Timing Parameters and Board Routing Analysis
The timing parameter values specified in this data sheet do
not
include delays by board routings. As a good
board design practice, such delays must
always
be taken into account. Timing values may be adjusted by
increasing/decreasing such delays. TI recommends utilizing the available I/O buffer information specification
(IBIS) models to analyze the timing characteristics correctly. To properly use IBIS models to attain accurate
timing analysis for a given system, see the
Using IBIS Models for Timing Analysis
application report (literature
number SPRA839). If needed, external logic hardware such as buffers may be used to compensate any timing
differences.
For inputs, timing is most impacted by the round-trip propagation delay from the DSP to the external device
and from the external device to the DSP. This round-trip delay tends to negatively impact the input setup time
margin, but also tends to improve the input hold time margins (see Table 6
1 and Figure 6
4).
Figure 6
4 represents a general transfer between the DSP and an external device. The figure also represents
board route delays and how they are perceived by the DSP and the external device.
