ADV7343 Video Input Resolution

Hi,

 ADV734x can support 640x480 8-bir RGB input to CVBS output. Refer Table 1 in ADV734x datasheet

 NTSC which has total lines of '525' interlaced & 640 x 480 refers to an active pixels.

Thanks,

Hi, 

Thanks for reply, I edited my question later, my image format is 640x480 12-bit monochrome or 640x480 8-bit monochrome.

I can't see any information about monochrome input. Can ADV7343 support monochrome input?

Thanks.

Hi,

   Yes, ADV734x can support monochrome input.

   Please try to set the SD Burst and SD Chroma = 1 to disable the burst 

   Disable the SD burst - 0x84[5] (no color burst => no color) and disable the chroma channel 0x84[4]

Thanks,

Poornima

Hi,

Thanks for reply.

For 640x480 8-bit monochrome input can I use following picture part (NTSC square mode 8-bit EAV/SAV YcrCb).

For 640x480 12-bit monochrome input what should I do?

Best Regard.

Hi,

  When refer the ADV734x datasheet, 12 bit configuration is not available so you can configure only 8/16/24 bit depth for SD/ED/HD modes.

Thanks,
