3 CLS-16k Release Notes Thank you for purchasing the CLS-16k Digital Camera from illunis. The CLS-16k camera uses the latest technology, which includes Camera Link (CL) with the following notes: CLS-16k camera supports two readout modes. 1. Camera Link Single: By using a single Camera Link full interface, the data is output as 8 taps separate, from left to right. In this mode, the camera will run 36k lines per second. 2. Camera Link Full: By using two Camera Link full interface s, the data is output as 8 taps separate, from left to right on each interface. Two Camera Link full interfaces are required, one capturing the left half and one capturing the right half of the image. In this mode, the camera will run 77.8k lines per second. CLS-16k camera supports calibration features which include: 1. DSNU: Dark Signal Non-Uniformity: This corrects the black level. 2. PRNU: Pixel Response Non-Uniformity: This corrects the bright level.

Software can be downloaded at: For more information please call illunis at (952) or 1.2: CLS-16k Overview Warranty Warranty. Please review the standard illunis warranty at: Returns. Products will be considered for replacement for up to one year from the date of shipment. All returns require a RMA number. No returns will be accepted without a RMA number. Returns will be re-tested against the device acceptance criteria. If the hardware is found to meet those criteria, it will be shipped back to the customer at the customer s expense. Please contact: info@illunis.com to request a RMA Number. 1.3: CLS-16k Overview Compliance The CLS-16k camera is tested to comply with the following: FCC CE CLS-16k Operations Copyright illunis, LLC 6/3/2016 Page 14

15 1.4: CLS-16k Overview Power Consumption The CLS-16k camera can operate in the following modes with estimated power: The CLS-16k is available in two versions, with and without LVDS Pre Emphasis drive. LVDS Pre Emphasis is an output overdrive technique that compensates for HF cable losses and extends transmission distance. It effectively increases the usable Camera Link cable length to 10M or more. The down-side is that the Pre Emphasis drive requires significant additional power. The standard LVDS output drive has the advantage of significantly lower power consumption and correspondingly heat generation at the disadvantage of shorter cable drive. The default CLS-16k is configured with Pre Emphasis drivers and at the maximum clock rate of 85Mhz. Please contact for other versions and clock speeds. CLS-16k Camera Versions LVDS Drive Pixel Clock Lines Per Second CL Full Max Cable Length (estimated) 12VDC Pre-Emphasis 85Mhz 76.3k ~10M <15W Pre-Emphasis 60Mhz 53.8k >10M <15W Standard 85Mhz 76.3k >5M <5.4W Standard 60Mhz 53.8k >7M <5.4W 1.4: CLS-16k Overview Sensor Defects No dead or stuck pixels are allowed.

22 2.3.1: Hardware Camera Link Cables The CLS-16k camera uses Camera Link standard cables. The camera end of the cable is the SDR female connector. illunis recommends using the following link to configure and purchase these cables ( The following 5M cable configurations have been tested and are supported. Each Full Mode: Standard MDR: MVC M Note: The user must verify that the cable selected can operate at 85Mhz speed in order to use the full bandwidth of the Camera Link Base/Medium interface. CLS-16k Operations Copyright illunis, LLC 6/3/2016 Page 22

23 2.4: Hardware Considerations Do not open or disassemble the camera case or electronics as there are no user adjustments within the camera. This will void the warrantee. Care must be taken in handling as not to create static discharge that may permanently damage the device. Do not apply power with reversed polarity as this may render the camera non-functional and will void the warrantee. Camera Link is a DC based interface. The camera and capture device must share the same electrical ground. Failure to do so will destroy the Camera Link interface chips and/or camera and capture card. Absolute Maximum Ratings Input Voltage: 10 to 18V DC Storage Temperature: -40 C to +70 C Recommended Maximum Ratings Input Voltage: 11 to 14V DC Operating Temperature: 0C to +60 C Most illunis cameras operate beyond these temperature limits, please call for details. Recommended Operating Conditions Input Voltage: 12V DC Operating Temperature: 0C to +60 C Relative humidity should not exceed 80% non-condensing. Thermal Interface The CLS-16k camera contains many advanced circuits and performs at high clock speeds and thus requires careful consideration for thermal cooling. The camera should be used either with a lens and/or a solid mechanical mount that acts as a heat sink. Power Consumption The CLS-16k camera was designed to be as small as possible and as such has a high energy density. The various operating modes of the CLS-16k will change the power consumption from the base line. In particular, the dual output and Pre Emphasis Modes require more power. The Triggered Modes are lowest in power when the camera is waiting for a trigger. Special versions of the CLS-16k with lower clock speeds are available with lower power consumption.

