Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 1.8V supply rail is stable and within the operational limits defined in the official datasheet. Confirm that the 4-SMD no-lead package footprint matches the PCB layout specifications to ensure proper soldering and mechanical stability.

Oscillators Selection Notes

Select this component when a 27.115 MHz clock source is required with low voltage operation. The choice is driven by the need for LVCMOS compatibility and space-constrained designs due to the small SMD package. Consider the standby feature if power management is a critical system requirement compared to continuous operation alternatives.

Oscillators Part Context
