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-21060C/ADSP-21060LC features proprietary ESD pro-
tection 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
Two speed grades of the ADSP-21060C are offered, 40 MHz
and 33.3 MHz. The specifications shown are based on a
CLKIN frequency of 40 MHz (t_CK = 25 ns). The DT derating
allows specifications at other CLKIN frequencies (within the
min–max range of the t_CK specification; see Clock Input below).
DT is the difference between the actual CLKIN period and a
CLKIN period of 25 ns:
DT = t_CK – 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 28 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
switching 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 proces-
sor operates correctly with other devices.
