Product specification
PAL/NTSC decoder
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. QUICK REFERENCE DATA All voltages referenced to ground. SYMBOL Supply VP IP V8(p-p) CON supply voltage (pin 1) supply current (pin 1) - - - - 12 90 PARAMETER MIN. TYP. 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.
TDA3566A
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.
