2 / 24 page February 1994 2 Philips Semiconductors Product specification PAL/NTSC decoder TDA3566A FEATURES • A black-current stabilizer which controls the black-currents of the three electron-guns to a level low enough to omit the black-level adjustment • Contrast control of inserted RGB signals • No black-level disturbance when non-synchronized external RGB signals are available on the inputs • NTSC capability with hue control. APPLICATIONS • Teletext/broadcast antiope • Channel number display. GENERAL DESCRIPTION The TDA3566A is a decoder for the PAL and/or NTSC colour 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 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. QUICK REFERENCE DATA All voltages referenced to ground.
