TMS320DM8146 DaVinci Digital Media Processor + analog video input

Other Parts Discussed in Thread: TVP7002, TVP5150, TVP5146, TVP5147, TVP5150AM1

I am using TMS320DM8146 DaVinci Digital Media Processor and I wish to create a analog video input (for PAL, NTSC input) so as to connect a analog camera to it.

There is digital video input for 8146 so I need to use Video ADC to convert analog video to digital video. Is that right? What video ADC is suitable for connection?

Is there any evaluation board with analog video input that I could buy?

Hi,

You are correct, you will need external ADC to convert into digital video. You can use TVP5146/TVP5147/TVP5150 video decoder for SD video or TVP7002 for HD video.

Thanks,

I realize that the TVP5146/TVP5147/TVP5150 are not recommended for use. Instead, we should use TVP5146AM1/TVP5147AM1/TVP5150AM1 although they are not the same exact replica of TVP5146/TVP5147/TVP5150.

I guess that for SD or HD video, it is dependent of the camera resolution, right?

Hi,

EIO Expansion board is available for TMS320DM8146 with TVP5147 and TVP7002 inputs for SD and HD resolutions respectively. You can get this board and can have analog inputs fed to the capture.
