Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. The ADC is 11−bit, down−scaled to 10−bit. The PYTHON uses a larger word−length internally to provide 10−bit on the output.
2. Operating ratings are conditions in which operation of the device is intended to be functional.
3. ON Semiconductor recommends that customers become familiar with, and follow the procedures in JEDEC Standard JESD625−A. Refer
to Application Note AN52561. Long term exposure toward the maximum storage temperature will accelerate color filter degradation.
4. Caution needs to be taken to avoid dried stains on the underside of the glass due to condensation. The glass lid glue is permeable and can
absorb moisture if the sensor is placed in a high % RH environment.

Ray Angle and Microlens Array Information
regards to its photodiode. A shift in microlens position
versus photodiode position will cause a tilted angle of peak
photoresponse, here denoted Chief Ray Angle (CRA).
Microlenses and photodiodes are aligned with 0 shift and
CRA in the center of the array, while the shift and CRA
increases radially towards its edges, as illustrated by
Figure 7.
The purpose of the shifted microlenses is to improve the
uniformity of photoresponse when camera lenses with a
finite exit pupil distance are used. The CRA varies nearly
linearly with distance from the center as illustrated in Figure
8, with a corner CRA of approximately 2.7 degrees. This
edge CRA is matching a lens with exit pupil distance of
∼ 80 mm.
An array of microlenses is placed over the CMOS pixel
array in order to improve the absolute responsivity of the
photodiodes. The combined microlens array and pixel array
has two important properties:
1. Angular dependency of photoresponse of a pixel
The photoresponse of a pixel with microlens in the center
of the array to a fixed optical power with varied incidence
angle is as plotted in Figure 5, where definitions of angles fx
and fy are as described by Figure 6.
2. Microlens shift across array and CRA
The microlens array is fabricated with a slightly smaller
pitch than the array of photodiodes. This difference in pitch
creates a varying degree of shift of a pixel’s microlens with

Image Core
Phase Locked Loop
The image core consists of:
• Pixel Array
• Address Decoders and Row Drivers
• Pixel Biasing
The PYTHON 1300 pixel array contains 1280 (H) x
1024 (V) readable pixels with a pixel pitch of 4.8 mm. The
PYTHON 300 and PYTHON 500 image arrays contain
672 (H) x 512 (V) and 832 (H) x 632 (V) readable pixels
respectively, inclusive of 16 pixel rows and 16 pixel
columns at every side to allow for reprocessing or color
reconstruction. The sensors use in−pixel CDS architecture,
which makes it possible to achieve a low noise read out of
the pixel array in global shutter mode with CDS.
The function of the row drivers is to access the image array
line by line, or all lines together, to reset or read the pixel
data. The row drivers are controlled by the on−chip
sequencer and can access the pixel array.
The pixel biasing block guarantees that the data on a pixel
is transferred properly to the column multiplexer when the
row drivers select a pixel line for readout.
The PLL accepts a (low speed) clock and generates the
required high speed clock. Optionally this PLL can be
bypassed. Typical input clock frequency is 72 MHz.
LVDS Clock Receiver
The LVDS clock receiver receives an LVDS clock signal
and distributes the required clocks to the sensor.
Typical input clock frequency is 360 MHz in 10−bit mode
and 288 MHz in 8−bit mode. The clock input needs to be
terminated with a 100 W resistor.
Column Multiplexer
All pixels of one image row are stored in the column
sample−and−hold (S/H) stages. These stages store both the
reset and integrated signal levels.
The data stored in the column S/H stages is read out
through 8 parallel differential outputs operating at a
frequency of 36 MHz. At this stage, the reset signal and
integrated signal values are transferred into an
FPN−corrected differential signal. A programmable gain of
1x, 2x, or 4x can be applied to the signal. The column

NOIP1SN1300A
In addition to the LVDS data outputs, two extra LVDS
outputs are available. One of these outputs carries the output
clock, which is skew aligned to the output data channels. The
second LVDS output contains frame format synchronization
codes to serve system−level image reconstruction.
multiplexer
also
supports
read−1−skip−1
and
read−2−skip−2 mode. Enabling this mode increases the
frame rate, with a decrease in resolution.
Bias Generator
The bias generator generates all required reference
voltages and bias currents used on chip. An external resistor
of 47 kW, connected between pin IBIAS_MASTER and
gnd_33, is required for the bias generator to operate
properly.
Output MUX (P2−SN/SE)
The output MUX multiplexes the four data channels to
one channel and transmits the data words using a 10−bit
parallel CMOS interface.
Frame synchronization information is communicated by
means of frame and line valid strobes.
Analog Front End
The AFE contains 8 channels, each containing a PGA and
a 10−bit ADC.
For each of the 8 channels, a pipelined 10−bit ADC is used
to convert the analog image data into a digital signal, which
is delivered to the data formatting block. A black calibration
loop is implemented to ensure that the black level is mapped
to match the correct ADC input level.
Channel Multiplexer
The P1−SN/SE/FN LVDS channel multiplexer provides
a 4:2 and 4:1 feature, in addition to utilizing all 4 output
channels.
The P3− SN/SE/FN LVDS channel multiplexer provides
a 2:1 feature, in addition to utilizing both the output
channels.
Data Formatting
The data block receives data from two ADCs and
multiplexes this data to one data stream. A cyclic
redundancy check (CRC) code is calculated on the passing
data.
A frame synchronization data block transmits
synchronization codes such as frame start, line start, frame
end, and line end indications.
The data block calculates a CRC once per line for every
channel. This CRC code can be used for error detection at the
receiving end.

Automatic Exposure Control
The AEC block implements a control system to modulate
the exposure of an image. Both integration time and gains
are controlled by this block to target a predefined
illumination level.

