ADC to DMUX
Connections
The DMUX inputs configuration has been optimized to be connected to the TS8388B ADC.
The die in the TBGA package is up. For the ADC, different types of packages can be used
such as CBGA with die up or the CQFP68 down. The DMUX device being completely sym-
metrical, both ADC packages can be connected to the TBGA package of the DMUX criss-
crossing the lines (see Table 8).
Note: The connection between the ADC evaluation board and the DMUX evaluation board requires a
4-pin shift to make the D0 pin match either the I7 or I0 pin of the DMUX evaluation board.
