Introduction MC130x Users Manual Rev. 2.1
2 Introduction
The CMOS-High Speed camera MC130x is a high resolution c
era with 1280•1024 pixel. Benefits of CMOS technology are high
speed, random access to pixels with free programmability and low
power.
The camera uses industry-standard C-Mount lenses. The sensor
diagonal is 1,25“ with square pixels measuring 12µm.
Free programmability means that the user is free to define the r
gion of interest by size and position and the speed of data output.
With a resolution of 100 x 100 pixel, the frame rate exceeds 4850
frames/sec. The highest continuous data rate at the output can be
constant with a maximum of 132 Mbyte/sec (16Bit data width at
66MHz pixel clock).
The MC130x is configured via a serial interface (MC1300 uses
RS232, MC1301 uses the serial interface according to the Camera
Link specification. There are six configuration parameter sets
(called: profiles) available, one camera profile, four user profiles,
and one factory profile that cannot be modified by the user. All
profiles are stored in non volatile memory.

3 Hardware
3.1 Serial interface
The communication via the serial interface is optional. The camera
was programmed with predefined profiles and is fully operative.
For loading new parameters or settings into the camera a serial data
link is needed.
A description of the connector pinning is in chapter 9.2
3.1.1 MC1300
A connection is accessible via a standard 9-pin or the 44-pin data
connector.
Parameters of the RS-232 link:

Data bits 8
Parity n
Stop bits 1
See chapter 9.2
for pinning and wiring of the RS-232 cable.
.
3.1.2 MC1301
The serial interface is integrated in the Camera Link connection,
which is supported by many frame grabbers. The settings for the
communication are shown in table 3.
12
Hardware MC130x Users Manual Rev. 2.1
3.2 Digital video interface
The digital video interface supplies pixel data (D0...15), pixel clock
(CLKOUT), line- and frame data valid signals (FDV, LDV). Start
and duration of exposure time can be defined with the exposure
input signal EXP.
Pixel data is 8-bit wide (256 grey levels) and two adjacent pixels
are output with one pixel clock. Pixel clock is 66MHz max, all signals change after the rising edge of clock with a hold time of typical 4,5ns (3,5..6ns max). See Pixel clock
Connector pinning is described in Chapter 9.2
3.2.1 16 bit LVDS interface of MC1300
All signals are transmitted with twisted pairs at an impedance of
100Ω, conforming to RS-644 signal definition.
3.2.2 Camera Link interface of MC1301
for details.
.
Camera Link is a communication interface for vision applications.
Up to 28 bits are serialized to 4 output signals, which are t
ted via a RS644 interface using twisted pair wiring and are terminated with 100 Ω.

3.5 Electronic „Freeze Frame“ Shutter
Preceding exposure, the contents of all light sensitive elements is
cleared. When exposure terminates, accumulated charge is transferred to an analog memory associated which each pixel. It stays
there until it is read out (and discharged) by the A/D conversion
cycle.
As all light sensitive elements are exposed at the same time, even
fast moving objects are captured without geometric distortion.

Initial setup MC130x Users Manual Rev. 2.1
5 Initial setup
The MC1300 is delivered with initial parameters and therefore does
not need to be configured via the serial RS-232 link. See the initial
setup parameters in chapter 9.3
5.1 Serial number and firmware revision
Serial number and firmware revision is provided in MC130x non
volatile memory. Use :v command (Read serial number and firm-
ware revision) to read serial number and firmware revision. The
serial number is also marked on the type plate of the camera.
5.2 Camera profile
A profile is the contents of all camera registers and therefore responsible for the cameras mode of operation.
The camera profile is the contents of all camera registers that are
loaded from non-volatile memory after power up. A change of parameters by the serial link is reflected in the camera profile. See
chapter 9.3
for factory setup of the camera profile.
.
5.3 Factory profile
The factory profile can be read but not written by the user. (see
chapter 9.2
18
).
Initial setup MC130x Users Manual Rev. 2.1
5.4 User profiles
The user can store up to four camera profiles in non volatile memory. All load or write commands exchange data between the camera profile and one of the four user profiles.

