The TDA3566A is a decoder for the PAL and/or NTSC color television standards. It combines all functions required for the identification and demodulation of PAL/NTSC signals. Furthermore, it contains a luminance amplifier, an RGB matrix, and an amplifier. These amplifiers supply output signals up to 4 V peak-to-peak (picture information) enabling direct drive of the discrete output stages. The circuit also contains separate inputs for data insertion, analog and digital, which can be used for text display systems.
