Philips Semiconductors
Video modulator circuit

GENERAL DESCRIPTION

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 a general purpose modulator without additional external components.