6 Configuration
The MC130x has 15 FPGA registers, r1..rfh , each 10 bit wide,
eight D/A registers, a1..a8, 8-bit wide, and one clock select register, 4 bit wide.
The contents of all the above registers is called a profile. There is
space in non volatile memory for 6 profiles: one camera profile, 4
user profiles and one factory profile.
Any change of a specific register through the serial interface is
immediately processed and written to the camera profile. This setting is stored in a volatile part of the memory and gets lost when
power goes down.
After power-up the camera profile is loaded from the non-volatile
to the volatile part of the memory and is used to adjust the camera.
A load or write command exchanges data between the camera profile and one of the four user profiles.
The factory profile can be read but not be written by any command.
All values are given in hexadecimal notation, e.g.: 0xff or 0ffh =
255.

6.5 Clock selection
The MC130x is equipped with a 2-channel programmable clock
synthesizer. One channel controls clock frequency of the sensor,
the other controls the frequency of the pixel clock.
26
Configuration MC130x Users Manual Rev. 2.1
For a given data rate on the video output (pixel clock) the ratio of
sensor/pixel clock defines how many pixels out of a line can be
output, while maintaining the highest possible sensor clock
frequency.
For an easy adjustment the speed (sensor and pixel clock) of the
camera may be switched in 16 steps. To get optimized speed selection the frequency steps differ in dependence of the mode (see also
chapter 9.4
Example: Mode 2, frequency step s9
Pixel clock: 27,5 MHz
Sensor clock: 11,2 MHz
Resulting, maximal data rate at the 16 bit output:
27,5 MHz/s * 2 byte = 55,0 Mbyte/s
The clock select command :s selects together with the four cameramodes 48 frequency pairs for sensor and pixel clock.
).
Command :s <x
Before selecting the data rate of the camera check
the maximum data rate of the frame grabber, which
must be higher (or at least the same).

6.6 Camera operating modes
Control register r6 controls camera mode, type of exposure and
exposure time.
The camera mode determines the maximum number of pixel of a
line that can output.
Type of exposure is either synchronous or asynchronous. Synchronous means that image is output continuously. Asynchronous
means that an external signal starts exposure and image output.
Ten exposure times can be selected for asynchronous mode.

6.6.1 Camera mode and maximum line length
To maximize frame rate for a given data rate on the video output,
line length is divided into four steps. Only a fraction of the full line
length is then written to the FIFO of the camera with the selected
sensor clock. Therefore the sensor clock can be higher than the
pixel clock by a factor of 5/line length fraction. Four camera modes

0..3, corresponding to full, ½ , ¼ and 1/8 line length, can be selected from the two most significant bits of register r6.
The maximum line length is also dependent on the pixelbinning
feature. Table 7 shows the relationship. As frame rate is dependent
on image size which is programmable, the frame rate is given as
time for one line.

6.6.2 Type of exposure
The MC130x can expose the images synchronous with or without
an electronic shutter, or asynchronous with a programmable internal timer or by pulse width control of the trigger pulse. Bits 7..4 of
registers r6 define exposure type: (:r6[7..4]).

6.6.3 Synchronous operation without shutter
Without electronic shutter the exposure time depends on the frame
rate. As frame size can be chosen arbitrarily, the frame rate can be
calculated from the time per one line (see Tab. 5).
6.6.4 Synchronous operation with shutter
In the sensor is implemented a freeze frame shutter, which allows
to reduce the exposure time in steps of one line.

timer. The least 4 significant bits of r6 define exposure time.
6.6.6 Asynchronous operation, shutter control by timer
This operating mode is selected with register 6:

6.8 Firmware
6.8.1 Update Firmware
MC130x’s logic is integrated into a FPGA (field programmable
gate array), which’s configuration is stored in an EEPROM. Upon
power up or a command the FPGA is loaded with this configuration. Configuration data can be downloaded via the serial interface
(RS-232 for MC1300, serial interface of Camera Link for
MC1301). Mikrotron provides configuration files (*.ibf) on request.
Example for the download procedure of configuration data files
using DOS:
Camera is powered up, both LED are on, the serial RS-232 link is
connected
1. Init COM1: mode COM1: 96,n,8,1
2. Copy *.ibf file to COM1: copy mc0120.ibf com1: /b
To configure the FPGA, camera must be powered down/up or the
command :c (see 6.8.1
Download of *.ibf file via serial link takes app. 1.5 min.
There should be no loss of power or communication
during this time!

