  • Forum Post: TVP5146 Sync on Green Support?

    Bernie Thompson TI
    Looking at the TVP5146M2 datasheet , it explicitly says that sync on green is not supported, and any references to RGB support refer to SCART, however I do not see this note in the TVP5146 datasheet . Does the TVP5146 (non M2) support sync on green RGB video sources, or is this simply an omission from...

    Yes, the TVP5146 (non M2) supports interlaced RGB with SOG as defined in the SMPTE 253M standard. However, it does not support VESA PC graphics formats such as VGA, SVGA, XGA, etc. Refer to section 2.11.1 and Table 2-12 in the TVP5146 datasheet for information on selecting the RGB input mode.

    Kevin Claycomb
    I have been working with the Davinci DM365 EVM board which has a TVP5146 part for composite video input. The board works great using the standard TVP5146 driver with color cameras, however it fails to auto detect an input when I try to use a B/W camera. These cameras are both NTSC. I have verified with...

    Kevin, Without the color burst, the TVP5146 should still be able to distinguish between a 525-line standard and a 625-line standard. What exactly do you mean by "fails to auto detect"? What standards are selected in the auto-switch mask? Regards, Jim

    This is most likely an auto-switch related issue, if the defualt setting (23h) is not being used in the Autoswitch Mask Registger (Subaddress 04h). The TVP5146 auto-switch algorithm relies on the color burst to disinguish between 525 line video formats. Please try setting REG04h=23h. Alternatively...

    Willl we be able to do the same for PAL as we have a B&W PAL camera? If so, what do we need to change because doing similar changes described for a NTSC above, we get "Lost Lock detect" in Status1 register. On a first fly-by only the color subcarrier lock is indicated as lost lock (status1...

    Jinh, One of the problems I was having was that the autodetect feature was selecting the wrong input so there were three things I did to get mine working, although now my design will only work with NTSC cameras on a single input which is ok for my application. 1. Hard code the tvp514x driver...

    Hi Kevin, being new to linux etc I am still in a bit of a corner hardcoding the driver. I have changed the autoswitch mask but not the input channel as it seems to beOK with the one detected but am unsure about this and left the evm stuff as is so let me know if this is to be done please.

    Maybe just to give more detail on my current debug findings after Bernie on the DM3x forum said I should mention the TVP5146's behaviour here: these are done after changing autoswitch register to 23h and setting mode = PAL: On my debug output I see first round that TVP5146 indicates lost color...

    I found setting to configure the board to pick up black and white video: Change lock_mask from 0x0E to 0x06 in dm365_tvp514x_evm_chan_config in file video_davinci_evm.c. There is not a need to change autoswitch mask or video standard register. Thanks to all for help, Jinh T.

    Hi Larry, it's the Status1 register at 3Ah where it now ignores the ColorSubcarrierLockStatus bit. regards, Jinh T.

    There is a NTSC interlaced video input and should be converted to progressive 4:2:2 YCbCr format. I went through the video decoder chips like TVP5151,TVP5146 but I didnt see that the interlaced input is converted to progressive format in these datasheets.

    Vico, Are you replacing with a TVP5147M1 or TVP5146M1? The TVP5146M1 is not present on the TI website and is not recommended. The only TVP5146M1/M2 difference is firmware and ROM code. There is no difference in I2C hardware. The TVP5146M1 is not recommended and may not be firmware compatible with...

    The I2C resgisters for basic setup are the same. The DM365 driver may report errors if the ROM version in REG 70h is being checked. The ROM version readback will be different for the two devices. If TVP5146M2 firmware patch code was being loaded at power up, this will have to be disabled if the TVP5146M1...
