Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct voltage and output configuration. Confirm that the 'OE' suffix aligns with the required Enable/Disable functionality rather than other variants. Cross-reference the part number with the latest datasheet to validate pinout and electrical specifications before integration into the design.

Oscillators Selection Notes

Select this component when a precise 35.811 MHz timing source is required with low-voltage operation. Ensure the application environment supports the specified 1.8V supply level. Consider the thermal and mechanical constraints of the 4-SMD No Lead package during PCB layout planning. Verify that the LVCMOS output swing matches the input requirements of the downstream load.
