TDA8501 The TDA8501 is a highly integrated PAL/NTSC encoder IC which is designed for use in all applications where R, G and B or Y, U and V signals require transformation to PAL or NTSC values.The specification of the input signals are fully compatible with the specification of those of the TDA8505 SECAM-encoder. ORDERING INFORMATION EXTENDED TYPE NUMBER .
• Two input stages: R, G, B and −(R−Y), −(B−Y), Y with multiplexing
• Chrominance processing, highly integrated, includes low frequency filters for the colour difference signals, and after the modulator a bandpass filter
• Fully controlled modulator produces a signal according to the PAL or NTSC standard without adjustments
• A free running oscillator. Can be tuned by crystal or by an external frequency source
• Output stages with separated Y + SYNC and chrominance (Y + C, SVHS), and a CVBS output. Signal amplitudes are correct for 75 Ω driving via an external emitter follower. Internal genera.
