LVDS to HDMI

pankajrana — Sat, 09 Aug 2014 11:45:20 GMT

Hello,

I would like to inquire on the possibility of LVDS to HDMI conversion. OK, I'll go into the details.

For one existing board - i.Mx6 Quad , supports one HDMI, but as per requirement, an additional HDMI monitor needs to be supported. For this we have thought of LVDS to HDMI conversion.

Current Approach:

LVDS Connector output	2nd HDMI connector i/p
LVDS_TX0 +/-	HDMI_D0 +/-
LVDS_TX1 +/-	HDMI_D0 +/-
LVDS_TX2 +/-	HDMI_D0 +/-

LVDS_clk +/-	HDMI_clk +/-

Remaining signals (I2C, etc) are taken care of , with similar settings as required for HDMI.

For the current approach we have planned for a customized wiring, and no usage of any converter. So any possible outcome of this experiment ??

Any feedback/reply will be highly appreciated.

Thanks.

Hi Pankaj

though electrically these interfaces may be connected,

lcd data/sync mapping is different and not transparent.

For example HDMI stream may embed audio data.

There are lvds-hdmi converters, for example below

CH7036

You have any adapter board supports LVDS to HDMI? Takes only LVDS Input signals and power.

Thanks
