Dear Sir

we confuse DS90C385A mapping question, from DS90C385A datasheet figure 3 mapping is different snla014 application note shows.

May you pls suggest us which one is correct?

For example,from DS TxIN0 is R0;  snla014 Txin27 is R0.

                                                                       Best regards,

    Hi Bogey,

    There are two industry standard color mappings for 24-bit RGB. The options can best be described as placing the least significant bits (LSB) on LVDS channel 3 or placing the most significant bits  (MSB) on LVDS channel 3.

    The DS90C385A is able to handle any LVDS mapping, since the device only performs a simple serialization on the incoming data. However, you should be sure to select an LVDS mapping scheme that is compatible with your entire system including the selected deserilizer, gpu or display.