27 3.0: Software ICD Overview The CLS-16k software interface (commonly called an Inter-Connect-Description or ICD) was developed for high reliability applications. The ICD incorporates error checking and a handshake protocol, which responds with either a positive or negative acknowledge signal. The communication path from frame grabber to the CLS-16k is through the Camera Link cable. The CLS-16k microprocessor is a flash programmable device with many features vital to the operation of the CLS-16k camera. Some of these features include: Hardware UART used for serial communications. A watchdog timer used to monitor communication errors and system faults. Onboard RAM and EEPROM for saving camera settings. Brown out detection and reset. 8 configuration storage areas. 0 = Factory, 1-7 User Communication (and trigger) can be on either the A or B port. (USE ONLY ONE PORT) The camera auto switches from one port to the other at the beginning of a command Only one port can be active at a time. Command with checksum Camera Data and/or ACK/NACK Capture Device 3.1: Software ICD Serial Interface SERIAL INTERFACE PROTOCOL Implementation Camera communication is accomplished via asynchronous serial communication according to EIA Standard RS 232 C through the Camera Link cable. Data rate: Full Duplex, 115,200 baud. 1 START bit. 8 DATA bits The LSB (D0) is transfered first. 1 STOP bit. No parity. CLS-16k Operations Copyright illunis, LLC 6/3/2016 Page 27

28 Protocol 3.2: Software ICD Command Packets The CLS-16k camera is controlled through command packets. The CLS-16k camera is considered a slave device and never generates data without a read request. The data packet formatting is described in detail below. Note: the checksum is calculated only on the 4 ascii characters comprising the Data. Data Packets Data packets are of either read or write types. For example: to read the camera serial number, the packet sent to the camera would be {r fe}. The camera would respond by issuing an acknowledge character! followed by the response {r0700sssscc}, where ssss is the camera serial number and cc is the checksum calculated in hex as 0x0100 ( ss (high byte hex) + ss (low byte). Packet Format 1 Char 2 Char 2 Char 2 Char 4 Char 2 Char 1 Char 1 Char Start Command Target Index Data Checksum End Ack/Nack Start: Indicates the Start of the frame Size = 1 ascii character Value = 123 Decimal (ascii { ) Command: Command descriptor Size = 1 ascii character Value = 114 Decimal (ascii r ) for Read Value = 119 Decimal (ascii w ) for Write Target: Command descriptor Size = 2 ascii characters Index: Command descriptor Size = 2 ascii characters Data: The data transferred Size = 4 ascii characters Checksum of Data only (default) Size = 2 ascii characters - Intel-Standard - two s compliment of sum of data. Example 3: Data = fef0, checksum = lower byte of (0x100 (0xfe + 0xf0)) = 0x12 Checksum of Command and Data: checksum( comandindex ) + checksum( data) End Example 4: Command = 0400, data = 0x0001 (0x100 (0x04 + 0x00)) = 0xFC (0x100 (0x00 + 0x01)) = 0xFF Checksum = lower byte of 0xFC + 0xFF => 0xFB Indicates the End of the frame Size = 1 ascii character Value = 125 Decimal (ascii } ) Ack/Nack Positive acknowledge - Negative acknowledge Size = 1 ascii character Ack Value = 33 Decimal (ascii! ) Nack Value = 63 Decimal (ascii? ) Example 1: Data = 2002, checksum = lower byte of (0x100 (0x20 + 0x02)) = 0xde Example 2: Data = 0000, checksum = lower byte of (0x100 (0x00 + 0x00)) = 0x00 COMMAND DESCRIPTIONS Read Command Structure The CLS-16k camera parses the sequence byte by byte. An invalid read command, target, or index will cause the camera to issue a NACK. The Host (the user) will generate dummy data with a valid checksum then an end. The camera will respond with an ACK and re-send the command with valid data and checksum. If the Host detects an error, it will re-issue the command. Host {r tt ii cc}, camera issues! Camera issues {r tt ii data data data data cc} (NOTE no ACK). Write Command Structure The CLS-16k camera parses the sequence byte by byte. An invalid write command, target, index, or checksum will cause the camera to issue a NACK; otherwise, the write sequence will complete and the camera will issue an ACK after the command has been executed. The camera receives the checksum from the Host. Host {w tt ii data data data data cc} camera issues! Error Checking The CLS-16k camera parser is character by character and will respond with an immediate NACK if any unrecognized command, target, index, or checksum occurs. Communication Timeouts The CLS-16k camera micro-controller uses a hardware watchdog timer that will time out if the time between bytes are longer than???ms. When sending command frames to the camera, the Host must not have significant delays between bytes sent. CLS-16k Operations Copyright illunis, LLC 6/3/2016 Page 28

