The IBIS5-B-1300 image sensor has two shutter types:
0 = synchronous shutter
1 = rolling shutter
Bits FRAME_CAL_MODE and LINE_CAL_MODE define the
calibration mode of the output amplifier.
During every row-blanking period, a calibration is done of the
output amplifier. There are two calibration modes. The FAST
mode (0) forces a calibration in one cycle but is not so accu-
rate and suffers from KTC noise. The SLOW mode (1) only
makes incremental adjustments and is noise free.
Approximately 200 or more ’slow’ calibrations have the same
effect as one ’fast’ calibration. Different calibration modes are
set at the beginning of the frame (FRAME_CAL_MODE bit)
and for every subsequent line that is read (LINE_CAL_MODE
bit). The Y_START input defines the beginning of a frame,
Y_CLOCK defines the beginning of a new row.
Some applications may require the use continuous charging
of the pixel columns instead of a pre-charge on every line
sample operation.
Setting bit CONT_CHARGE to ’1’ activates this function. The
resistor connected to pin PC_CMD controls the current level
on every pixel column.
The system clock is divided several times on-chip. Half the
system clock rate clocks the X-shift-register that controls the
column/pixel readout. Odd and even pixel columns are
switched to two separate buses. In the output amplifier, the
pixel signals on the two buses are combined into one pixel
stream at the same frequency as SYS_CLOCK.

Table 16. SS Sequencer Clock Granularities
The clock that drives the X-sequencer is a multiple of 4, 8, 16, or
32 times the system clock. Clocking the X-sequencer at a slower
rate (longer row blanking time; pixel read out speed is always
equal to the SYSTEM_CLOCK) results in more signal swing for
the same light conditions.

Use
GRAN_SS_SEQ_LSB (bit 6) to program the clock that drives
the ’snapshot’ or synchronous shutter sequencer. This way
the integration time in synchronous shutter mode is a multiple
of 32, 64, 128, or 256 times the system clock period. To over-
come global reset issues, use the longest SS granularity (bits
6 and 7 set to '1').
and 10)
In normal (single slope) mode the pixel reset is controlled from
the left side of the image core using the voltage applied on pin
VDDR_LEFT as pixel reset voltage. In multiple slope opera-
tion, apply one or more variable pixel reset voltages.
