Pin Diagram and Definitions (UTOPIA-to-UTOPIA
Configuration)
Figure 2-3
UTOPIA mode. It is a single CMOS integrated circuit packaged in a 256-pin BGA.
All unused input pins should be connected to ground or power. Unused outputs should
be left unconnected.
Figure 2-2
UTOPIA-to-UTOPIA mode. In this case, the Cell Delineation and the interface to the
framers is performed by RS8228's. The framers could be T1/E1 or DSL. Further
details can be found in the Mindspeed reference designs available online.
