OUTPUT DRIVE CURRENTS
Figure 29 shows typical I-V characteristics for the output
drivers of the ADSP-2106x. The curves represent the current
drive capability of the output drivers as a function of output
voltage.

POWER DISSIPATION
Total power dissipation has two components, one due to
internal circuitry and one due to the switching of external
output drivers. Internal power dissipation is dependent on the
instruction execution sequence and the data operands involved.
Internal power dissipation is calculated as follows:
PINT = IDDIN × VDD
The external component of total power dissipation is caused by
the switching of output pins. Its magnitude depends on the
following:
Number of output pins that switch during each cycle (O)
Maximum frequency at which they can switch (f)
Load capacitance (C)
Voltage swing (V
DD
)
and is calculated by
PEXT = O × C × VDD2 × f
