Filled in software signal names in GPIO table.

  • Page 3: Overview

    Describes power requirements, thermal management, interface specifications, and connector pinouts for the 1500-OEM video processing board.  CAUTION: Any customer modifications to SightLine OEM and adapter boards will void the warranty and can potentially damage the board. Before attempting any modifications, please contact Support. Additional Support Documentation...

  • Page 4: 1500-Oem Specifications

    The USB communications interface is not currently available. Use of this feature is contingent on software updates. Interface Protocol The 1500-OEM shares the same interface protocol as other SightLine OEM platforms. The protocol is a packet-based command and control interface (IDD). The protocol document is also available as a PDF from the SightLine website.

  • Page 5: Functional Block Diagram

    The 1500-SOM is the smallest form factor option to incorporate SightLine video processing functions into customer designs. Access to reference design files for 1500-SOM carrier board (1500-OEM board) is provided under the terms of a simple Hardware Design IP Agreement document. Contact Sales for more information.

  • Page 6: Gap Filler (Thermal Grease)

     CAUTION: On some interfaces, e.g., 1500-Sony / Tamron board, power to the 1500-OEM board is provided through J4 on pins 48 and 50. In these cases do not apply power to J3 pins 8 and 9. Powering the OEM through the J3 power pins and through the J4 power pins can damage the OEM.

  • Page 7: Analog Video Input

    The 1500-OEM uses the embedded Ethernet approach. This consists of 0.033uF capacitors placed in series on the Ethernet lines (AC coupled) onboard. There are no Ethernet magnetics on the 1500-OEM. If the distance is less than a few meters and there is a common ground, there should not be any issues with Ethernet connectivity (even in EMI testing).

  • Page 8: Connector J4

    Digital Camera, Serial Ports, GPIO, Alternate Input Power. This connector is designed to allow the 1500-OEM to mate with the FLIR Tau 640 or other SightLine system interface boards. This is a generic camera input supporting up to 12-bits video data. The 1500- SOM can accept many types of digital video input.

  • Page 9: Internal Pullup On J4 Pins

    On Rev E boards use an adhesive to hold the microSD card in place to prevent ejection during hard aircraft landings or other shocks to the board. MicroSD Card RTV Silicone Adhesive (Locktite 51387 or similar) Figure 4: Example - 1500-OEM (Rev E) Adhesive Placement on MicroSD Card © SightLine Applications, Inc.

  • Page 10: Additional I/O

    IMPORTANT: Do not apply power to both J3 and J4 pins at the same time. On some interfaces, e.g., 1500-Sony Tamron board, power to the 1500-OEM board is provided through J4. In these cases, do not apply power to J3. Powering the OEM through the J3 power pins and through the J4 power pins can damage the OEM.

  • Page 12: Test Points

    Note  IMPORTANT: It is not necessary to apply power to VIOSEL when using a SightLine accessory board other than 1500-AB development board that implements serial 1 and/or serial 2. These boards have a DC-to-DC converter that provides 3.3V to VIOSEL. Powering VIOSEL through both the internal regulator and an external source can have unpredictable results and potentially damage the OEM and accessory boards.

  • Page 13: Digital Video Input Description

    7 Digital Video Input Description Overview The 1500-OEM has a single 16-bit digital video input port - Cam 2 (Digital). The signals are parallel digital video only. (Also referred to as CMOS video.) Signal locations are detailed in...

  • Page 14: Synchronization Signals

    1500-OEM. For 720P60 or 1080P30 cameras in this case, the input pixel clock to the 1500-OEM CAMPCLK will be externally doubled to 148.5 MHz. This does not apply to camera data provided through Sightline adapter boards since these boards implement this pixel clock doubling where necessary.

    The same camera, when configured for different resolutions, can have different vertical and horizontal blanking values. Refer to the camera specific technical documentation for the correct settings. Figure 5: Vertical and Horizontal Blanking © SightLine Applications, Inc.

  • Page 16: Removing Blanking Lines And Pixels

    ICD-1500-OEM 7.8.1 Removing Blanking Lines and Pixels Blanking lines and pixels should be removed when the video is acquired by the 1500-OEM by manually enter the Vertical and Horizontal Front Porch settings. Vertical and Horizontal Front Porch Example (manual blanking entry) Set the Vertical Front Porch (vertical lines of blanking) to 45.

  • Page 17: Appendix A - Missing Driver Chip

    Figure A1: U7 Driver Chip Location Appendix B - Anti-Alias Filter The 1500-OEM does not have an anti-aliasing filter, however if aliasing noise is observed, an anti- aliasing filter has been shown to be beneficial in improving video quality. Figure B2 shows the recommended location of anti-aliasing filter input circuit.

  • Page 18: Appendix C - Analog Video Noise Shielding

    Twisting the analog video VIDEOIN0 and analog ground AGND wires on the input to the 1500-OEM can be effective. In the example setup shown below, shielding was done by twisting the two wires in the center without detaching the pins from the connectors. Also try to keep the two wires away from noisy sources, i.e., the white flat cable carrying digital video.

  • Page 19: Appendix D - Level Translators

    Recommended Level Translators SightLine recommends customers use low-impedance output, unidirectional buffers for their applications. Level translators that use a direction pin to set the direction are also suitable, provided they have a low output impedance and high input impedance.

  • Page 20: D4 Example: Driving A Bob-12009 With Txb0104

    When HV_IO is low, the body diode of the mosfet will pull LV_IO down until the mosfet starts conducting and then pulls LV_IO further down. It is important to note that there are some situations where the outputs are being set by a 10kΩ resistor instead of a low-impedance source. © SightLine Applications, Inc.
  • Page 21 It is easy to see how this problem could be resolved by using a low output impedance, unidirectional buffer. This would reduce R_internal to ~0Ω. It would also be easy to sink the >1mA current from the two pull-up resistors. Figure D3: Equivalent Circuit Seen by HV_IO © SightLine Applications, Inc.
