Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target circuit's power rails. Ensure the 4-SMD footprint matches your PCB land pattern specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 35.7 MHz reference is required alongside strict power constraints. The LVCMOS output ensures compatibility with standard digital logic families without additional buffering. Consider the physical dimensions and leadless package type if board real estate is limited. Validate that the standby feature meets your system's sleep current requirements.
