It extracts Csync from Cvid and also cleans up dirty sync signals.

It's a Sync Stripper. It's useful if you have an RGB monitor that requires clean synch.

In a lot of cases old game consoles output the sync information for RGB via composite video. If you're using an NEC XM family monitor for example, it won't be able to pull the synch information. This chip filters out the composite video signal so that the sync information is separated.
