Reduced ROT Readout Mode
When a row is selected, each pixel sees a large capacitive
load.
This comes from two sections - 1) metal line connecting
the pixel output to the column amplifier and parasitic caps
of the 1695 pixels connected to it. 2) The column amplifier
current source transistors. In normal ROT mode, both the
structures are on and to transfer the charge from the pixel to
the column amplifiers, each column amplifier must draw a
larger current.
In the reduced ROT mode, the column amplifier current
source is turned off/disabled. The capacitance of the column
itself acts like the sampling capacitor and the capacitance
seen by the pixel is reduced. As a result, the transfer of the
charge is faster and a reduced ROT can be used. In reduced
ROT mode, the dynamic range of the pixel is lesser than in
normal ROT mode but the power consumption is also
reduced.
The sensor operates in reduced ROT by default, with a
FOT Pin
The actual FOT goes from the falling edge of the internal
VMEM signal to the rising edge of the first internal CLK_Y.
After this rising edge of CLK_Y, the first ROT starts. The
FOT pin goes high at the same moment VMEM goes low
and remains high until one sensor clock period (CLKIN/4)
before the end of the actual FOT. This is shown in Figure 31.
ROT Pin
The actual ROT goes from the rising edge of the internal
CLK_Y signal to the falling edge of the internal SYNC_X
signal. The ROT pin goes high at the rising edge of CLK_Y
and remains high until one sensor clock (CLKIN/4) before
the end of the actual ROT.

Asynchronous Reset
The sensor has a reset pin, RESET_N, and a reset SPI
register, RESET_N_SEQ. Both are active low.
RESET_N is the chip reset. All components on the chip
are reset when this pin is low. This includes the sequencer,
the SPI register, and X and Y shift registers. The reset is
asynchronous.
RESET_N_SEQ is the sequencer reset. Bringing this bit
low only resets the sequencer. This is used to restart the
sequencer with the current SPI settings.
Reset on Startup
When the sensor starts up, RESET_N is kept low until all
RESET_N, RESET_N_SEQ is kept low for an additional
0.5 m s.
During the chip reset the data on the LVDS outputs (data
channels and sync channel) is invalid. When the chip comes
out of reset, but the sequencer is kept in reset, the LVDS
outputs toggle between the idle words.
If RESET_N_SEQ is only low for a short period of time
(100 ns), the pixel array is not completely reset. Information
from the previous integration cycle is still present on the
photodiode. Ensure that the pixels are in reset for at least 3 m s
by keeping RESET_N_SEQ low for a long time, or by not
starting exposure before 3 m s after RESET_N_SEQ.
