EXTERNAL HORIZONTAL AND VERTICAL SYNCHRONIZATION CONTROL
For timing synchronization purposes, the ADV739x is able to accept either EAV/SAV time codes embedded in the input pixel data or
external synchronization signals provided on the HSYNC and VSYNC pins (see Table 48). It is also possible to output synchronization
signals on the HSYNC and VSYNC pins (see Table 49 to Table 51).
