Line Addressing
The sensor operates line wise: a line of pixels can be
selected and reset, and a line of pixels can be selected for
readout into the column amplifier structures. There is no
frame reset operation, there is no frame transfer.
Image acquisition is done by sequencing over all lines of
interest and applying the required reset and/or readout
control to each line selected.
YRD ? YRST
The sensor array contains two vertical shift registers for
line addressing. These registers are one-hot; they contain a
pattern such as ‘00001000000’, at each time pointing to one
line of pixels.

In double sampling and destructive readout, one of these
registers is typically dedicated to addressing the lines to
read, and the other is used for addressing the lines to reset as
part of the electronic shutter operation.
In correlated double sampling and nondestructive
readout, you can choose if one or both shift registers will be
used.
Both Y shift registers can be initialized to a position
indicated by an on-chip address register. This address
register is written by the user through the parallel sensor
programming interface. With this programmable initial
position windowed readout (region-of-interest) is possible.
Both registers can be advanced one position at a time
under user control.
Pixel Addressing
Pixels are read from left to right, generating a
pixel-sequential output signal for each line. The pixel
addressing is similar to the line addressing.
Close to the column amplifiers resides a horizontal shift
one-hot; it contains a pattern such as ‘00001000000’, at a
time pointing to exactly one pixel and one column amplifier.
Line acquisition is done by sequencing over all pixels of
interest and applying each time the required pixel readout
and ADC control signals.
The X shift register can be initialized to a position
indicated by an on-chip address register. This address
register is written by the user through the parallel sensor
programming interface. With this programmable initial
position windowed readout (region-of-interest) is possible.
The X register can be advanced one position under user
control. This requires a pixel clock signal at twice the
frequency of the desired pixel rate.
Column Amplifiers
At the bottom of each column of pixels sits one column
amplifier, for sampling the addressed pixel’s signal and reset
levels. These signals are then locally hold until that
particular pixel is sent to the output channel, in this case
PGA, multiplexer, buffer, and ADC.
