Signal Path Gain
Analog Gain Stages
Referring to Table 23, several gain settings are available
in the analog data path to apply gain to the analog signal
before it is digitized.
The moment a gain reconfiguration is applied and
becomes valid can be controlled by the gain_lat_comp
configuration.
With ‘gain_lat_comp’ set to ‘0’, the new gain
configurations are applied from the very next frame.
With ‘gain_lat_comp’ set to ‘1’, the new gain settings are
postponed by one extra frame. This feature is useful when
exposure time and gain are reconfigured together, as an
exposure time update always has one frame latency.

NOTE: The sensor performance specifications are tested at unity
gain. Analog gain above 2x affects noise performance.
All other gain settings shown in this table are tested for
sensor functionality.
Digital Gain Stage
The digital gain stage allows fine gain adjustments on the
digitized samples. The gain configuration is an absolute 5.7
unsigned number (5 digits before and 7 digits after the
decimal point).
