ers of the ADSP-2126x. 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 16 on Page 18
output disable time, output enable time, and capacitive loading.
Timing is measured on signals when they cross the 1.5 V level as
described in
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
