Automatic Synchronization Configuration; Manual Synchronization Configuration - Analog Devices Advantiv ADV7604 Hardware Manual

6.4.1 Automatic Synchronization Configuration

In addition to configuring the analog input muxes, AIN_SEL[2:0] automatically controls the
associated synchronization channel routing for signals with embedded synchronization, for
example, Sync on Green (SOG) or Sync On Y (SOY) type signals.
SOG is associated with RGB input video; SOY is associated with component YPrPb input video.
Table 8 shows the routing details when AIN_SEL[2:0] is programmed.

6.4.2 Manual Synchronization Configuration

Figure 12 shows the two input synchronization muxes, which can be controlled manually as well as
automatically. This section describes the control bits for manual operation.
