Oscillators Procurement Notes

Verify the specific ordering suffix to ensure correct frequency tolerance and load capacitance requirements match the target circuit design. Confirm that the 1.8V supply voltage aligns with the system power rails before integration. Ensure the 4-SMD package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 14.29 MHz reference is required for LVCMOS-compatible circuits. Consider the 1.8V operating voltage constraint against available power supplies. Evaluate the need for active enable/disable controls versus continuous operation. Compare physical dimensions against available board space constraints to ensure the 4-SMD form factor fits within the designated area without interference.
