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
