Which part is G3 certifiable, the MAX79356 or the MAX2992?
The MAX2992 is G3 interoperable only in CENELEC-A band. However, it is not certified as there are modes in G3 certification (like coherent modulation) that it cannot support. For ARIB and FCC band, MAX2992 is not standard G3 interoperable. The reason is that the standard evolved during the years the MAX2992 was developed (and beyond) and the MAX2992 cannot support all the features of the standard.
If a customer wants a G3 certifiable product, please use the MAX79356.
