I know that ADV7611 convert HDMI to VGA & audio..
but i want to know how can converting HDMI to LVDS for display LCD resolution 800 X480??
The question is really what is the LVDS standard your panel is supporting.
LVDS is only a signalling method; a different one than TTL. If you are from
networking background - you may consider LVDS as a physical low-level
layer, above which there is yet another "encapsulated" layer - e.g. openLDI.
OpenLDI constains serialized data.
The ADN4663 is in fairness a TTL to LVDS converter but not a serializer.
