Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the enable/disable pin configuration matches your control logic. Check the operating temperature range to ensure reliability under your environmental conditions. Validate the package dimensions for PCB footprint compatibility.

Selection Notes

Select this component when an 84 MHz LVCMOS clock source is required. Consider the 1.8V operating voltage for low-power applications. Evaluate the enable/disable feature if power saving modes are necessary. Compare the 4-SMD package size against available board space. Assess the need for standard XO performance versus higher precision alternatives like TCXOs.
