Oscillators Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration when placing orders. Confirm that the requested quantity matches the manufacturer's standard reel specifications. Ensure the procurement documentation explicitly references the full part number including the temperature grade and frequency tolerance to avoid substitution errors during assembly.

Oscillators Selection Notes

Select this component for designs requiring precise timing in harsh environments due to its wide operating temperature range. Consider the ±50 ppm stability sufficient for general digital logic but verify against stricter jitter requirements for high-speed serial interfaces. Evaluate the 3.3V supply compatibility with existing system power rails before integration into the schematic design phase.
