OUTPUT DRIVE CURRENTS
Figure 37
shows typical I-V characteristics for the output driv-
ers of the ADSP-2136x. The curves represent the current drive
capability of the output drivers as a function of output voltage.
TEST CONDITIONS
The ac signal specifications (timing parameters) appear in
Table 14 on Page 21
through
Table 40 on Page 45
. These include
output disable time, output enable time, and capacitive loading.
The timing specifications for the SHARC apply for the voltage
reference levels in
Figure 38
.
Timing is measured on signals when they cross the 1.5 V level as
described in
Figure 39
. All delays (in nanoseconds) are mea-
sured between the point that the first signal reaches 1.5 V and
the point that the second signal reaches 1.5 V.
CAPACITIVE LOADING
Output delays and holds are based on standard capacitive loads:
30 pF on all pins (see
Figure 38
).
Figure 42
shows graphically
how output delays and holds vary with load capacitance. The
graphs of
Figure 40
,
Figure 41
, and
Figure 42
may not be linear
outside the ranges shown for Typical Output Delay vs. Load
Capacitance and Typical Output Rise Time (20% to 80%,
V = Min) vs. Load Capacitance.
