5.7 SYNC1-3 INPUT CONTROL

As shown in Figure 11, the ADV7850 has three input synchronization control pins: SYNC1, SYNC2 and SYNC3. These pins are used for
signals with embedded synchronization, for example, SOG or SOY type signals. SOG is associated with RGB input video; SOY is
associated with component YPrPb input video. These synchronization inputs can be muxed to two synchronization strippers also in the
AFE. From here, the signals are routed to synchronization processors in the CP. This muxing can be performed in an automatic
configuration mode or with manual control. These are described in Sections
Rev. A May 2012
