Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application circuit before procurement. Confirm that the 3.3V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 5.0x3.2mm SMD package dimensions to prevent assembly issues. Cross-reference the datasheet for thermal management requirements during operation.

Oscillators Selection Notes

Select this component when a precise 47.998 MHz clock source is required with low-power LVCMOS outputs. Consider the 3.3V operating voltage constraint and the need for software-controllable enable/disable states. Evaluate the physical space constraints against the 5.0x3.2mm package size. Verify that the frequency stability meets the system timing accuracy needs compared to other available frequencies in the series.
