Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct frequency and voltage specifications. Confirm that the OE suffix aligns with the required enable/disable pin configuration. Check the datasheet for absolute maximum ratings and thermal characteristics before integration. Ensure the selected variant matches the target PCB footprint and soldering profile requirements.
Selection Notes
Select this component when a 1.8V supply voltage is available and LVCMOS outputs are required. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the 4-SMD package size for space-constrained layouts. Verify that the 13.02 MHz frequency meets the system clock requirements without additional dividers.
Part Context
This part belongs to the Mercury Electronics XO series, which provides standard frequency generation solutions. The company specializes in quartz crystals and oscillators, offering various packages and frequencies. This specific model represents a low-voltage option within their portfolio, targeting modern portable and embedded applications requiring precise timing signals.
Replacement Considerations
Direct substitutes must match the 13.02 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical parameters such as load capacitance and drive level. Cross-reference with other manufacturers' 1.8V XO offerings in similar footprints if availability is an issue.
