Oscillators Procurement Notes

Verify the specific suffix 'R' against the manufacturer's current datasheet to confirm exact electrical tolerances and temperature range specifications. Ensure the ordering part number matches the required output load and enable functionality. Cross-reference the package dimensions with the PCB footprint library to guarantee mechanical compatibility during assembly.

Oscillators Selection Notes

Select this component when a standard HCMOS clock source is required at 40 MHz with low-power standby capabilities via the enable pin. Consider the 4-SMD package size for board space constraints. Verify that the operating temperature range meets the environmental requirements of the target application before finalizing the design.
