clock frequency, which is determined by the panel timing requirements. The output of
LVDS is running at a fixed multiple of the dot clock frequency, which is determined by
the mode of operation; single- or dual-channel.
Depending on configuration and mode, a single channel can take 18 bits of RGB pixel
data plus 3 bits of timing control (HSYNC/VSYNC/DE) and output them on three
differential data pair outputs. A dual-channel interface converts 36 bits of color
information plus the 3 bits of timing control and outputs it on six sets of differential
data outputs.
This display port is normally used in conjunction with the pipe functions of panel scaling
and 6-to 8-bit dither. This display port is also used in conjunction with the panel power
sequencing and additional associated functions.
When enabled, the LVDS constant current drivers consume significant power. Individual
pairs or sets of pairs can be selected to be powered down when not being used. When
disabled, individual or sets of pairs will enter a low power state. When the port is
disabled all pairs enters a low power mode. The panel power sequencing can be set to
override the selected power state of the drivers during power sequencing.
