PIN DESCRIPTIONS OF SHARED PINS BETWEEN
ANALOG AND DIGITAL INTERFACES
DATA OUTPUTS
RED—Data Output, Red Channel
HSOUT—Horizontal Sync Output
GREEN—Data Output, Green Channel
BLUE—Data Output, Blue Channel
A reconstructed and phase-aligned version of the video Hsync.
The polarity of this output can be controlled via a serial bus bit.
In analog interface mode, the placement and duration are
variable. In digital interface mode, the placement and duration
are set by the graphics transmitter.
The main data outputs. Bit 7 is the MSB. These outputs are
shared between the two interfaces and behave in accordance
with the active interface. Refer to the Analog Interface and
Digital Interface sections.
VSOUT—Vertical Sync Output
DATACK—Data Output Clock
The separated Vsync from a composite signal or a direct pass-
through of the Vsync input. The polarity of this output can be
controlled via a serial bus bit. The placement and duration in all
modes is set by the graphics transmitter.
Just like the data outputs, the data clock output is shared
between the two interfaces. It behaves differently depending on
which interface is active. Refer to the DATACK—Data Output
Clock section to determine how this pin behaves. .
SERIAL PORT (2-WIRE)
SDA—Serial Port Data I/O
SCL—Serial Port Data Clock
A0—Serial Port Address Input
For a full description of the 2-wire serial register, refer to the
2-Wire Serial Control Register Detail section.
