TIMING SPECIFICATIONS
GENERAL NOTES
This data sheet represents production released specifications for
the AD14160L (3.3 V), and the AD14160 (5 V). The ADSP-
21060 die components are 100% tested, and the assembled
AD14160/AD14160L units are again extensively tested at-
speed, and across-temperature. Parametric limits were estab-
lished from the ADSP-21060 characterization followed by
further design/analysis of the AD14160/AD14160L package char-
acteristics. The specifications shown are based on a CLKIN
frequency of 40 MHz (t
specifications at other CLKIN frequencies (within the min-max
range of the t
difference 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.

ESD SENSITIVITY
The AD14160/AD14160L modules are ESD (electrostatic discharge) sensitive devices. Electro-
static charges readily accumulate on the human body and equipment and can discharge without
detection. Permanent damage may occur to devices subjected to high energy electrostatic
discharges.
The ADSP-21060 processors include proprietary ESD protection circuitry to dissipate high
energy discharges. Per method 3015 of MIL-STD-883, the ADSP-21060 processors have been
classified as a Class 2 device.
Proper ESD precautions are recommended to avoid performance degradation or loss of function-
ality. Unused devices must be stored in conductive foam or shunts, and the foam should be
discharged to the destination socket before devices are removed.

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.
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 processor
operates correctly with other devices.

or any other conditions greater than 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.
