DS90UB960-Q1: Typical application in Automotive

Tool/software:

Hello

Please help to check the Deserializer is capable for the block diagram as below.

Or other suggestions.

Is it able to sync CSI 3 & CSI 4 ?

DES#1 : 4 side cams ( 3MP @ 30fps)

DES#2 : rear cam ( 3MP @ 30fps) + front cam ( 8MP @ 30fps)

DES#3: 4 surround cams ( 3MP @ 30fps)

Hello Ho,

can you provide the data type of all cams? for example, YUV422 10-bit , RAW12, RGB444 ...etc

Also, you said

What do you mean by able to sync CSI3 and CSI4? These are outputs, how do you think they should be synced?

Hi Hamzeh

1) Format of all 3MP cams is YUV422, 8-bit

2) 8MP cam is RAW 12-bit

2. 4 surround views are combined to 1 MIPI stream, then we want to output both CSI_3 & CSI_4 at the same time.

CSI 3 is the same as CSI 4, CSI 3 connect to SoC TDA4 for further processing, CSI 4 displays on screen directly through serializer

Hello Ho,

DES#1 : 4 side cams ( 3MP @ 30fps)

calculating the data rate from one cam = Hres x Vres x blanking x FR x #bits/pixle = 2048 x 1536 x 1.2 x 30 x 16 = 1.81Gbps

4x Cameras = 1.81Gbps x 4 = ~7.2Gbps which is higher that the UB964 can support on a single CSI Tx port.

This is not going to work using the UB960. You need to use the UB9702 instead.

calculating the data rate for the 8MP cam = Hres x Vres x blanking x FR x #bits/pixle = 3840 x 2160 x 1.2 x 30 x 12 = 3.584Gbps

The datarate is not supported by 1x RX input port of the UB960. You need to use the UB9702 instead.

Same as DES #1
