Connecting to lvds input with i.MX6

beomseokoh — Tue, 15 Jul 2014 06:22:50 GMT

I want to connect lvds dual channel input (upto 1920x1080 60Hz) with i.MX6.

And I am going to use lvds to rgb converter chip (lvds to rgb 24bit [r8 + g8 + b8 + vsync + hsync +clk]).

Question

1. Which port do I connect rgb-24 signal on iMX6.

1. ipu-disp0-dat[0-23] : Is this port display only?

2. csi x : rgb565

3 Any other port do you know or recommend?

2. Do you have any other idea?

Please let me know How to interface lvds input.

Thank you in advance.

Hi beomseok

lvds can not be inputted to i.MX6 processor.

I.MX6 processor has only lvds output (LDB module).

Dear chipexpert

Thank you for your help

What i am asking is Which port do I connect rgb-24 signal on iMX6 not directly lvds input.

Hi beomseok

RGB can be inputted using CSI, please check

Table 66 "Camera Input Signal Cross Reference, Format, and Bits Per Cycle"

i.MX6DQ Datasheet (rev.3, 2/2014)

Dear chipexpert

Thank you for your help

According to Table 66.

There is RGB565 16bits 2 Cycle. (in Red rectangle)

Why is it 2 Cycle, Maybe miss-print?

I could be 1 cycle is correct.
