Procurement Notes
Verify the specific part number suffix to ensure compatibility with required voltage levels and output logic types. Confirm that the operating temperature range meets the environmental requirements of the target application. Cross-reference the package dimensions against the PCB footprint to ensure proper mechanical fit during assembly.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The small form factor makes it suitable for space-constrained designs. Ensure the system design accounts for the standby control feature if power efficiency is a priority. Validate that the frequency stability specifications align with the clocking requirements of the connected integrated circuits.
