Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational specifications. Confirm that the PCB footprint matches the 2.0x1.6mm SMD no-lead package dimensions to avoid assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a precise 29.97 MHz clock source is required for digital systems operating at 1.8V. Consider the small form factor suitable for space-constrained designs. Evaluate the need for power-down capabilities if energy efficiency is a priority in the application environment compared to continuous operation alternatives.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency oscillators. The 'PD' suffix indicates the inclusion of a power-down control feature. The series typically offers various frequencies within a compact SMD package, catering to modern electronics requiring reliable timing signals in minimal board space.

Oscillators Replacement Considerations

Direct substitutes must match the 29.97 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pin compatibility and electrical characteristics of alternative manufacturers' components to ensure functional equivalence without redesigning the host circuit.
