can IMX6Q support the standard ITU-R BT.656 format or time multiplexed output with 54/108/162MHz?

[翔李]

hi,

Now i has 6-ch cvbs signals which are prcocessed by a ADC(TW6869),then outputs 2 streams of ITU656,one is time multiplexed with 108MHZ(the 4 of  6 cvbs signals),another is time multiplexed with 54MHZ(the 2of 6 cvbs signals).So,can IMX6Q support the 2 streams by its CPI/CSI/MIPI?

If CSI or CPI can,please give me a IC with output port of  CSI or CPI.

thanks.

Hi 翔 李

yes, it can there are 2xIPU and

sensor (pixel) max. clock frequency 180MHz

HI,

thanks.

In fact,other device will connect the CSI  or cpi_mipi of IMX6Q,as well as 6-ch cvbs signal.

I like connect imx6q's nvcc_csi(CSI0_DAT4---CSI0_DAT19 ) with the 6-ch cvbs signal,which is processed by ADC outputs 2 streams of ITU656,one is time multiplexed with 108MHZ(the 4 of  6 cvbs signals),another is time multiplexed with 54MHZ(the 2of 6 cvbs signals).and the nvcc_mipi(csi_0-3_DM/DP) is already used by other device.

IPU CSI input sensor (pixel) max. clock frequency 180MHz

[翔李]

hi，

the max. clock frequency 180MHZ is not meaning "imx6q support the format of time multipexed output(the one itu656 stream includes 6-ch cvbs signal information) .

Some cpu like ti's DM6467 DM3730 can directly connect this multipexed stream,but others like MG3500 can't do unless add a FPGA.

I want to know can the IMX6Q directly connect the multipexed-format stream without adding a FPGA.

Can you read and xrite in Chinese?

我的意思是，

我现在使用IMX6Q设计一款车载产品，我的需求是

1：6路模拟视频输入或者4路百万像素LVDS高清输入。

2：1路800万像素高清LVDS输入。

我现在想使用CSI接口连接800万像素相机，而CPI即MIPI的并口连接6路模拟或者4路LVDS高清（LVDS经过FPGA处理在给IMX6Q）。我想知道，我的6路CVBS模拟信号，经过前端的TW2864等ADC后，输出的一路6合1的复合视频数字流或者1路4合1 1路2合1数字流给IMX6Q的并行MIPI接口，IMX6Q能直接处理这种复合的数字流格式么（一个8bit的ITU656包括有4路或者6路的CVBS信息），我知道TI的DM6467 DM3730等芯片是能直接处理的，但IMX6Q能么？我不想使用模拟的ADC+FPGA方式。

如果CSI接口能的话，请推荐一款前端将模拟视频CVBS转为CSI接口的ADC，能匹配IMX6Q的视频输入接口的。

多谢。

you should parse 6ch stream in sw - fill buffer then separate data, so 180MHz is for

all 6 channels (180/6=30MHz per channel).

I do not read and write in Chinese. :smileyhappy:
