Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target system design before procurement. Confirm that the 1.8V supply voltage aligns with the available power rails in the application circuit. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions specified in the official datasheet to guarantee proper solder joint formation and mechanical stability.

Oscillators Selection Notes

Select this component when a stable 47.5 MHz reference is required with minimal power consumption. The LVCMOS output ensures direct interfacing with standard logic families without additional buffering. Consider the operating temperature range limitations defined in the datasheet to ensure reliability under environmental stress conditions typical of the intended deployment scenario.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, which focuses on low-voltage crystal oscillators. The series typically offers various frequency options within a standardized small form factor. The 'PD' suffix indicates the inclusion of power-down functionality, distinguishing it from continuous-operation variants within the same product line.

Oscillators Replacement Considerations

Direct substitutes must match the 47.5 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering equivalent low-profile oscillators if Mercury Electronics inventory is unavailable.
