descriPtion  
The Extron VSS 100 Video Sync Separator is for systems that use video formats with embedded  
sync, in particular with the SCART connector found in Europe. Sources such as DVD players with  
RGB and composite video output on a SCART connector can now be used with RGB switchers  
like the Extron System 7SC. Simply use the RGB output of the DVD player and composite sync  
output from the VSS 100. The VSS 100 also extracts the sync signal from RGsB, component  
video, S-video, or composite video inputs. It then outputs the composite sync signal, at TTL  
levels, on a separate signal line. The original video signal is looped through unchanged.

S-video), or composite video  
Output type....................... 1 loop-through Gs (green and sync from RGsB), Y (luma signal from component  
video or S-video), or composite video  
1 composite sync output on 1 BNC female connector

Output impedance .............. 75 ohms  
Max. propagation delay........ 50 ns  
Max. rise / Fall time............. 2.5 ns  
Polarity ............................ Negative  
Systems can take advantage of Extron technologies that depend on a separate sync input such  
as the DSVP- Digital Sync Validation Processing feature on the Extron CrossPoint 450 Plus  
matrix switchers. Exclusive to Extron, DSVP confirms that input sources are active by scanning  
all sync inputs for active signals. DSVP provides instantaneous frequency feedback for  
composite sync or separate horizontal and vertical sync signals via the switcher's RS-232 and  
RS-422 or Ethernet port.

The VSS 100 fits behind a rack-mounted Extron switcher. For easy integration into the system,  
it includes a 6 inch male-to-male BNC cable. The sync separator has an external, international  
power supply that can drive up to four VSS 100s.
