Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD footprint matches the PCB layout design to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a standard LVCMOS oscillator is required at 80.04 MHz with low-power standby capabilities. The choice is driven by the need for a small form factor suitable for dense circuit boards. Consider the operating temperature range and supply voltage compatibility with the host processor or FPGA to ensure reliable operation under all conditions.