41 4.0: Image Exposure Overview The CLS-16k camera can be programmed to expose images in either Free Run Mode or Trigger (sync) Modes. The Free Run Mode outputs lines continuously by using a pipelined global shutter for exposure. The Trigger Modes synchronize the camera exposure to an external signal, within the limitations of the line and exposure time timing. The camera outputs lines at a programmable line rate, with the following limits: Exposure >= 1 us Exposure < Line Period - 3us Line Rate (Hz) = 1 / trigger period Pixel Clock = 80Mhz or 60Mhz Pixel Clock Period = 1/Pixel Clock Maximum line period = Pixel Clock Period * 65,535 The exposure modes are as follows: Free Run Mode: Camera continuously outputs lines based on the line time. Exposure is set with the Set exposure register. If exposure time > line time then exposure time sets line rate. Triggered Program: Camera outputs lines according to CC1 (Camera Link). Exposure is set with the Set exposure register. Minimum and Maximum exposure limits are valid. Exposure starts ~1.5us after trigger rising edge. Triggered Manual: Camera outputs lines according to CC1 (Camera Link). Exposure is set with the active pulse width. Minimum exposure lit is valid. Maximum exposure is trigger pulse width. Exposure starts ~1.5us after trigger rising edge. Exposure stops ~ 0.25us after trigger falling edge. CLS-16k Operations Copyright illunis, LLC 6/3/2016 Page 41

48 The CLS-16k sensor implements a dual column readout architecture where the odd pixels are read from the top of the sensor and the even pixels are read from the bottom of the sensor. Each path implements independent analog gain and offset. The analog offset and gain increase with register value (opposite of internal register settings). The analog gain can be programmed in a range of 6dB to +20dB in 255 steps. The settings in the analog gain and offset registers are critical for balancing the odd/even column outputs (before the DSNU/PRNU are applied). An additional CDS programmable gain stage is provided that applies 1X or 4X analog gain. The main advantage of this gain stage is that the 4X gain is applied with only a 2X increase in noise. It is recommended to use this gain stage before applying the analog gain. The possible (gain) range with both stages is 0.5X to 40X analog gain. The ADC operates in a 10 bit mode and the output data is formatted for the internal data path.

Of the 13 bits of ADC data only 12 are usable. The internal data path of the CLS camera uses all 12 bits of image range. For high speed imaging the CLS camera must be limited to 10 bits of ADC range. Of the 10 bits of usable data only 8 bits are output from the FPGA as Camera Link data.

50 5.3: Image Processing DSNU: Dark Signal Non-Uniformity Dark Signal Non-Uniformity (DSNU) Correction is used to correct for dark field offset within the sensor. The dark-signal itself can be composed out of: 1. a thermal component, which will depend on the temperature and the exposure time. The thermal component will be present on pixel level. 2. an electrical component, which is independent on the exposure time and almost independent on the temperature. This electrical component is due to threshold variations, gain variations, and other imperfections in the electronic circuits. In a linescan camera, this is present on a column basis.

51 5.4: Image Processing PRNU: Pixel Response Non-Uniformity Photo Response Non-Uniformity (PRNU) is used to correct the difference in pixel response and the change in response due to optical or light source differences. The sensor signal is composed of: 1. DC offset, introduced by the electronic circuitry, and which is independent of temperature and exposure time. 2. dark current, depending on temperature and on exposure time. 3. photo response, depending on exposure time.

61 7.0: Camera Link Overview Camera Link is a communication interface for visual applications that use digital imaging. The Camera Link (CL) interface is built upon the National Semiconductor Channel Link technology and specifies how image data is formatted and transferred. Channel Link consists of a driver and a receiver pair. The driver accepts 28 single ended data signals and a single ended clock. The data is serialized 7:1 and the four data streams and a dedicated clock are transmitted over five LVDS pairs. The receiver accepts the four data streams and the clock, decodes the data, and drives the 28 bits of data to the capture circuit. Image data and image enables are transmitted on the Camera Link bus. The four Enable signals are: FVAL: Frame Valid is defined HIGH for valid lines. LVAL: Line Valid is defined HIGH for valid pixels. DVAL: Data Valid is defined HIGH for valid data. SPARE: undefined, for future use. Four LVDS pairs are reserved for general purpose camera control. They are defined as camera inputs and frame grabber outputs. The signals are CC1, CC2, CC3, CC4. The CLS-16k uses CC1 as the trigger source. The Camera Link interface has three configurations: Base: Medium: Full: Single Channel Link chip, single cable connector. Two Channel Link chips, two cable connectors. Three Channel Link chips, two cable connectors. Note: CLS-16k operates in a single or full Camera Link mode CLS-16k Operations Copyright illunis, LLC 6/3/2016 Page 61

62 7.1 Camera Link Pixel Format The CLS-16k camera samples the sensor with 12 bit precision and processes the data throughout the FPGA at 12 bits. During the data format stage, the 12 bit image data can be down sampled to 8 bits. In addition, the bottom 8 bit data can be output as the top 8 (msb) of the 12 bit image sample. Quick FAQ s: Sensors rated at 60dB SNR have about 10 clean bits (dynamic range). 8 bit pixel data is packed in single bytes; therefore, requires 1/2 the system bandwidth that the 10 and 12 bit formats require.