OPERATING MODES
Global Shutter Mode
at the same period of time. The whole pixel core is reset
simultaneously and after the integration time all pixel values
are sampled together on the storage node inside each pixel.
The pixel core is read out line by line after integration. Note
that the integration and readout can occur in parallel or
sequentially. The integration starts at a certain period,
relative to the frame start.
The PYTHON 300, PYTHON 500, and PYTHON 1300
operate in pipelined or triggered global shuttering modes. In
this mode, light integration, light integration takes place on
all pixels in parallel, although subsequent readout is
sequential. Figure 11 shows the integration and readout
sequence for the global shutter. All pixels are light sensitive
Figure 11. Global Shutter Operation
Pipelined Global Shutter Mode
Master Mode
The PYTHON 300, PYTHON 500, and PYTHON 1300
operate in pipelined or triggered global shuttering modes. In
this mode, light, the integration time is set through the
register interface and the sensor integrates and reads out the
images autonomously. The sensor acquires images without
any user interaction.
In pipelined global shutter mode, the integration and
readout are done in parallel. Images are continuously read
and integration of frame N is ongoing during readout of the
previous frame N−1. The readout of every frame starts with
a Frame Overhead Time (FOT), during which the analog
value on the pixel diode is transferred to the pixel memory
element. After the FOT, the sensor is read out line per line
and the readout of each line is preceded by the Row
Overhead Time (ROT). Figure 12 shows the exposure and
readout time line in pipelined global shutter mode.

The slave mode adds more manual control to the sensor.
The integration time registers are ignored in this mode and
the integration time is instead controlled by an external pin.
As soon as the control pin is asserted, the pixel array goes out
of reset and integration starts. The integration continues
until the user or system deasserts the external pin. Upon a
falling edge of the trigger input, the image is sampled and the
readout begins. Figure 13 shows the relation between the
external trigger signal and the exposure/readout timing.

Figure 13. Pipelined Shutter Operated in Slave Mode
Triggered Global Shutter Mode
The triggered global mode can also be controlled in a
master or in a slave mode.
Master Mode
In this mode, a rising edge on the synchronization pin is
used to trigger the start of integration and readout. The
integration time is defined by a register setting. The sensor
autonomously integrates during this predefined time, after
which the FOT starts and the image array is readout
sequentially. A falling edge on the synchronization pin does
not have any impact on the readout or integration and
subsequent frames are started again for each rising edge.
Figure 14 shows the relation between the external trigger
signal and the exposure/readout timing.
If a rising edge is applied on the external trigger before the
exposure time and FOT of the previous frame is complete,
it is ignored by the sensor.
In this mode, manual intervention is required to control
both the integration time and the start of readout. After the
integration time, indicated by a user controlled pin, the
image core is read out. After this sequence, the sensor goes
to an idle mode until a new user action is detected.
The three main differences with the pipelined global
shutter mode are:
• Upon user action, one single image is read.
• Normally, integration and readout are done
sequentially. However, the user can control the sensor
in such a way that two consecutive batches are
overlapping, that is, having concurrent integration and
readout.
• Integration and readout is under user control through an
external pin.
This mode requires manual intervention for every frame.
The pixel array is kept in reset state until requested.

Integration time control is identical to the pipelined
shutter slave mode. An external synchronization pin
controls the start of integration. When it is de−asserted, the
FOT starts. The analog value on the pixel diode is
transferred to the pixel memory element and the image
readout can start. A request for a new frame is started when
the synchronization pin is asserted again.

Normal and Zero Row Overhead Time (ROT) Modes
can thus be longer, however the perceived ROT will be
shorter (‘overhead’ spent per line is reduced). The
integration time and gain parameters can be reconfigured
without any visible image artifact in Normal ROT mode.
Column−level offset corrections are required in Zero ROT
mode. Refer to Column−Level Image Correction
application note in the PYTHON Developer’s Guide
AND9362/D available at the Image Sensor Portal.
This operation mode can be used for two reasons:
• Reduced total line time.
• Lower power due of reduced clock−rate.
In pipelined global shutter mode, the integration and
readout are done in parallel. Images are continuously read
out and integration of frame N is ongoing during readout of
the previous frame N−1. The readout of every frame starts
with a Frame Overhead Time (FOT), during which the
analog value of the pixel diode is transferred to the pixel
memory element. After the FOT, the sensor is read out line
by line and the readout of each line is preceded by a Row
Overhead Time (ROT) as shown in Figure 15.
In Reduced/Zero ROT operation mode (refer to
Figure 16), the row blanking and kernel readout occur in
parallel. This mode is called reduced ROT as a part of the
ROT is done while the image row is readout. The actual ROT

Sensor States
Running
Low Power Standby
In running state, the sensor is enabled and grabbing
images. The sensor can be operated in global master/slave
modes.
In low power standby state, all power supplies are on, but
internally every block is disabled. No internal clock is
running (PLL / LVDS clock receiver is disabled).
All register settings are unchanged.
Only a subset of the SPI registers is active for read/write
in order to be able to configure clock settings and leave the
low power standby state. The only SPI registers that should
be touched are the ones required for the ‘Enable Clock
Management’ action described in Enable Clock
Management − Part 1 on page 18
User Actions: Power Up Functional Mode Sequences
Power Up Sequence
Figure 18 shows the power up sequence of the sensor. The
figure indicates that the first supply to ramp−up is the
vdd_18 supply, followed by vdd_33 and vdd_pix
respectively. It is important to comply with the described
sequence. Any other supply ramping sequence may lead to
high current peaks and, as consequence, a failure of the
sensor power up.
The clock input should start running when all supplies are
stabilized. When the clock frequency is stable, the reset_n
signal can be de−asserted. After a wait period of 10 ms, the
power up sequence is finished and the first SPI upload can
be initiated.
NOTE: The ‘clock input’ can be the CMOS PLL clock
input (clk_pll), or the LVDS clock input
(lvds_clock_inn/p) in case the PLL is bypassed.
Standby (1)
In standby state, the PLL/LVDS clock receiver is running,
but the derived logic clock signal is not enabled.
Standby (2)
In standby state, the derived logic clock signal is running.
All SPI registers are active, meaning that all SPI registers
can be accessed for read or write operations. All other blocks
are disabled.
Idle
In the idle state, all internal blocks are enabled, except the
sequencer block. The sensor is ready to start grabbing
images as soon as the sequencer block is enabled.

