Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 4.915 MHz specification. Confirm the 1.8V operating voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout requirements. Check for any specific quality or reliability certifications if applicable to the end application.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the small form factor of the 4-SMD package for space-constrained layouts compared to larger through-hole alternatives.
