Video modulator circuit

TDA6800

TDA6800T

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.

Features

• Balanced modulator

• Symmetrical oscillator

• Video clamp circuit for negative modulation

• Frequency range 50 to 800 MHz
