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 rail is stable within the operational specifications. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent soldering defects. Cross-reference the datasheet for operating temperature range compliance.

Oscillators Selection Notes

Select this component when a precise 41.01 MHz reference is required for LVCMOS-compatible logic families. Consider the 1.8V operating voltage constraint and the necessity for a power-down feature. Evaluate the small form factor against available board space. Compare performance metrics such as phase noise and stability if high-precision timing is critical for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies within a standardized 2.0x1.6mm package. The 'PD' suffix indicates the inclusion of a power-down pin or function. This family is designed for applications demanding low profile and efficient power usage in portable devices.

Oscillators Replacement Considerations

Direct substitutes must match the 41.01 MHz frequency, LVCMOS output, 1.8V supply, and 2.0x1.6mm package. Verify pinout compatibility for the power-down function. Check equivalent electrical parameters such as current consumption and startup time.
