Part Number: DS90UB960-Q1

hi team,

Customer use 4*933+960 and meet the green layer issue, after changing 0x7c from 0x80 to 0x0C, they get right output.

Confirm 933 is in RAW10 mode and input data is YUV422.

Can you explain why Raw10 8-bit mode makes this difference? It's not clear described in datasheet.

Regards,

Hello Dongbao,

How many bits (parallel inputs) are you using on the 933? 8-bits or 10-bits?

It's 8 bits, from D0 to D7, rest of pins are floating. --this is what i see from the datasheet.

It's aligned with camera module spec, YUV422 data format and 960:0x70=0x1E Raw10 YUV422

Let me check with customer whether they change 0x70 from 0x80 to 0xC0 instead of 0x0C.

Hello Dongbao,

If they are using just 8-bits on the SER, then the DES register 0x7C[7:6] must be either 10 or 11. It can't be 00.
Also, they have changed bit[2] auto detect. This may have some impact!

hi Hamzeh,

Confirm change 0x70 from 0x80 to 0xC0 solve the issue, 0x70 setting should align with 933 DVP input (D0-D7), thanks
