NJM2529
COLOR TFT SIGNAL PROCESSOR
s GENERAL DESCRIPTION
The NJM2529 is a color TFT signal processor.
It contains all function, like as Y/C separator circuit, color signal
de-modulator, synchronous separate circuit, RGB interface, side
black control circuit, and common pole driver, required by color TFT
signal processing.
The NJM2529 keeps selecting NTSC/PAL with external VCXO
circuit TRAP circuit for each broadcasting.
