NJM2527
COLOR TFT SIGNAL PROCESSOR
s GENERAL DESCRIPTION
The NJM2527 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, and
sideblack control circuit, required by color TFT signal processing.
The NJM2527 keeps selecting NTSC/PAL with external VCXO
circuit TRAP circuit for each broadcasting.
