Procurement Notes

Verify the specific suffix (OE vs PD) against your bill of materials, as it may indicate different packaging or testing standards. Confirm the exact frequency tolerance and load capacitance requirements with the manufacturer's datasheet before integration. Ensure the supply voltage matches the device specifications to avoid performance issues. Check for RoHS compliance status if required by your assembly process.

Selection Notes

Select this component when a precise 73.816666 MHz clock signal is required in a low-profile surface-mount form factor. Consider the LVCMOS output level compatibility with your target logic family. Evaluate the enable/disable feature necessity for power-sensitive designs. Verify that the operating temperature range meets your environmental constraints. Compare size constraints against alternative packages if space is limited.
