ADV7482 for BT656 to MIPI CSI-2 input

Hi,

I am searching a chip to convert 1280x720, 30fps BT656  signal to MIPI CSI-2 interface.

Can ADV7482 do the conversion?

Thanks!

    Hi,

    ADV7482 has three different input options :
      Analog video -> BT.656 -> MIPI CSI-2
      8 bit TTL (BT.656 ) -> MIPI CSI-2
      HDMI -> CEA 861 -> MIPI CSI-2
    Also note that the MIPI CIS-2 link retains the line and frame timing of the ITU656 specification
    Please refer Table 79. Resolutions and Formats Supported on CSI-TXA in 1-Lane Output Mode,
    Table 80. Resolutions and Formats Supported on CSI-TXA in 2-Lane Output Mode,
    Table 81. Resolutions and Formats Supported on CSI-TXA in 4-Lane Output Mode.

    Note : The ADV7280-M, ADV7281-M, ADV7281-MA, and ADV7282-M video decoders output video over the MIPI CSI-2 stream.
    However, the video timing is based on the ITU-R BT. 656-3 or ITU-R BT.656-4 standard.

    Thanks,

  • Let me re-confirm: ADV7482 can have 8 bit TTL ( BT.656 ) input and transfer it to MIPI CSI-2 Output? 

    Meanwhile the output resolution and frame rate have to be the same with the BT656 input?

    Appreciate for your quick response.

      Yes,Please refer below

     

    ADV7481 features an 8-bit digital input/output port, supporting input and output video resolutions up to 720p/1080i in both the 8-bit interleaved 4:2:2 SDR and DDR modes.

    Also please refer Table 79, 80 and 81 of ADV748x hardware manual  to know about the supported input/output formats.

    Meanwhile the output resolution and frame rate have to be the same with the BT656 input?
      ADV7480 doesn’t have a frame rate converter or a scaler.

    Note: The ITU-R BT.656-4 standard bit allows the user to select an output mode that is compliant with either the ITU-R BT.656-3 standard or the ITU-R BT.656-4 standard.
    Interfaces for digital component video signals in 525-line and 625-line television systems operating at the 4:2:2 level of Recommendation ITU-R BT.601.

  • Thanks for your answer. 

    Can you tell me where to download the detail Hardware Manual file? I can only find the simple datasheet and cannot see those detail table.

    By the way, is it possible to do the color space conversion ( RGB-> YUV or YUV-> RGB) between HDMI-in and MIPI output?

    Hi,

    Please find the hardware manual from 7026.ADV748x_Manuals.zip  at  ADV7482 Design Support Files

    Note : The CSC in the CP block provides any-to-any color space conversion support. It supports formats such as RGB, YUV, and YCbCr.

    Thanks,
