Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 1.8V supply voltage aligns with the system's power rails. Confirm that the 4-SMD no-lead package dimensions fit within the available PCB real estate. Cross-reference the part number suffix with the manufacturer's documentation to ensure the correct variant is ordered.

Oscillators Selection Notes

Select this model when a low-profile surface-mount oscillator with LVCMOS outputs is required. The 1.8V operating voltage makes it suitable for modern low-power digital logic families. Consider the standby feature if power efficiency during idle states is a critical design constraint. Verify compatibility with the host controller's input thresholds and drive requirements.

Oscillators Part Context