serial, P2−SN/SE 10−bit parallel, ...) are available to
customers under NDA at the ON Semiconductor Image
Sensor Portal.
In the serial modes, if the PLL is not used, the LVDS clock
input must be running.
In the P2−SN/SE 10−bit parallel mode, the PLL is
bypassed. The clk_pll clock is used as sensor clock.
It is important to follow the upload sequence listed in
Table 6.
The ‘Enable Clock Management’ action configures the
clock management blocks and activates the clock generation
and distribution circuits in a pre−defined way. First, a set of
clock settings must be uploaded through the SPI register.
These settings are dependent on the desired operation mode
of the sensor.
Table 6 shows the SPI uploads to be executed to configure
the sensor for P1−SN/SE/FN, P3−SN/SE/FN 10−bit serial
mode, with the PLL, and all available LVDS channels.
Note that the SPI uploads to be executed to configure the

Use of Phase Locked Loop
Check the PLL_lock flag 24[0] by reading the SPI
register. When the flag is set, the ‘Enable Clock
Management− Part 2’ action can be continued. When PLL
is not used, this step can be bypassed as shown in Figure 17
on page 16.
If PLL is used, the PLL is started after the upload of the
SPI registers. The PLL requires (dependent on the settings)
some time to generate a stable output clock. A lock detect
circuit detects if the clock is stable. When complete, this is
flagged in a status register.
NOTE: The lock detect status must not be checked for
the P2−SN/SE sensor.

Power Down Sequence
Figure 19 illustrates the timing diagram of the preferred
power down sequence. It is important that the sensor is in
reset before the clock input stops running. Otherwise, the
internal PLL becomes unstable and the sensor gets into an
unknown state. This can cause high peak currents.
The same applies for the ramp down of the power
supplies. The preferred order to ramp down the supplies is
first vdd_pix, second vdd_33, and finally vdd_18. Any other
sequence can cause high peak currents.
NOTE: The ‘clock input’ can be the CMOS PLL clock
input (clk_pll), or the LVDS clock input
(lvds_clock_inn/p) in case the PLL is bypassed.

Sensor Reconfiguration
Sensor Configuration
During the standby, idle, or running state several sensor
parameters can be reconfigured.
• Frame Rate and Exposure Time: Frame rate and
exposure time changes can occur during standby, idle,
and running states by modifying registers 199 to 203.
Refer to page 30−32 for more information.
• Signal Path Gain: Signal path gain changes can occur
during standby, idle, and running states by modifying
registers 204/205. Refer to page 37 for more
information.
• Windowing: Changes with respect to windowing can
occur during standby, idle, and running states. Refer to
Multiple Window Readout on page 32 for more
information.
• Subsampling: Changes of the subsampling mode can
occur during standby, idle, and running states by
modifying register 192. Refer to Subsampling on
page 33 for more information.
• Shutter Mode: The shutter mode can only be changed
during standby or idle mode by modifying register 192.
Reconfiguring the shutter mode during running state is
not supported.
This device contains multiple configuration registers.
Some of these registers can only be configured while the
sensor is not acquiring images (while register 192[0] = 0),
while others can be configured while the sensor is acquiring
images. For the latter category of registers, it is possible to
distinguish the register set that can cause corrupted images
(limited number of images containing visible artifacts) from
the set of registers that are not causing corrupted images.
These three categories are described here.
Static Readout Parameters
Some registers are only modified when the sensor is not
acquiring images. Reconfiguration of these registers while
images are acquired can cause corrupted frames or even
interrupt the image acquisition. Therefore, it is
recommended to modify these static configurations while
the sequencer is disabled (register 192[0] = 0). The registers
shown in Table 15 should not be reconfigured during image
acquisition. A specific configuration sequence applies for
these registers. Refer to the operation flow and startup
description.

Dynamic Configuration Potentially Causing Image
Artifacts
image containing visible artifacts. A typical example of a
corrupted image is an image which is not uniformly
exposed.
The effect is transient in nature and the new configuration
is applied after the transient effect.
The category of registers as shown in Table 16 consists of
configurations that do not interrupt the image acquisition
process, but may lead to one or more corrupted images
during and after the reconfiguration. A corrupted image is an

Reconfiguration of these registers may have an impact on the black−level

Dynamic Readout Parameters
shown in Table 17. Some reconfiguration may lead to one
frame being blanked. This happens when the modification
requires more than one frame to settle. The image is blanked
out and training patterns are transmitted on the data and sync
channels.
It is possible to reconfigure the sensor while it is acquiring
images. Frame related parameters are internally
resynchronized to frame boundaries, such that the modified
parameter does not affect a frame that has already started.
However, there can be restrictions to some registers as

Subsampling/binning
192[7]
192[8]
Description
Subsampling or binning is synchronized to a new frame start.
ROI configuration
195
256–303
A ROI switch is only detected when a new window is selected as the active window
(reconfiguration of register 195). reconfiguration of the ROI dimension of the active window does not
lead to a frame blank and can cause a corrupted image.
Exposure
reconfiguration
199−203
Exposure reconfiguration does not cause artifact. However, a latency of one frame is observed unless
reg_seq_exposure_sync_mode is set to ‘1’ in triggered global mode (master).
204
Gains are synchronized at the start of a new frame. Optionally, one frame latency can be incorporated
to align the gain updates to the exposure updates
(refer to register 204[13] − gain_lat_comp).
Gain reconfiguration
Freezing Active Configurations
them for the coming frames. The freezing of the active set
of registers can be programmed in the sync_configuration
registers, which can be found at the SPI address 206.
Figure 20 shows a reconfiguration that does not use the
sync_configuration option. As depicted, new SPI
configurations are synchronized to frame boundaries.
Figure 21 shows the usage of the sync_configuration
settings. Before uploading a set of registers, the
corresponding sync_configuration is de−asserted. After the
upload is completed, the sync_configuration is asserted
again and the sensor resynchronizes its set of registers to the
coming frame boundaries. As seen in the figure, this ensures
that the uploads performed at the end of frame N+2 and the
start of frame N+3 become active in the same frame (frame
N+4).
Though the readout parameters are synchronized to frame
boundaries, an update of multiple registers can still lead to
a transient effect in the subsequent images, as some
configurations require multiple register uploads. For
example, to reconfigure the exposure time in master global
mode, both the fr_length and exposure registers need to be
updated. Internally, the sensor synchronizes these
configurations to frame boundaries, but it is still possible
that the reconfiguration of multiple registers spans over two
or even more frames. To avoid inconsistent combinations,
freeze the active settings while altering the SPI registers by
disabling synchronization for the corresponding
functionality before reconfiguration. When all registers are
uploaded, re−enable the synchronization. The sensor’s
sequencer then updates its active set of registers and uses

