Hi,
I am using IMXRT1176 microcontroller from NXP. I used ADV7280-M PAL/NTSC video decoder from Analog Devices a while ago. I struggled to get PAL video from that decoder IC for some time but not success. Later I opened several tickets to NXP forums to get an idea why I could not get video. To find the problem cause, I bought an evaluation board, IMXRT1166 from NXP, and OVP5640 digital camera sensor with it. I noticed that I can easily get video data with OVP5640 as RGB565/YUV422 output over MIPI bus but somehow not ADV7280-M.
After a while, I realized that IMXRT1176 MIPI-CSI2 Peripheral Bus does not support ITU-R.BT656 protocol. Since ADV7280-M is transmitting our active video data within CCIR656 protocol, NXP IMX1176 was not aware of that protocol over MIPI bus.
Because of the above reasons, I searched another PAL video decoder ICs. I found TW9992 from Renesas. At first glance, It meets our needs. However, as I mentioned above, because of the struggle for some time with ADV7280-m, I would like to be exact sure that TW9992 suits for us.
Does TW9992 give video data output the same format as OVP5640 camera does over MIPI bus? OVP5640 can give it directly as RGB565/YUV422 format over MIPI bus. I mean Can TW9992 give RGB565/YUV422 within ITU-R.BT656 protocol packet or not?
Many thanks,
