to-Serial 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.

Delineation is performed internally and the CX2822x interfaces directly to the
framers. These framers could be T1/E1 or DSL. Further details can be found in the
Mindspeed reference design available online. Configuration information is shown in
