TOSHIBA TOSHIBA Bi-CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC TB1231CN TB1231CN PAL/ NTSC 1CHIP (IF+ VCD PROCESSOR) IC TB1231CN is the IF & Video processing IC for PAL/NTSC color TV system. This IC demodulates PAL/ NTSC PIF, SIF and composite video signal to RIG I B primary colors and Audio signals. This IC can constitute Multi-Color System by combined with TA1275AZ (SECAM Processor). TB1231CN has the analog RIGIB interface, therefore it is easy to make up PIP system by using this IC. Because of the built-in video and audio switch, TB1231CN can deal with an external channel without extra switch. TB1231CN has an 12C BUS interface. Various controls (Brightness, Color etc.) can be done via two bus lines. SDIPSG-P-600-1.78 Weight 5.55g (Typ.
