Definition of the Sij reference planes
CHA3664-QAG
The reference planes are defined from the footprint of the recommended characterization board shown below under the number 96272. The reference is the symmetrical axis of the package. The input and output reference planes are located at 2.65mm offset (input wise and output wise respec.) from this axis. Then, the given Sij incorporates this land pattern.
