Table 14. Advantages and Disadvantages of Non-Destructive Readout
Sequencer
The sequencer generates the complete internal timing of the
pixel array and the readout. The timing can be controlled by
the user through the SPI register settings. The sequencer
Table 15. Internal Registers
Low noise - as it is true CDS.
High sensitivity - as the conversion capacitance is kept rather
low.
High dynamic range - as the results includes signal for short and
long integrations times.

Name
System memory required to record the reset level and the inter-
mediate samples.
Requires multiples readings of each pixel, thus higher data
throughput.
Requires system level digital calculations.
operates on the same clock as the ADCs. This is a division by
4 of the input clock.
Table 15 shows a list of the internal registers with a short
description. In the next section, the registers are explained in
more detail.
