Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications. Check the operating temperature range suitability for the intended environmental conditions. Cross-reference the part number suffix to ensure correct packaging and variant selection.

Oscillators Selection Notes

Select this component when a low-power, small-footprint oscillator is required for 2.22 MHz applications. Consider the LVCMOS output interface for direct digital logic integration. Evaluate the ±50ppm stability requirement against system jitter budgets. Assess the thermal performance within the specified -40°C to +85°C range. Compare alternative frequencies if the exact 2.22 MHz value is not strictly necessary.

Oscillators Part Context

This model belongs to the Mercury Electronic 18QHTF series of standard crystal oscillators. The series offers various frequency options with consistent LVCMOS outputs and enable/disable features. These components are designed for applications requiring precise timing in space-constrained environments. The manufacturer specializes in quartz-based frequency control products with extensive industry experience.

Oscillators Replacement Considerations

Direct substitutes include other 2.22 MHz LVCMOS oscillators with identical 4-SMD packages and 1.8V operation. Verify pinout compatibility and electrical parameters such as current consumption and startup time. Ensure the replacement meets the same ±50ppm stability and temperature range specifications.
