Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against the specific application datasheet before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operating specifications. Confirm that the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official mechanical drawing to prevent assembly errors.

Oscillators Selection Notes

Select this component when a precise 26.996625 MHz reference is required with low voltage operation. Consider the LVCMOS output swing limits relative to the receiving input thresholds. Evaluate the thermal environment to ensure operation within the specified temperature range. Compare package size constraints against alternative oscillators if board real estate is limited.

Oscillators Part Context
