ESD SENSITIVITY
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADSP-2106x 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.
TIMING SPECIFICATIONS
GENERAL NOTES
The following timing specifications are target specifications and
are based on device simulation only.
The timing specifications shown are based on a CLKIN frequency
of 40 MHz (t
at other CLKIN frequencies (within the min–max range of the
t
ence between the actual CLKIN period and a CLKIN period
of 25 ns:
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 parameters to derive longer times.
See Figure 26 under Test Conditions for voltage reference
levels.

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 de-
vice connected to the processor (such as memory) is satisfied.
Timing Requirements apply to signals that are controlled by
circuitry external to the processor, such as the data input for a
read operation. Timing requirements guarantee that the proces-
sor operates correctly with other devices.
