. Cross-reference the package dimensions with the PCB footprint to ensure mechanical fit.
Selection Notes
Select this component when a precise 10.00135 MHz reference is required in space-constrained applications. The 1.8V operating voltage makes it suitable for low-power portable devices. The enable feature allows for power management strategies. Verify that the LVCMOS output swing meets the input requirements of downstream components before finalizing the design.
Part Context
This oscillator belongs to the Mercury Electronics SMD oscillator series, designed for high-frequency stability in small form factors. The company specializes in quartz crystal products, leveraging decades of experience in frequency control manufacturing. This specific model represents a standard solution for general-purpose timing needs.
Replacement Considerations
Consult official Mercury Electronics substitution guides for compatible alternatives. Ensure any replacement matches the 10.00135 MHz frequency, 1.8V supply, and LVCMOS output type. Verify package compatibility with the existing 4-SMD footprint.
