Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a stable 74.13 MHz clock source is needed with low power consumption capabilities. The enable feature allows for dynamic power management in battery-operated devices. Consider the small form factor for space-constrained designs. Verify that LVCMOS output levels are compatible with the receiving logic inputs of your target application.