The sensor continues with its previous configurations.
Note: The window configurations themselves are not frozen. reconfiguration of
active windows is not gated by this setting.
Window Configuration
Black Calibration
The sensor automatically calibrates the black level for
each frame. Therefore, the device generates a configurable
number of electrical black lines at the start of each frame.
The desired black level in the resulting output interface can
be configured and is not necessarily targeted to ‘0’.
Configuring the target to a higher level yields some
information on the left side of the black level distribution,
while the other end of the distribution tail is clipped to ‘0’
when setting the black level target to ‘0’.
The black level is calibrated for the 8 columns contained
in one kernel. This implies 8 black level offsets are generated
and applied to the corresponding columns. Configurable
parameters for the black−level algorithm are listed in
Table 19.
Global Shutter Mode
Up to 8 windows can be defined in global shutter mode
(pipelined or triggered). The windows are defined by
registers 256 to 303. Each window can be activated or
deactivated separately using register 195. It is possible to
reconfigure the inactive windows while the sensor is
acquiring images.
Switching between predefined windows is achieved by
activation of the respective windows. This way a minimum
number of registers need to be uploaded when it is necessary
to switch between two or more sets of windows. As an
example of this, scanning the scene at higher frame rates
using multiple windows and switching to full frame capture
when the object is tracked. Switching between the two
modes only requires an upload of one register.

197[7:0]
black_lines
This register configures the number of black lines that are generated at the start of a frame. At least one
black line must be generated. The maximum number is 255.
Note: When the automatic black−level calibration algorithm is enabled, make sure that this register is
configured properly to produce sufficient black pixels for the black−level filtering.
The number of black pixels generated per line is dependent on the operation mode and window configurations:
Each black line contains 162 kernels.
197[12:8]
gate_first_line
A number of black lines are blanked out when a value different from 0 is configured. These blanked out
lines are not used for black calibration. It is recommended to enable this functionality, because the first
line can have a different behavior caused by boundary effects. When enabling, the number of black
lines must be set to at least two in order to have valid black samples for the calibration algorithm.
129[0]
auto_blackcal_enable
Internal black−level calibration functionality is enabled when set to ‘1’. Required black level offset compensation is calculated on the black samples and applied to all image pixels.
When set to ‘0’, the automatic black−level calibration functionality is disabled. It is possible to apply an
offset compensation to the image pixels, which is defined by the registers 129[10:1].
Note: Black sample pixels are not compensated; the raw data is sent out to provide
external statistics and, optionally, calibrations.
129[9:1]
blackcal_offset
Black calibration offset that is added or subtracted to each regular pixel value when auto_blackcal_enable is set to ‘0’. The sign of the offset is determined by register 129[10] (blackcal_offset_dec).
Note: All channels use the same offset compensation when automatic black calibration is disabled.
129[10]
blackcal_offset_dec
Sign of blackcal_offset. If set to ‘0’, the black calibration offset is added to each pixel. If set to ‘1’, the
black calibration offset is subtracted from each pixel.
This register is not used when auto_blackcal_enable is set to ‘1’.

black_samples
The black samples are low−pass filtered before being used for black level calculation. The more samples are taken into account, the more accurate the calibration, but more samples require more black
lines, which in turn affects the frame rate.
The effective number of samples taken into account for filtering is 2^ black_samples.
Note: An error is reported by the device if more samples than available are requested (refer to register
136).
Black Level Filtering Monitoring

blackcal_error0
An error is reported by the device if there are requests for more samples than are available (each bit
corresponding to one data path). The black level is not compensated correctly if one of the channels
indicates an error. There are three possible methods to overcome this situation and to perform a correct
offset compensation:
• Increase the number of black lines such that enough samples are generated at the cost of increasing frame time (refer to register 197).
• Relax the black calibration filtering at the cost of less accurate black level determination (refer to
register 128).
• Disable automatic black level calibration and provide the offset via SPI register upload. Note that
the black level can drift in function of the temperature. It is thus recommended to perform the offset
calibration periodically to avoid this drift.
NOTE: The maximum number of samples taken into account for black level statistics is half the number of kernels.

Serial Peripheral Interface
The sck clock is passed through to the sensor as
indicated in Figure 22. The sensor samples this
data on a rising edge of the sck clock (mosi needs
to be driven by the system on the falling edge of
the sck clock).
5. The tenth bit sent by the master indicates the type
of transfer: high for a write command, low for a
read command.
6. Data transmission:
- For write commands, the master continues
sending the 16−bit data, most significant bit first.
- For read commands, the sensor returns the
requested address on the miso pin, most significant
bit first. The miso pin must be sampled by the
system on the falling edge of sck (assuming
nominal system clock frequency and maximum
10 MHz SPI frequency).
7. When data transmission is complete, the system
deselects the sensor one clock period after the last
bit transmission by pulling ss_n high.
Note that the maximum frequency for the SPI interface
scales with the input clock frequency, bit depth and LVDS
output multiplexing as described in Table 5.
Consecutive SPI commands can be issued by leaving at
least two SPI clock periods between two register uploads.
Deselect the chip between the SPI uploads by pulling the
ss_n pin high.
The sensor configuration registers are accessed through
an SPI. The SPI consists of four wires:
• sck: Serial Clock
• ss_n: Active Low Slave Select
• mosi: Master Out, Slave In, or Serial Data In
• miso: Master In, Slave Out, or Serial Data Out
The SPI is synchronous to the clock provided by the
master (sck) and asynchronous to the sensor’s system clock.
When the master wants to write or read a sensor’s register,
it selects the chip by pulling down the Slave Select line
(ss_n). When selected, data is sent serially and synchronous
to the SPI clock (sck).
Figure 22 shows the communication protocol for read and
write accesses of the SPI registers. The PYTHON 300,
PYTHON 500, and PYTHON 1300 image sensors use 9−bit
addresses and 16−bit data words.
Data driven by the system is colored blue in Figure 16,
while data driven by the sensor is colored yellow. The data
in grey indicates high−Z periods on the miso interface. Red
markers indicate sampling points for the sensor (mosi
sampling); green markers indicate sampling points for the
system (miso sampling during read operations).
The access sequence is:
3. Select the sensor for read or write by pulling down
the ss_n line.
4. One SPI clock cycle after selecting the sensor, the
9−bit data is transferred, most significant bit first.

