VFS-3901H-1
HDTV Video Frame Synchronizer/Proc Amp
The VFS-3901H-1 video frame synchronizer is optimally designed to handle the ingest and timing
of HDTV video into a digital facility. It supports either composite black or tri-level reference
inputs. A video proc amp is included to correct input levels.
The VFS-3901 generates an audio video timing pulse on the NEO® midplane to permit separate
audio synchronizer modules to track the video synchronizer. This combination allows both audio
and video to be timed together into a digital facility.
All modules in the NEO family can be controlled locally by means of an intuitive card-edge
interface or remotely, using the Nucleus network control panel or CCS NAVIGATOR™.
