Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output compatibility matches the receiving logic inputs. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a precise 30.2438 MHz clock source is needed in a minimal footprint. Consider the 1.8V supply constraint and LVCMOS interface compatibility. The wide temperature range makes it suitable for harsh environments. Evaluate the standby feature benefits for battery-powered or energy-efficient designs compared to non-stby variants.

Oscillators Part Context

This part belongs to the 18QHTF21 series of MEMS oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The 'PD' suffix indicates the inclusion of a power-down pin. These components are designed as direct replacements for traditional quartz crystals in modern high-density PCB layouts.

Oscillators Replacement Considerations

Direct substitutes must match the 30.2438 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify equivalent temperature ranges and standby functionality. Cross-reference pinouts to ensure compatibility with existing board layouts.
