  • Forum Post: TVP5150 video decoder in non-standard application

    Dave Jones
    I need to lock to a standard definition video signal (NTSC or PAL) and generate a line locked pixel clock, H sync, V sync, composite blanking and color subcarrier. The TVP5150 looks like it can do all of that except recreating the color subcarrier. I can not find any chips in current production that...

  • Forum Post: TVP5150AM1 no NTSC colour lock

    David Ambry
    Hi there, My TVP5150AM1 application does not colour lock on NTSC, but does on PAL. Luminance is always correctly decoded. Sometimes Pr is correctly decoded, but in that case there is no Pb. Some background information: The device is clocked from the crystal output of a 3.3V 8051-family...

  • Forum Post: Re: Line ID - An issue about TVP5158!

    Viet Dinh
    Leon, The line ID can be larger or smaller than standard number of line if: The input signal is non-standard The input is pulled in/out when it is in the middle of the field. The line count does not reset until it detects a vsync. So, the backend can ignore the line ID that is greater than...

  • Forum Post: Re: TVP5158 loss the sync when IR camera is used and turn on IR lamp

    Viet Dinh
    SI, To check for the patch download correctly, you can read the RAM Version (register 05h) and RAM Test Version (register 06h). For example, if the patch is 02.01.17, you should get 01 for register 05h and 17h for 06h. We will try the sync loss in lab. Regards, Viet

    Dear Viet, The register 8Ch is 83h(Autoswitch mode and (B,G,H,I,N)PAL ITU-R BT.601). By the way, the Status register #1(address 88h) value is read 6Eh or EEh(Peak white is detected or not). Especially the picture such as posted in my previous question, EEh is read more frequently than...

    Tetsuro Fukuhara
    Hi, Is there an official TVP5151 migration note from TVP5150AM1 for customers? May I say the customer can simply replace them on their current TVP5150AM1 boards without any register setting changes? Best regards, T. Fukuhara
