DS90CF384AQ-Q1: Reference circuit

Hi Ikram,

For RxOUT, how to map RxOUT and R0~R7,G0~G7,B0~B7?

Regards,

Roy

Hi Roy,

How the output RxOUT are connected to the RGB and HS/VS/DE pins depends on the incoming LVDS format.

There are two mapping formats for LVDS: VESA and JEIDA.
These formats are explained in this app note: https://www.ti.com/lit/an/snla014a/snla014a.pdf



Therefore, depending on the input LVDS format, the output will have to be connected accordingly.

For example,

• JEIDA format, RxOUT0 -> R2
• VESA format, RxOUT0 -> R0

Note that TxIN0 in this diagram would correspond to RxOUT0 on the DS90CF384AQ-Q1. Similarly the mapping for each RGB 0-8 can be found from this diagram based on the LVDS mapping from the source (serializer or LVDS video input from SoC).

Best regards,
Ikram
