Procurement Notes
Verify the specific part number suffix to ensure compatibility with required voltage levels and enable/disable functions. Confirm that the 1.8V supply requirement aligns with the target system design. Ensure the 4-SMD package dimensions fit within the allocated PCB footprint. Cross-reference the manufacturer datasheet for detailed electrical characteristics before integration.
Selection Notes
Select this component when a stable 58.9824 MHz clock source is required for low-voltage digital circuits. The LVCMOS output ensures compatibility with standard logic families. Consider the power-down feature if energy efficiency during idle states is a priority. Verify that the operating temperature range meets the environmental requirements of the final application.
Part Context
This model belongs to the Mercury Electronics XO series, which provides standard frequency generation solutions. The 18QHTF21 prefix indicates a specific form factor and performance class within their catalog. These oscillators are engineered for reliability in consumer and industrial electronics, offering consistent frequency stability across specified conditions.
Replacement Considerations
Direct substitutes must match the 58.9824 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check for equivalent power-down functionality. Verify pinout compatibility to ensure seamless board replacement without redesign.
