Procurement Notes

Verify the specific suffix 'DJ' against the manufacturer's official datasheet to confirm exact pinout configuration, load capacitance requirements, and tolerance specifications. Ensure the selected variant matches the required operating temperature range and supply voltage constraints for the target application environment before finalizing procurement.

Selection Notes

Select this component when a fixed 30MHz clock source is required within a strict 2016 footprint. Consider the ±50ppm stability limit for precision timing needs and verify that the 22mA maximum current consumption aligns with the power budget. Confirm that the CMOS output swing meets the input threshold requirements of the downstream logic devices.

Part Context

This part belongs to the QTM216 series of low-profile CMOS oscillators designed for portable and industrial applications. The series offers various frequency options and stability grades within a standardized 2.0mm x 1.6mm package, allowing designers to maintain consistent board layouts while adjusting electrical specifications for different system requirements.

Replacement Considerations

Direct substitutes must match the 2016 package dimensions, 30MHz frequency, and CMOS output type. Verify pin-to-pin compatibility, particularly regarding the enable function on Pin1. Alternative parts should offer comparable ±50ppm stability and support the 1.8V-3.3V supply range to ensure seamless integration without circuit redesign.
