Customer interested in ADV7401/ADV7441A used for RGB to YUV conversion;


Some questions, would you please help to answer?

  1. If ADV7401/ADV7441 can support input signal is RGBVH and output signal is YUV 4:2:2(8bits data +VH+PCLK)?
  2. ADV7401/ADV7441 can supports RGB input resolutions up to 1280 × 1024 @ 75 Hz (SXGA), what is the highest resolution supported?
  3. Would you please provide the 16-bit 4:2:2 YCrCb timing diagram?
  4. In ADV7401 datasheet, see the red words ,does ' all standards' mean  525i, 625i, 525p, 625p, 720p, 1080i,  1250i, and many other HD and SMPTE standards? Besides what is difference between SDR and DDR?

Single data rate (SDR) 8-bit 4:2:2 YCrCb for 525i, 625i
Single data rate (SDR) 16-bit 4:2:2 YCrCb for all standards


Thanks a lot.
