OUTPUT DRIVE CURRENTS
Figure 19 shows typical I-V characteristics for the output drivers
of the ADSP-2183. The curves represent the current drive
capability of the output drivers as a function of output voltage.

POWER DISSIPATION
To determine total power dissipation in a specific application,
the following equation should be applied for each output:
C

V
DD
2
×
f
C
= load capacitance,
f
= output switching frequency.
Example:
In an application where external data memory is used and no
other outputs are active, power dissipation is calculated as
follows:
Assumptions:
External data memory is accessed every cycle with 50% of the
address pins switching.
External data memory writes occur every other cycle with
50% of the data pins switching.
Each address and data pin has a 10 pF total load at the pin.
The application operates at V
DD
= 3.3 V and t
CK
= 30.0 ns.
