, BIPOLAR ANALOG INTEGRATED CIRCUIT. FOR COLOR TV COLOR SIGNALS, VIDEO SIGNAL, AND SYNCHRONIZING SIGNAL OF PAL/NTSC SYSTEM a ‘The uPC1423 semiconductor integrated circuit processes color TV color signals, video signals, and synchronizing signals of the PAL/NTSC system. It enables color synchronization (APC), horizontal synchronization (H-HOLD), and vertical synchro- nization (V-HOLD) to be completely adjustment free, thus greatly reducing the number of peripheral parts and the number of adjustments. ‘The pPC1423 is contained in a 48 pin shrink DIP package suited to high-density mounting.
