TVP5146M2: TVP5146M2 output 8-bit instead of 10-bit

Hossam Moghrabi

Part Number: TVP5146M2

Hello

I would like to get TVP5146M2 to convert analog rgb, ypbpr, cvbs, s-video to digital output which is 8-bit not 10-bit since my DAC (ADV7343) accepts 8-bit only.

I noticed that TVP5146M2 has 8-bit mode but could not find it in registers, so please help me on this. I know support is limited on this but I won't need much support, just fast and small one.

also, what is the maximum resolution it can handle?

thanks

    Hello Hossam,

    Unfortunately for this product it isn't limited but no support. We do not have the technical expertise to answer these kinds of questions in detail.

    For 8-bit operation I think your best bet would be to connect the upper 8-bits of the output to your DAC. I cannot find anything about 8-bit mode either and have no idea why that is mentioned.

    I don't know what this correlates to in terms of max resolution but I did find this about resolutions: The TVP5146M2 supports interlace RGB inputs having standard 480i or 576i component video timing.

    I would presume that means the maximum resolution of 576i is the upper limit.

    Unfortunately that's the extent of the answers I can provide for this.

    Best Regards,
