... SOT137-1; 1996 December 2. April 1993 GENERAL DESCRIPTION The TDA8501 is a highly integrated PAL/NTSC encoder IC which is designed for use in all applications where R, G and 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 ...

... Philips Semiconductors PAL/NTSC encoder FUNCTIONAL DESCRIPTION The TDA8501 device comprises: encoder circuit oscillator and filter control sync separator and pulse shaper. Within this functional description, the term Y is used to describe the luminance signal and the terms U and V respectively, are used to describe the colour difference signals ...

... If pin 4 is left open, the internally generated H/2 pulse (output) is connected to this pin. NTSC mode: alternation of the V modulation is not allowed. If pin 4 is not used for set-up control (see Y +SYNC, CVBS and Chrominance outputs), it can be left open-circuit or connected to ground. 7 Preliminary specification TDA8501 ...
