Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly issues. Check for any specific environmental certifications required by the end product regulations.

Oscillators Selection Notes

Select this component when a stable 26.806 MHz clock source is required for low-voltage digital circuits. Consider the LVCMOS output type for direct interfacing with standard logic families. Evaluate the need for enable/disable functionality if power management during idle states is critical. Compare package size constraints against available board space to ensure the 4-SMD form factor fits the design layout.
