Video Amps And Modules FAQ
How does the internal clamp function work?
The sync-tip clamp circuit charges an external input capacitor during the sync tip of the video signal, fixing the minimum potential to a constant level (approximately 1.9V) and discharging it during other periods.
What is the purpose of the sag correction terminal?
The sag correction terminal allows connection of an external capacitor to correct low-frequency attenuation caused by output coupling capacitors, preventing vertical period sag without requiring excessively large output capacitors.
