SIGNAL PROCESSOR FOR COLOR TFT
s GENERAL DESCRIPTION The NJW1300B is a color TFT signal processor which include color signal modulator , count down circuit , RGB demodulator , RGB interface , and common pole driver , required by color TFT signal processing after Y/C separator. It corresponds broadcasting systems of both NTSC and PAL , because it can select the down (1/525 or 1/625) by the internal switch. The NJW1300B is suitable for TFT LCD panel and car navigation systems. s FEATURES q Supply Voltage 5V q Y/C Separator Input q NTSC/PAL System (3.58MHz, 4.43MHz) q Unnecessary Adjustment of Oscillation Frequency for Internal Count Down Circuit. q External One System Input for Analog RGB q Internal Enhancer Circuit q Internal GAMMA 1 Point Correction Circuit q Internal Color TFT Common Pole Driver q Bi-CMOS Technology q Package Outline TQFP64 s BROCK DIAGRAM
