Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this component when a precise 47.999 MHz clock source is required for low-voltage digital systems. The choice depends on the necessity for LVCMOS signaling levels and the availability of an enable pin for dynamic power control. Consider the physical constraints of the 4-SMD package size relative to the available board space.
