5.10.2 Factors Determining I/O Temporal Performance

A number of factors control the exact durations of propagation delays. The influence of some of the
factors is, however, ill constrained or unknown. As a consequence, generally valid and exact
quantitative predictions of propagation delays are impossible.
The following factors apply:
Factors Influencing Camera I/O
Propagation Delays
Operating temperature:
Unknown but temperature must
be within specified range; see
Section 1.11.1 on page 49.
Production spread:
Unknown
Aging (optocouplers):
Unknown
External I/O supply voltage:
Depends on application but must
be within specified ranges; see
Section 5.7 through Section
Load resistance:
Depends on application
Load current:
Depends on application but must
be within specified ranges; see
Section 5.7 through Section
Table 25: Factors Influencing Camera I/O Propagation Delays (
Among the insight that can be gained from
different propagation delays even for cameras that were produced in one batch and that are
operated under identical conditions.
