Oscillators Procurement Notes

Verify the specific ordering suffix to confirm the exact frequency tolerance and temperature range specifications required for your application. Ensure that the procurement channel provides original manufacturer documentation to validate authenticity. Confirm that the supplied components match the SMD3225 package dimensions for proper PCB footprint compatibility. Check for RoHS compliance status if environmental regulations apply to your production process.

Oscillators Selection Notes

Select this component when a stable 12.288 MHz clock source is needed for audio or low-speed data synchronization tasks. The ±20ppm total frequency stability is sufficient for general industrial and consumer electronics but may not meet high-precision requirements demanding TCXO performance. Consider the 3.3V supply constraint and ensure the host system can provide adequate current without exceeding the 10mA limit. Evaluate the SMD3225 footprint against available board space.
