output has reached a specified high or low trip point, as shown
in the Output Enable/Disable diagram (
Figure 17
). If multiple
pins (such as the data bus) are enabled, the measurement value
is that of the first pin to start driving.
Example System Hold Time Calculation
To determine the data output hold time in a particular system,
first calculate t
DECAY
using the equation at
Output Disable Time
on Page 34
. Choose
V to be the difference between the ADSP-
2192M’s output voltage and the input threshold for the device
requiring the hold time. A typical
V will be 0.4 V. C
L
is the total
bus capacitance (per data line), and I
L
is the total leakage or three-
state current (per data line). The hold time will be t
DECAY
plus the
minimum disable time (i.e., t
DATRWH
for the write cycle).
Capacitive Loading
Output delays and holds are based on standard capacitive loads:
50 pF on all pins. The delay and hold specifications given should
be derated for loads other than the nominal value of 50 pF.
Environmental Conditions
The thermal characteristics in which the DSP is operating
influence performance (see
Table 38
).
