Oscillators Procurement Notes

Verify the specific ordering suffix and package variant against the official datasheet to ensure compatibility with your design requirements. Confirm that the 1.8V supply voltage aligns with your system's power architecture. Check for RoHS compliance status if required by your manufacturing standards. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints before finalizing procurement decisions.

Oscillators Selection Notes

Select this component when a small form factor is critical for space-constrained designs. Consider the 1.8V operating voltage requirement to ensure it matches your system's power rails. Evaluate the need for a standby feature if power management is a priority. Verify that the LVCMOS output interface is compatible with your receiving logic gates or microcontroller inputs for proper signal integrity.
