Oscillators Procurement Notes

Verify the specific frequency tolerance and phase noise specifications against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout design. Check for any specific reflow soldering profile requirements to maintain component integrity during assembly processes.

Oscillators Selection Notes

Select this component when a precise 47.3337 MHz reference is required for LVCMOS-based circuits. Consider the 1.8V operation and standby feature for battery-powered or energy-efficient designs. Evaluate the thermal performance within the -40°C to 85°C range against environmental conditions. Compare size constraints against alternative packages if board space is limited.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options, typically packaged in small form factors suitable for modern electronics. The 'PD' suffix indicates the presence of a power-down pin for standby functionality.

Oscillators Replacement Considerations

Direct substitutes must match the 47.3337 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify equivalent electrical characteristics such as current consumption and temperature range. Cross-reference with other manufacturers offering similar MEMS or crystal oscillators if availability is an issue.
