3.2.9 Carrier Based 24 bit Color Depth LVDS
The Module parallel LCD path may be used to implement single or dual channel Carrier Board LVDS transmitter(s).
The color packing may be 24 bit or 18 bit. Since 18 bit single channel color packing is already available from the
Module LVDS, only 24 bit color packing is described in this section.
A single channel implementation uses one SN75LVDS83B (or equivalent) LVDS transmitter and a dual channel
implementation uses one Thine THC63LVD827 (or equivalent) LVDS transmitter. The same dual channel LVDS
transmitter can be used for single channel LVDS implementation, if the feature is available on the transmitter.
The following table shows how the sA3874i LCD pins should be mapped to TI SN75LVDS83B, for standard single
channel LVDS 24 bit color packing. The chart shows pin numbers for the BGA version of the part. The TSSOP
version can be used as well, although the pin numbering is different. The pin names remain the same.
Transmitters from other vendors may be used as well.
