Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply rail is stable and within the operational limits specified in the official datasheet to ensure reliable oscillator performance.

Oscillators Selection Notes

Select this component when a precise 16.385228 MHz reference is required in space-constrained designs. The small 2.0x1.6mm footprint makes it suitable for high-density PCB layouts. Ensure the application supports LVCMOS logic levels and can accommodate the 1.8V operating voltage.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in frequency control products. The series offers various frequencies in a standardized small SMD package. The 'PD' suffix indicates the inclusion of power-down capabilities, distinguishing it from standard continuous-operation oscillators within the same form factor.

Oscillators Replacement Considerations

Direct replacements must match the 16.385228 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify pin compatibility and electrical specifications with alternative manufacturers offering similar surface-mount oscillators.
