12 Attachment: Technical Information
12.8.25 VSG - Video Sync Generator
The VSG is a video signal reference for Studio Equipment with four BNC outputs. The Module generates 1x
bi-level sync (Black Burst) and 1x Tri-Level Sync and 2x Sync Signals (H-Sync, V-Sync, .. .). The LANTIME
Web Interface can be used for output signal configuration and to query the state of the VSG.
Functionality
The board is synchronized by an external 10MHz signal. It generates configurable video signals in different
formats. The generated signals have a phase reference to 1PPS.
