DS90UB953-Q1: About DS90UB953Q1 colorbar Configuration.

Part Number: DS90UB953-Q1

HI,

Can you provide the color bar configuration of DS90UB953Q1 1080P@30fps and 1080P@60fps for our experiment?

Or how to setting?

In addition: about coaxial transmission, the requirements for the whole transmission wire?

thanks.

    Hello Yisyuan,

    You can find details on the PATGEN operation in the 953 datasheet section 7.6 along with a code example for 1080p @ 30fps. To increase to 60fps, half the line period field.

    For the transmission line, please reference the deserializer datasheet . For example, when paired with the 960 or 954 deserializer you can find the channel requirements in section 7.4.7.2 in the 960 datasheet.

    Best Regards,
    Casey

    Hello Casey，

    I'd  like to  confirm how to change the line  period to increase to 60fs? The line period register is 0X0C and 0X0D , how to configure it?  

    Best regards

    Kailyn

    Kailyn,

    See the datasheet for detailed descriptions of the 0x0C and 0x0D registers. You use them to program a 16 bit line period number in hex. The unit is 10ns, so for 60fps:

    PGEN_LINE_PD = ROUND(1/(TotalLines*60*10e-9))

    Take that number, convert it to hex and then enter it in the 0x0C/0x0D registers. The default value is for 1080p at 30fps, so you can also divide it by two for 60 fps.

    For YUV, you need to adjust the PGEN_CSI_DI register bits [5:0] based on what specific YUV format you are using and then adjust your total horizontal line size accordingly (based on the number of bytes per pixel for the YUV format you are using).

    Best Regards,
    Casey
