INTEGRATED CIRCUITS DATA SHEET TDA3566 PAL/NTSC decoder Preliminary specification File under Integrated Circuits, IC02 May 1989 Philips Semiconductors Preliminary specification PAL/NTSC decoder GENERAL DESCRIPTION TDA3566 The TDA3566 is a monolithic integrated 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, analogue as well as digital, which can be used for text display systems (e.g. Teletext/broadcast antiope), channel number display, etc. 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 Supply voltage (pin 1) Supply current (pin 1) Luminance amplifier (pin 8) Input voltage (peak-to-peak value) Contrast control range Chrominance amplifier (pin 4) Input voltage range (peak-to-peak value) Saturation control range RGB matrix and amplifiers Output voltage at nominal luminance and contrast (peak-to-peak value) Data insertion Input signals (peak-to-peak value) Data blanking (pin 9) Input voltage for data insertion Sandcastle input (pin 7) Blanking input voltage Burst gating and clamping input voltage PACKAGE OUTLINE 28-lead DIL; plastic, with internal heat spreader (SOT117); SOT117-1, 1996 November 21.

Philips Semiconductors Preliminary specification PAL/NTSC decoder FUNCTIONAL DESCRIPTION TDA3566 The TDA3566 is a further development of the TDA3562A. It has the same pinning and almost the same application. The differences between the TDA3562A and the TDA3566 are as follows: · The NTSC-application has largely been simplified. In the case of NTSC the chroma signal is now internally coupled to the demodulators, ACC and phase detectors. The chroma output signal (pin 28) is suppressed in this case. It follows that the external switches and filters which are needed for the TDA3562A are not needed for the TDA3566. Furthermore there is no difference between the amplitude of the colour output signals in the PAL or NTSC mode. The PAL/NTSC-switch and the hue control of the TDA3566 and the TDA