IMAGE SENSOR TIMING AND READOUT
reset period, the global photodiode reset condition is
abandoned. This indicates the start of the integration or
exposure time. The length of the exposure time is defined by
the registers exposure and mult_timer.
NOTE: The start of the exposure time is synchronized to
the start of a new line (during ROT) if the
exposure period starts during a frame readout.
As a consequence, the effective time during
which the image core is in a reset state is
extended to the start of a new line.
• Make sure that the sum of the reset time and exposure
time exceeds the time required to readout all lines. If
this is not the case, the exposure time is extended until
all (active) lines are read out.
• Alternatively, it is possible to specify the frame time
and exposure time. The sensor automatically calculates
the required reset time. This mode is enabled by the
fr_mode register. The frame time is specified in the
register fr_length.
The following sections describe the configurations for
single slope reset mechanism. Dual and triple slope handling
during global shutter operation is similar to the single slope
operation. Extra integration time registers are available.
Global Shutter Mode
Pipelined Global Shutter (Master)
The integration time is controlled by the registers
fr_length[15:0] and exposure[15:0]. The mult_timer
configuration defines the granularity of the registers
reset_length and exposure. It is read as number of system
clock cycles (14.706 ns nominal at 68 MHz) for the
P1−SN/SE/FN, P3−SN/SE/FN version and 18 MHz cycles
(55.556 ns nominal) for the P2−SN/SE version.
The exposure control for (Pipelined) Global Master mode
is depicted in Figure 23.
The pixel values are transferred to the storage node during
FOT, after which all photo diodes are reset. The reset state
remains active for a certain time, defined by the reset_length
and mult_timer registers, as shown in the figure. Note that
meanwhile the image array is read out line by line. After this

other words, the high time of the trigger pin indicates the

frame time.
The use of the trigger during slave mode is shown in
Figure 25.
Notes:
• The falling edge on the trigger pin does not have any
impact. Note however the trigger must be asserted for
at least 100 ns.
• The start of the exposure time is synchronized to the
start of a new line (during ROT) if the exposure period
starts during a frame readout. As a consequence, the
effective time during which the image core is in a reset
state is extended to the start of a new line.
• If the exposure timer expires before the end of readout,
the exposure time is extended until the end of the last
active line.
• The trigger pin needs to be kept low during the FOT.
The monitor pins can be used as a feedback to the
FPGA/controller (eg. use monitor0, indicating the very
first line when monitor_select = 0x5 − a new trigger can
be initiated after a rising edge on monitor0).

ADDITIONAL FEATURES
Multiple Window Readout
y1_end
The PYTHON 300, PYTHON 500, and PYTHON 1300
image sensors support multiple window readout, which
means that only the user−selected Regions Of Interest (ROI)
are read out. This allows limiting data output for every
frame, which in turn allows increasing the frame rate. In
global shutter mode, up to eight ROIs can be configured.

Restrictions
The following restrictions for each line are assumed for
the user configuration:
• Windows are ordered from left to right, based on their
x−start address:
x-start x-end
Figure 26. Region of Interest Configuration
x_start_roi(i) v x_start_roi(j) AND
• x−start[7:0]
x_end_roi(i) vx_end_roi(j)
x−start defines the x−starting point of the desired window.
The sensor reads out 8 pixels in one single clock cycle. As
a consequence, the granularity for configuring the x−start
position is also 8 pixels for no sub sampling. The value
configured in the x−start register is multiplied by 8 to find
the corresponding column in the pixel array.
• x−end[7:0]
This register defines the window end point on the x−axis.
Similar to x−start, the granularity for this configuration is
one kernel. x−end needs to be larger than x−start.
• y−start[9:0]
The starting line of the readout window. The granularity
of this setting is one line, except with color sensors where it
needs to be an even number.
• y−end[9:0]
The end line of the readout window. y−end must be
configured larger than y−start. This setting has the same
granularity as the y−start configuration.
Up to eight windows can be defined, possibly (partially)
overlapping, as illustrated in Figure 27.
Where j > i
Processing Multiple Windows
The sequencer control block houses two sets of counters
to construct the image frame. As previously described, the
y−counter indicates the line that needs to be read out and is
incremented at the end of each line. For the start of the frame,
it is initialized to the y−start address of the first window and
it runs until the y−end address of the last window to be read
out. The last window is configured by the configuration
registers and it is not necessarily window #7.
The x−counter starts counting from the x−start address of
the window with the lowest ID which is active on the
addressed line. Only windows for which the current
y−address is enclosed are taken into account for scanning.
Other windows are skipped.
www.onsemi.com

NOIP1SN1300A
• The read pointer is not necessarily incremented by one,
Figure 28 illustrates a practical example of a
configuration with five windows. The current position of the
read pointer (ys) is indicated by a red line crossing the image
array. For this position of the read pointer, three windows
need to be read out. The initial start position for the x−kernel
pointer is the x−start configuration of ROI1. Kernels are
scanned up to the ROI3 x−end position. From there, the
x−pointer jumps to the next window, which is ROI4 in this
illustration. When reaching ROI4’s x−end position, the read
pointer is incremented to the next line and xs is reinitialized
to the starting position of ROI1.
Notes:
• The starting point for the readout pointer at the start of
a frame is the y−start position of the first active
window.
•
•
•
but depending on the configuration, it can jump in
y−direction. In Figure 28, this is the case when reaching
the end of ROI0 where the read pointer jumps to the
y−start position of ROI1
The x−pointer starting position is equal to the x−start
configuration of the first active window on the current
line addressed. This window is not necessarily window
#0.
The x−pointer is not necessarily incremented by one
each cycle. At the end of a window it can jump to the
start of the next window.
Each window can be activated separately. There is no
restriction on which window and how many of the 8
windows are active.

