TIMING PARAMETERS
GENERAL NOTES
Use the exact timing information given. Do not attempt to
derive parameters from the addition or subtraction of others.
While addition or subtraction would yield meaningful results for
an individual device, the values given in this data sheet reflect
statistical variations and worst cases. Consequently, you cannot
meaningfully add up parameters to derive longer times.
TIMING NOTES
Switching Characteristics
specify how the processor changes its
signals. You have no control over this timing—circuitry external
to the processor must be designed for compatibility with these
signal characteristics. Switching characteristics tell you what the
processor will do in a given circumstance. You can also use switch-
ing characteristics to ensure that any timing requirement of a
device connected to the processor (such as memory) is satisfied.
Timing Requirements
apply to signals that are controlled by cir-
cuitry external to the processor, such as the data input for a read
operation. Timing requirements guarantee that the processor
operates correctly with other devices.

FREQUENCY DEPENDENCY FOR TIMING
SPECIFICATIONS
t
CK
is defined as 0.5t
CKI
. The ADSP-2183 uses an input clock
with a frequency equal to half the instruction rate: a 16.67 MHz
input clock (which is equivalent to 60 ns) yields a 30 ns proces-
sor cycle (equivalent to 33 MHz). t
CK
values within the range of
0.5t
CKI
period should be substituted for all relevant timing pa-
rameters to obtain the specification value.
Example: t
CKH
= 0.5t
CK
– 7 ns = 0.5 (34.7 ns) – 7 ns = 10.35 ns

*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. These are stress ratings only; functional operation of
the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
ESD SENSITIVITY
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADSP-2183 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
WARNING!
