    Hi Nick, To guard against potential noise issues, our preference would be to not sacrifice the RCA>TVP5146 analog trace lengths. We have freqeuntly connected the TVP5146 digital outputs to other boards using both connectors and cables while operating at full 27MHZ 10-bit BT656 speed without problems...

    Hi Nick, The frame cannot be inverted by the TVP5146. This would have to be done by the processor after frame capture.

    Vsevolod, Your settings are for composite video on the VI_2_B TVP5146 input. Is your system set up to convert 10-bit 4:2:2 YCbCr data to RGB? The TVP5146 output will be 4:2:2 YCbCr. Do you see any changing video from the camera? What video test pattern Is being used when you see the green...

REG 03h = 01h REG 03h = 00h // Toggle Power save bit after power up REG 00h = 05h // Input MUX, CVBS input connected to channel...

    Hi, I get these frames: Now TVP has minimum settings. These green lines (on the black) and purple lines (on the white) relate to settings of TVP? Why I can get frames 2 in 1? Thanks.

    Jamal, You may want to look at some of the DM video processors such as the DM6467. These parts are used with anlog front-ends such as the TVP7002 (HD component and graphics support) an TVP5146/7 video decoders (SDTV and composite video support). HDMI can also be supported. EVM schematics should be...

    Nick, If separate HS,VS,FID, and AVID syncs are being used instead of embedded syncs present on Y[9:0], the same precautions should be taken with these signals to maximize setup/hold timing margin.

    Hello Jack, The TVP5146M2 supports interlaced RGB component video as defined in the SMPTE 253M standard. The TVP5146M2 does not support VESA PC graphics formats from a computer’s VGA port. Regards, Viet

    Hi All, I would like to ask a question on capacitor connection for TVP5146. In the page for TVP5146M2 connection, found in EVM6437 schematics , capacitor C294 is with a plus symbol. What does the plus symbol mean? I also noticed that its footprint in PCB is quite different...

    Zheng, The schematic symbol was for a polarized cap ( tantalum, electrolytic type), whereas the board may have actually used a ceramic non-polarized type. The "+" and cap orientation is only important if polarized caps are used. The 10uF cap is larger, so a larger footprint is used. It is...

    Dear Larry, Briefly and the most importantly, what is the difference between polarized and non-polarized type? There must be a reason for using polarized capacitor, so doesn’t it matter (any adverse effect: noise, etc.) if the board replaces it with a non-polarized type? Zheng

  • Forum Post: Re: Question on a TVP5150 capacitor

    Larry Taylor
    Unpolarized, like ceramic, is typcially limited to smaller capacitance values. Larger capacitance values are typically polarized, like tantalum and electrolytic. 10uF is near maximum for ceramic type caps. A 10uF ceramic cap may be physically smaller than a polarized cap but may be more expensive. In...

I want to use this setting, but I set this seeting on my tvp5146m2, no effect on the video. The ROM Version of my chip is 8.00 ( 70H = 0x08, 81H = 0x00 ), I think...

    Hi, We have a design based around TVP5146M2 and the video input format is CVBS PAL.