Subsampling
Color Sensors
Subsampling is used to reduce the image resolution. This
allows increasing the frame rate. Two subsampling modes
are supported: for monochrome and NIR enhanced sensors
(P1−SN/FN, P2−SN and P3−SN/FN) and color sensors
(P1−SE / P2−SE / P3−SE).
For color sensors, the read−2−skip−2 subsampling
scheme is used. Subsampling occurs both in x− and y−
direction. Figure 29 shows which pixels are read and which
ones are skipped.
Monochrome and NIR Sensors
These sensors utilize the read−1−skip−1 subsampling
scheme. Subsampling occurs both in x− and y− direction.

Binning
Multiple Slope Integration
Pixel binning is a technique in which different pixels
belonging to a rectangular bin are averaged in the analog
domain. Two−by−two pixel binning is available with the
monochrome and NIR enhanced image sensors (P1−SN/FN,
P2−SN, P3−SN/FN). This implies that two adjacent pixels
are averaged both in column and row. Binning is
configurable using a register setting. Pixel binning is not
supported on PYTHON color option (P1−SE / P2−SE /
P3−SE) and in Zero ROT mode.
NOTES:
1. Register 194[13:12] needs to be configured to 0x0
for 2x2 pixel binning and to 0x1 for 2x1 binning.
Binning occurs only in x direction.
2. Binning in y-direction cannot be used in
combination with pipelined integration and
readout. The integration time and readout time
should be separated in time (do not coincide).
‘Multiple Slope Integration’ is a method to increase the
dynamic range of the sensor. The PYTHON 300,
PYTHON 500, and PYTHON 1300 support up to three
slopes.
Figure 30 shows the sensor response to light when the
sensor is used with one slope, two slopes, and three slopes.
The X−axis represents the light power; the Y−axis shows the
sensor output signal. The kneepoint of the multiple slope
curves are adjustable in both position and voltage level.
It is clear that when using only one slope (red curve), the
sensor has the same responsivity over the entire range, until
the output saturates at the point indicated with ‘single slope
saturation point’.
To increase the dynamic range of the sensor, a second
slope is applied in the dual slope mode (green curve). The
sensor has the same responsivity in the black as for a single
slope, but from ‘knee point 1’ on, the sensor is less
responsive to incoming light. The result is that the saturation
point is at a higher light power level.
To further increase the dynamic range, a third slope can be
applied, resulting in a second knee point.
The multiple slope function is only available in global
shutter modes. Refer to section Global Shutter Mode on
page 30 for general notes applicable to the global shutter
operation and more particular to the use of the trigger0 pin.
Reverse Readout in Y−direction
Reverse readout in y−direction can be done by toggling
reverse_y (reg 194[8]). The reference for y_start and y_end
pointers is reversed.

Kneepoint Configuration (Multiple Slope Reset Levels)
dual_slope_enable and triple_slope_enable and their values
are defined by the registers exposure_ds and exposure_ts.
NOTE: Dual and triple slope sequences must start after
readout of the previous frame is fully completed.
Figure 31 shows the frame timing for pipelined master
mode with dual and triple slope integration and
fr_mode = ‘0’ (fr_length representing the reset length).
In triggered master mode, the start of integration is
initiated by a rising edge on trigger0, while the falling edge
does not have any relevance. Exposure duration and
dual/triple slope points are defined by the registers.
The kneepoint reset levels are configured by means of
DAC configurations in the image core. The dual slope
kneepoint is configured with the dac_ds configuration,
while the triple slope kneepoint is configured with the
dac_ts register setting. Both are located on address 41.
Multiple Slope Integration in “Master Mode” (Pipelined
or Triggered)
In master mode, the time stamps for the double and triple
slope resets are configured in a similar way as the exposure
time. They are enabled through the registers
Figure 31. Multiple Slope Operation in Master Mode for fr_mode = ‘0’ (Pipelined)
Slave Mode
In slave mode, the register settings for integration control are ignored. The user has full control through the trigger0, trigger1
and trigger2 pins. A falling edge on trigger1 initiates the dual slope reset while a falling edge on trigger2 initiates the triple
slope reset sequence. Rising edges on trigger1 and trigger2 do not have any impact.
NOTE: Dual and triple slope sequences must start after readout of the previous frame is fully completed.

Black Reference
Signal Path Gain
The sensor reads out one or more black lines at the start of
every new frame. The number of black lines to be generated
is programmable and is minimal equal to 1. The length of the
black lines depends on the operation mode. The sensor
always reads out the entire line (160 kernels), independent
of window configurations.
The black references are used to perform black calibration
and offset compensation in the data channels. The raw black
pixel data is transmitted over the usual output interface,
while the regular image data is compensated (can be
bypassed).
On the output interface, black lines can be seen as a
separate window, however without Frame Start and Ends
(only Line Start/End). The Sync code following the Line
Start and Line End indications (“window ID”) contains the
active window number, which is 0. Black reference data is
classified by a BL code.
Analog Gain Stages
Referring to Table 21, three gain settings are available in
the analog data path to apply gain to the analog signal before
it is digitized. The gain amplifier can apply a gain of
approximately 1x to 4x to the analog signal.
The moment a gain reconfiguration is applied and
becomes valid can be controlled by the gain_lat_comp
configuration.
With ‘gain_lat_comp’ set to ‘0’, the new gain
configurations are applied from the very next frame.
With ‘gain_lat_comp’ set to ‘1’, the new gain settings are
postponed by one extra frame. This feature is useful when
exposure time and gain are reconfigured together, as an
exposure time update always has one frame latency.

