The 7750SRG-HD generates various analog bi-level and tri-level sync signals for both HD and SD applications.  The 7750SRG-HD provides an analog genlock input that allows you to synchronize the sync signals to your plant horizontal and vertical timing. The 7750SRG-HD generates all analog sync signals defined by SMPTE 274M (1080i/p) and 296M (720p) as well as those required for NTSC, PAL and slow PAL (625i/48) applications.  The four independent sync outputs can be configured to output different sync signals.  The common combinations of HDTV and SD analog sync outputs can be selected via card edge control.