6.12 Pixelbinning
High frame rates result in short exposure times and therefore need a
lot of light to get bright images. In addition the field of view gets
smaller.
Pixelbinning adds the grey values of two adjacent pixels and outputs it as one pixel with double sensitivity. In X-direction only 512
pixels are needed to cover the sensors full size. To retain aspect
ratio, every second line is omitted.
Command: :r7010

6.14 Image counter
If a sequence of frames is to be recorded for long time at a high
frame rate, it can be useful to mark the images for later identification or check for completeness.
MC130x has a 16-Bit image counter whose count can replace the
first two pixel of every image. The image counter is cleared with
every low to high transition of r6[4], the camera enable bit. It is
incremented by every new image.
6.15 ImageBLITZ shutter release
ImageBLITZ can replace an external signal (e.g.: a light barrier) to
release the shutter. Like a light barrier, ImageBLITZ is used to capture fast moving objects on the exact same position on the image.
Contrary to the light barrier, ImageBLITZ uses the same information as condition to release the shutter as the then exposed image.
37
Configuration MC130x Users Manual Rev. 2.1
ImageBLITZ defines one specific line or a part of the 1024 lines as
trigger window. This is true even if the selected image size is less
1024 lines or outside of the selected image area.
After activation of ImageBLITZ and after issuing the EXP signal as
an enable signal, the MC1300 hardware checks the grey values in
the trigger window at a repetition rate that is defined by the exposure time selected with bits 3..0 of r6.
If a selectable number of pixels along that trigger window exceed
or fall short of a selectable threshold, one single image is exposed
and output.
To adjust ImageBLITZ®, the trigger line can be superimposed to
the image. Within the selected line, 10 pixel are displayed as a dotted black- and white line as long as the selected threshold is not
passed.
ImageBLITZ is configured with the registers r8..rC

6.15.1 ImageBLITZ® processing
When ImageBLITZ® is activated and an active transition of the
EXP input has once occurred, the following cycle is repeated:
1. MC130x Hardware checks at a repetition rate defined by
the inverse of exposure time (:r6[3..0]), the intensity of a
group of 10 pixel along the selected trigger window are
compared against an adjustable threshold (:rA

Range: 255..0).
38

h
second threshold (:rB
[6..0], Range: 127..0).
h
3. Each time this threshold is exceeded (release condition); a
line counter (:rB
[9..7], Range 0..145 in 8 steps) is loaded.

and output.

When reading a camera profile with the :w command, some return
values differ from the input values. While clock frequencies are
selected via the :s command from a table within the microcontroller, the return value are two actual hexadecimal codes used to program the cameras synthesizer. See: Code for Clock Synthesizer

9.4 Camera clock, frequency selection
The MC130x operates with two clocks: the sensor and the pixel
clock. The sensor clock runs the sensor and thus defines the
cameras data rate. The pixel clock is responsable for the data rate
on the LVDS output. The ratio of both frequencies differ according
to selected camera mode. See: Camera mode and maximum line
length. All frequencies are selected from an internal table with 4 x
16 entries. These are 4 camera modes x 16 select codes, 0..f
command :s<x
>, see chapter 6.5
0
The pixel clock is only dependant on the select code <x
sensor clock is dependant on the camera mode and select code.
Example: Camera mode 3, selection 4:
Sensor clock = 3 MHz
Pixel clock = 15 MHz
Table 19 shows the selectable frequencies, table 20 shows the
programming codes that will be returned as a result from the :w
command.
