Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly errors during manufacturing.

Selection Notes

Select this model when a precise 80.7 MHz clock signal is required with low-power LVCMOS compatibility. Consider the enable/disable feature if power management or clock gating is necessary within the design. Evaluate the small form factor against available board space constraints to ensure mechanical fitment.
