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.
