Table 19 ALC Min Gain Values
Note that if the ALC gain setting strays outside the ALC operating range, either by starting the ALC
outside of the range or changing the ALCMAX or ALCMIN settings during operation, the ALC will
immediately adjust the gain to return to the ALC operating range. It is recommended that the ALC
starting gain is set between the ALCMAX and ALCMIN limits.
ALC HOLD TIME (NORMAL MODE ONLY)
In Normal mode, the ALC has an adjustable hold time which sets a time delay before the ALC begins
its decay phase (gain increasing). The hold time is set by the ALCHLD register.
Table 20 ALC Hold Time
If the hold time is exceeded this indicates that the signal has reached a new average level and the
ALC will increase the gain to adjust for that new average level. If the signal goes above the threshold
during the hold period, the hold phase is abandoned and the ALC returns to normal operation.
