TOSHIBA TB1238N TOSHIBA Bi-CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC TB1238N PAL/NTSC 1CHIP (IF + VCD PROCESSOR) IC TB1238N is the IF & Video processing IC for PAL/NTSC color TV system. This IC demodulates PAL/NTSC PIF, SIF and composite video signal to R/G/B primary colors and Audio signals. This IC can constitute Multi-Color System by combined with TA1275AZ (SECAM Processor). TB1238N has the analog R/G/B interface, therefore it is easy to make up PIP system by using this IC. Because of the built-in video and audio switch, TB1238N can deal with an external channel without extra switch. TB1238N has an [C BUS interface. Various controls (Brightness, Color etc.) can be done via two bus lines.
