Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against the specific application design before procurement. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions. Check for RoHS compliance status if required by project specifications. Validate the enable/disable pin configuration with the host controller circuitry.

Oscillators Selection Notes

Select this component when a low-profile oscillator with enable control is required for 1.8V systems. Consider the 22.8 MHz frequency specifically for applications needing this exact clock rate. Evaluate the LVCMOS output swing against the input thresholds of downstream logic. Compare the physical size constraints against alternative packages if space is limited. Assess power management needs where the enable feature provides significant energy savings.
