Procurement Notes
Verify the specific ordering suffix OE against the manufacturer's current datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the 1.8V supply requirement aligns with the target system's voltage rails. Check for any recent revisions to the mechanical drawing regarding the 4-SMD no-lead footprint dimensions to ensure PCB layout compatibility.
Selection Notes
Select this component when a 12.123 MHz frequency is required alongside strict size constraints due to its 2.0x1.6 mm footprint. The integrated enable function makes it suitable for battery-powered devices where power conservation during idle states is critical. Ensure the LVCMOS output swing matches the input requirements of the downstream logic circuitry.
