NJM2527

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. s PACKAGE OUTLINE NJM2527FR2 s FEATURES q NTSC/PAL matching (Resemblance PAL de-modulation system) q Internal Y/C separate circuit q Input mode: Composite video signal, Y/C separate signal, External RGB signal www.DataSheet4U.com q Internal synchronous separate circuit (Liquid crystal panel PLL use) q Internal black level insertion circuit (Use for aspect ratio change) q Internal Gamma 2-point correction circuit q Bipolar technology q Package Outline QFP48-R2 s BLOCK DIAGRAM SIDEBLACK SUBVG2B SUBVG2R SUBVG1B SUBVG1R BRIGHT ROUT RDET EXTINR VCC2 s PIN CONFIGURATION 1 .
