7751SRG-HD
HD-SDI Tri-Level Sync Generator
The 7751SRG-HD generates various analog bi-level & tri-level sync signals for both HD and SD applications. The 7751SRG-HD provides an analog genlock input that allows you to synchronize the sync signals to your plant horizontal and vertical timing.
The 7751SRG-HD generates all analog sync signals defined by SMPTE 274M (1080i/p) and SMPTE 296M (720p) as well as those required for NTSC, PAL and slow PAL (625i/48) applications. Sync signals generated for NTSC, PAL and slow PAL applications are sync signals only and do not incorporate color burst signals. 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.
In conjunction with the 7700ADA7 Analog Distribution Amplifier and the 7751TG2-HD HDTV Test Signal Generator, this module will fulfill all of your slave sync generation requirements. Should a failure occur, using the 7700ACO-HD or 500ACO2-HD/SD in conjunction with the 7751SRG-HD makes for a high availability of master reference throughout the plant.
