4 Signal Groupings

The input and output signals of the DSP56374 are organized into functional groups, which are listed in

Table 3.

The DSP56374 is operated from a 1.25 V and 3.3 V supply; however, some of the inputs can tolerate 5.0 V.

A special notice for this feature is added to the signal descriptions of those inputs.
