Procurement Notes

Verify the specific frequency suffix matches the required 80.3722 MHz specification during procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the LVCMOS output logic is compatible with the receiving interface. Check the 4-SMD no lead package dimensions against the PCB footprint to guarantee mechanical fit and soldering reliability.

Selection Notes

Select this component when a precise 80.3722 MHz reference is required for low-voltage digital systems. The choice depends on the necessity for LVCMOS outputs and the availability of a 1.8V power rail. Consider the enable pin feature if dynamic power control is needed. Evaluate the small form factor against available board space constraints.
