Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.00mm x 1.60mm package dimensions to guarantee proper soldering and mechanical stability during assembly processes.
Selection Notes
Select this component when a precise 11.527848 MHz clock source is required for LVCMOS-compatible digital systems. Consider the small form factor for space-constrained designs. Evaluate the enable/disable feature if power management strategies are necessary for the application. Verify operating temperature ranges meet environmental specifications.
Part Context
This part belongs to the Mercury Electronics Ind. Co. Ltd XO (Standard) series. The manufacturer specializes in quartz crystals and timing components. This specific model represents a standard frequency oscillator designed for general-purpose digital applications requiring stable clock signals in compact packages.
Replacement Considerations
Direct substitutes must match the 11.527848 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and electrical characteristics. Consult official distributor databases for cross-reference lists provided by Mercury Electronics.
