Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application's specifications before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6 mm package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 32.4864 MHz timing source is required for LVCMOS-compatible interfaces. Consider the 1.8V operating voltage constraint and the need for active standby functionality. Evaluate the small form factor suitability for space-constrained designs compared to larger through-hole or standard SMD oscillator packages.

Oscillators Part Context
