Product number: TL7051-PK

The TL7051 Dual 3G/HD-SDI Output Video Transceiver module from AIVION connects to the digital video interface (LVDS) of the block camera and supports several progressive and interlace HDTV formats. As no analog to digital conversion is done on these modules, excellent output image quality is achieved.

    Temperature Alert Function

    When board temperature exceeds 80°C (176°F), red LED will be switched on.
    In addition such an event can be signalled on connector J1/pin7 by setting switch 3 (temp alert enable) to ON position. - In case board temperature is equal to or over 80°C (176°F), level on J1/pin7 will be held constant low ( < 0.4V)
    - In case board temperature is less than 80°C (176°F), level on J1/pin7 will be high (> 2.4V)

    Test Pattern Generator

    TL7051 has an integrated test pattern generator (TPG) which can be operated independent of any camera. The TPG can be enabled by setting onboard switch number 4 to ON position and repowering the TL7051 board. In addition one out of two test pattern and one out of four video standards can be selected by setting onboard switches 1, 2 and 3 accordingly. The following tables summarize all details.
    To enable TPG mode, please execute these steps:
    1. Set video mode with switches 2 and 3
    2. Set pattern with switch 1
    3. Set switch 4 to ON to enable TPG mode
    4. Switch TL7051 power off and on again
    Note: TPG operation can be enabled with or without any camera connected to TL7051

    Analog Video Output

    TL7051 provides analog HDTV YPbPr and analog SDTV CVBS video output signals. These signals are directly taken from the camera. In some camera modes no or only limited analog video output might be available. Please refer to the related camera documentation.

    Reset Operation

    When applying power to TL7051, the camera is also automatically powered. During power up all functions on TL7051, are reset and initialized. During operation a manual reset can be applied by pulling pin no. 5 of connector J1 to 0V (GND). This resets also the camera.

    Camera Control

    Camera control can be done by connecting a PC or CCU via RS485, RS232 or serial 3.3V TTL interface to TL7051. The interface is passed through to the camera that all VISCA protocol based software can be used. Serial interface selection must be done be appropriate setting of switch-2.