AEC Statistics Block
Three main blocks can be distinguished:
• The statistics block compares the average of the
current image’s samples to the configured target value
for the average illumination of all pixels
• The relative gain change request from the statistics
block is filtered through the AEC Filter block in the
time domain (low pass filter) before being integrated.
The output of the filter is the total requested gain in the
complete signal path.
• The enforcer block accepts the total requested gain and
distributes this gain over the integration time and gain
stages (both analog and digital)
The statistics block calculates the average illumination of
the current image. Based on the difference between the
calculated illumination and the target illumination the
statistics block requests a relative gain change.
Statistics Subsampling and Windowing
For average calculation, the statistics block will
sub−sample the current image or windows by taking every
fourth sample into account. Note that only the pixels read out
through the active windows are visible for the AEC. In the
case where multiple windows are active, the samples will be
selected from the total samples. Samples contained in a
region covered by multiple (overlapping) window will be
taking into account only once.
It is possible to define an AEC specific sub−window on
which the AEC will calculate it’s average. For instance, the
sensor can be configured to read out a larger frame, while the
illumination is measured on a smaller region of interest, e.g.
center weighted as shown in Table 22.
The automatic exposure control loop is enabled by asserting
the aec_enable configuration in register 160.
NOTE: Dual and Triple slope integration is not
supported in conjunction with the AEC.

by roi_aec
Description
253−255
roi_aec
These registers define a window from which the AEC samples will be selected when roi_aec_enable is
asserted. Configuration is similar to the regular region of interests.
The intersection of this window with the active windows define the selected pixels. It is important that this
window at least overlaps with one or more active windows.

AEC Filter Block
Target Illumination
The target illumination value is configured by means of
register desired_intensity as shown in Table 23.
The filter block low−pass filters the gain change requests
received from the statistics block.
The filter can be restarted by asserting the restart_filter
configuration of register 160.

desired_intensity
Target intensity value, on 10−bit scale.
For 8−bit mode, target value is configured on desired_intensity[9:2]
The enforcer block calculates the four different gain
parameters, based on the required total gain, thereby
respecting a specific hierarchy in those configurations.
Some (digital) hysteresis is added so that the (analog) sensor
settings don’t need to change too often.
Exposure Control Parameters
The several gain parameters are described below, in the
order in which these are controlled by the AEC for large
adjustments. Small adjustments are regulated by digital gain
only.
• Exposure Time
The exposure is the time between the global image array
reset de−assertion and the pixel charge transfer. The
granularity of the integration time steps is configured by the
mult_timer register.
NOTE: The exposure_time register is ignored when the
AEC is enabled. The register fr_length defines
the frame time and needs to be configured
accordingly.
• Analog Gain
The sensor has two analog gain stages, configurable
independently from each other. Typically the AEC shall only
regulate the first stage.
• Digital Gain
The last gain stage is a gain applied on the digitized
samples. The digital gain is represented by a 5.7 unsigned
number (i.e. 7 bits after the decimal point). While the analog
gain steps are coarse, the digital gain stage makes it possible
to achieve very fine adjustments.
Color Sensor
The weight of each color can be configured for color
sensors by means of scale factors. Note these scale factor are
only used to calculate the statistics in order to compensate
for (off−chip) white balancing and/or color matrices. The
pixel values itself are not modified.
The scale factors are configured as 3.7 unsigned numbers
(0x80 = unity). Refer to Table 24 for color scale factors. For
mono sensors, configure these factors to their default value.

The control range for each of the exposure parameters can
be pre−programmed in the sensor. Table 25 lists the relevant
registers.

CONTROL PARAMETERS
As an integration time update has a latency of one frame,
the exposure control parameters are evaluated and updated
every other frame.
Note: The gain update latency must be postpone to match
the integration time latency. This is done by asserting the
gain_lat_comp register on address 204[13].

Temperature Sensor
low respectively. The temperature sensor is reset or disabled
when the input reg_tempd_enable is set to a digital low state.
The PYTHON 300, PYTHON 500, and PYTHON 1300
image sensors have an on−chip temperature sensor which
returns a digital code (Tsensor) of the silicon junction
temperature. The Tsensor output is a 8−bit digital count
between 0 and 255, proportional to the temperature of the
silicon substrate. This reading can be translated directly to
a temperature reading in °C by calibrating the 8−bit readout
at 0°C and 85°C to achieve an output accuracy of ±2°C. The
Tsensor output can also be calibrated using a single
temperature point (example: room temperature or the
ambient temperature of the application), to achieve an
output accuracy of ±5°C.
Note that any process variation will result in an offset in
the bit count and that offset will remain within ±5°C over the
temperature range of 0°C and 85°C. Tsensor output digital
code can be read out through the SPI interface.
Calibration using one temperature point
The temperature sensor resolution is fixed for a given type
of package for the operating range of 0°C to +85°C and
hence devices can be calibrated at any ambient temperature
of the application, with the device configured in the mode of
operation.
Interpreting the actual temperature for the digital code
readout:
The formula used is
TJ = R (Nread − Ncalib) + Tcalib
TJ = junction die temperature
R = resolution in degrees/LSB (typical 0.75 deg/LSB)
Nread = Tsensor output (LSB count between 0 and 255)
Tcalib = Tsensor calibration temperature
Ncalib = Tsensor output reading at Tcalib
Output of the temperature sensor to the SPI:
tempd_reg_temp<7:0>: This is the 8−bit N count readout
proportional to temperature.
Monitor Pins
The internal sequencer has two monitor outputs (Pin 44
and Pin 45) that can be used to communicate the internal
states from the sequencer. A three−bit register configures the
assignment of the pins as shown in Table 28.
Input from the SPI:
The reg_tempd_enable is a global enable and this enables
or disables the temperature sensor when logic high or logic

