Oscillators Procurement Notes

Verify that the specific part number matches the required frequency tolerance and package dimensions. Confirm RoHS compliance status if environmental regulations are critical to the assembly process. Ensure the supply voltage aligns with the 3.3 VDC specification to prevent operational issues. Cross-reference the manufacturer's latest documentation for any updates to the pinout or electrical characteristics before finalizing procurement.

Oscillators Selection Notes

Select this component when a low-profile, 27 MHz CMOS oscillator is required for 3.3 V systems. Consider the 50 ppm stability requirement against application timing needs. Evaluate the 3.2 mm x 2.5 mm footprint against available PCB space. Compare against other ISM97 variants if different frequencies or package sizes are needed while maintaining similar performance characteristics.
