- Embedded device synchronization
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 4-SMD footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.
Selection Notes
Select this oscillator when a stable 65.488 MHz reference is required with low-profile surface mounting. Consider the LVCMOS output swing limits for your receiving logic levels. Evaluate the thermal performance within the specified operating temperature range to ensure long-term reliability in your specific environmental conditions.
Part Context
This model belongs to Mercury Electronics' line of quartz-based frequency control products, which includes crystals, oscillators, and filters. As a pioneer in the Taiwan quartz industry, Mercury provides standardized components like this XO for consistent timing needs across various consumer and industrial electronics sectors.
Replacement Considerations
Direct substitutes must match the 65.488 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications from alternative manufacturers to ensure seamless integration without redesigning the host circuit board.