DATA OUTPUT FORMAT
Frame Format
The PYTHON 300, PYTHON 500, and PYTHON 1300
image sensors are available in two LVDS output
configuration, P1 and P3.
The P1 configuration utilizes four LVDS output channels
together with an LVDS clock output and an LVDS
synchronization output channel.
The P3 configuration consists of two LVDS output
channels together with an LVDS clock output and an LVDS
synchronization output channel.
The PYTHON 1300 is also available in a CMOS output
configuration − P2, which includes a 10−bit parallel CMOS
output together with a CMOS clock output and ‘frame valid’
and ‘line valid’ CMOS output signals.
The frame format in 8−bit mode is identical to the 10−bit
mode with the exception that the Sync and data word depth
is reduced to eight bits.
The frame format in 10−bit mode is explained by example
of the readout of two (overlapping) windows as shown in
Figure 34(a).
The readout of a frame occurs on a line−by−line basis. The
read pointer goes from left to right, bottom to top.
Figure 34 indicates that, after the FOT is completed, the
sensor reads out a number of black lines for black calibration
purposes. After these black lines, the windows are
processed. First a number of lines which only includes
information of ‘ROI 0’ are sent out, starting at position
y0_start. When the line at position y1_start is reached, a
number of lines containing data of ‘ROI 0’ and ‘ROI 1’ are
sent out, until the line position of y0_end is reached. From
there on, only data of ‘ROI 1’ appears on the data output
channels until line position y1_end is reached
During read out of the image data over the data channels,
the sync channel sends out frame synchronization codes
which give information related to the image data that is sent
over the four data output channels.
Each line of a window starts with a Line Start (LS)
indication and ends with a Line End (LE) indication. The
line start of the first line is replaced by a Frame Start (FS);
the line end of the last line is replaced with a Frame End
indication (FE). Each such frame synchronization code is
followed by a window ID (range 0 to 7). For overlapping
windows, the line synchronization codes of the overlapping
windows with lower IDs are not sent out (as shown in the
illustration: no LE/FE is transmitted for the overlapping part
of window 0).
NOTE: In Figure 34, only Frame Start and Frame End
Sync words are indicated in (b). CRC codes are
also omitted from the figure.
P1−SN/SE/FN, P3−SN/SE/FN: LVDS Interface Version
LVDS Output Channels
The image data output occurs through four LVDS data
channels where a synchronization LVDS channel and an
LVDS output clock signal synchronizes the data. Referring
to Table 21, the four data channels on the P1 option are used
to output the image data only, while on the P3 option, two
data channel channels are utilized. The sync channel
transmits information about the data sent over these data
channels (includes codes indicating black pixels, normal
pixels, and CRC codes).
8−bit / 10−bit Mode
The sensor can be used in 8−bit or 10−bit mode.
In 10−bit mode, the words on data and sync channel have
a 10−bit length. The output data rate is 720 Mbps.
In 8−bit mode, the words on data and sync channel have
an 8−bit length, the output data rate is 576 Mbps.
Note that the 8−bit mode can only be used to limit the data
rate at the consequence of image data word depth. It is not
supported to operate the sensor in 8−bit mode at a higher
clock frequency to achieve higher frame rates.
The P1 option supports 10−bit/8−bit in ZROT/NROT
mode, while the P3 option supports 10−bit NROT mode
only.

synchronization codes, please refer to
Application Note AND5001.

Cyclic Redundancy Code
LVDS Output Multiplexing
At the end of each line, a CRC code is calculated to allow
error detection at the receiving end. Each data channel
transmits a CRC code to protect the data words sent during
the previous cycles. Idle and training patterns are not
included in the calculation.
The sync channel is not protected. A special character
(CRC indication) is transmitted whenever the data channels
send their respective CRC code.
The polynomial in 10−bit operation mode is
x10 + x9 + x6 + x3 + x2 + x + 1. The CRC encoder is seeded
at the start of a new line and updated for every (valid) data
word received. The CRC seed is configurable using the
crc_seed register. When ‘0’, the CRC is seeded by all−‘0’;
when ‘1’ it is seeded with all−‘1’.
In 8−bit mode, the polynomial is x8 + x6 + x3 + x2 + 1.
The CRC seed is configured by means of the crc_seed
register.
NOTE: The CRC is calculated for every line. This
implies that the CRC code can protect lines from
multiple windows.
The PYTHON300, PYTHON500 and PYTHON1300
image sensors contain a function for down−multiplexing the
output channels. Using this function, one may for instance
use the device with 2 or 1 data channels instead of 4 data
channels.
Enabling the channel multiplexing is done through
register 32[5:4]. The default value of 0x0 disables all
channel multiplexing. Higher values sets a higher degree of
channel multiplexing. Note that the Sync identification
codes are repeated multiple times depending on the
multiplex factor. The channels that are used per degree of
multiplexing and the number of Sync Code repetitions are
shown in Table 35. The unused data channels are powered
down and will not send any data.

The image data output occurs through a single 10−bit

No windowing information is sent out by the sensor.

frame is completely transmitted.
The line_valid indication serves the following needs:
♦ While the line_valid indication is asserted, the data
channels contain valid pixel data.
♦ The line valid communicates frame timing as it is
asserted at the start of each line and it is de−asserted
at the end of the line. Low periods indicate the idle
time between lines (ROT).
♦ The data channels transmit the calculated CRC code
after each line. This can be detected as the data
words right after the falling edge of the line valid.

The frame valid indication is asserted before the first black line, but the line valid indication is not
asserted for the black lines. The line valid indication indicates the valid image pixels only. This
mode is useful when one does not use the black pixels and when the frame valid indication needs
to be asserted some time before the first image lines (for example, to precondition ISP pipelines).

In this mode, the black pixel data is clearly unambiguously indicated by the line valid indication,
while the decoding of the real image data is simplified.

that the data channels contains the black pixel data and CRC codes (Training patterns are

When ‘0’, exposure configurations are sync’ed
at the start of FOT. When ‘1’, exposure
configurations sync is disabled (continuously
syncing). This mode is only relevant for Triggered snapshot - master mode, where the exposure configurations are sync’ed at the start
of exposure rather than the start of FOT. For
all other modes it should be set to ‘0’.
Note: Sync is still postponed if
