ADSP-21363
Preliminary Technical Data
Note the definitions of various clock periods that are a function
of CLKIN and the appropriate ratio control (
Table 8
).
Figure 5
shows Core to CLKIN ratios of 6:1, 16:1 and 32:1 with
external oscillator or crystal. Note that more ratios are possible
and can be set through software using the power management
control register (PMCTL). For more information, see the
ADSP-2136x SHARC Processor Programming Reference
.
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, it is
not meaningful to add parameters to derive longer times. See
Figure 30 on page 36
under Test Conditions for voltage refer-
ence levels.
Switching characteristics
specify how the processor changes its
signals. Circuitry external to the processor must be designed for
compatibility with these signal characteristics. Switching char-
acteristics describe what the processor will do in a given
circumstance. 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.
