SIGNAL GROUPINGS

The input and output signals of the DSP56367 are organized into functional groups, which are
listed in Table 2-1 and illustrated in Figure 2-1.
The DSP56367 is operated from a 1.8V supply; however, some of the inputs can tolerate
3.3V. A special notice for this feature is added to the signal descriptions of those inputs.
Remember, the DSP56367 offers 150 million instructions per second (MIPS) using an internal
150 MHz clock at 1.8 V and 100 million instructions per second (MIPS) using an internal 100
MHz clock at 1.3.3V.
