Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package size fits within your PCB layout constraints. Cross-reference the manufacturer's datasheet for absolute maximum ratings to prevent operational damage during integration.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is required for the oscillator circuit. The LVCMOS output is appropriate for direct interfacing with standard digital logic families without additional level shifting. Consider the small 2.0x1.6 mm package if space constraints are critical. Verify that the enable pin functionality meets your power management strategy for the target application.

Oscillators Part Context
