- Includes standby and power-down functionality
- Utilizes LVCMOS output interface
Applications
- Digital signal processing systems
- Communication equipment requiring precise clocking
- Embedded control circuits
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout to guarantee proper soldering and mechanical stability during assembly processes.
Selection Notes
Select this component when a stable 80.37225 MHz reference is required for LVCMOS-compatible digital interfaces. Consider the 1.8V operating voltage constraint and the availability of power-down modes for applications prioritizing energy efficiency. Evaluate the small 2.0x1.6mm form factor against available board space constraints compared to larger oscillator packages.
Part Context
This part belongs to the Mercury Electronics XO series, which provides standard frequency generation solutions. The manufacturer has extensive experience in quartz crystal production. The model designation indicates specific electrical parameters including the 1.8V supply and LVCMOS output type, distinguishing it from other voltage or logic variants within the broader product family.
Replacement Considerations
Direct substitutes include other 80.37225 MHz LVCMOS oscillators in 4-SMD no-lead packages with 1.8V operation. Verify pin compatibility and thermal characteristics when cross-referencing with alternative manufacturers' components to ensure seamless integration without redesigning the host circuit board.
