Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout constraints. Cross-reference the datasheet for operating temperature ranges to guarantee reliability under expected environmental conditions.

Selection Notes

Select this component when a 50.050 MHz frequency is required within a 1.8V logic environment. Consider the small 2.0x1.6mm form factor for space-constrained designs. Evaluate the need for enable/disable control features for power optimization. Compare performance metrics such as phase noise and stability against alternative oscillators if high-precision timing is critical for the specific application.

Part Context
