TDA6800 Datasheet (NXP) - Video modulator circuit

TDA6800, Video modulator circuit

TDA6800 TDA6800T The TDA6800 is a modulator circuit for modulation of video signals on a VHF/UHF carrier.

The circuit requires a 5 V power supply and few external components for the negative modulation mode.

For positive modulation an external clamp circuit is required.

This circuit can be used as
