Video Amps And Modules FAQ

How does the internal clamp function operate?

The sync-tip clamp circuit charges an external input capacitor during the video signal sync tip to fix the minimum potential at a constant level (approximately 1.9V), discharging it during other periods.

What is the purpose of the SAG terminal?

The SAG terminal allows connection of an external capacitor to correct low-frequency attenuation caused by output coupling capacitors, preventing vertical sag in the video signal without requiring excessively large output capacitors.
