A distinction should be made between the amount of used output channels and the amount of

active output channels. The amount of used output channels refers to the amount of channels

that is used for full horizontal ROI readout. The amount of active output channels refers to the

amount of channels that are actively outputting pixel data. Depending on the horizontal ROI

settings, the amount of active channels is either equal to or less than the amount of used

output channels. More information on configuring the horizontal ROI can be found in section

7.5.4.

Typically, all of the sensor’s output channels are used. The amount of used channels may be

reduced for the following reasons:

●

Power saving. By limiting the number of used output channels, all unused output

channels are automatically powered down.

●

The receiving system is IO-limited and cannot capture all output channels at once.

The amount of used output channels is set with the MAX_NR_OUTP register as shown in

Figure 77.
