NTE1813 Integrated Circuit Color Signal Processor for VCR Description: The NTE1813 is an integrated circuit in a 22-Lead DIP type package. When combined with the NTE1814, this device provides the functions which process VCR color signals at the 2H/4H/6H mode is NTSC systems. Features: D Low Operating Supply Voltage: VCC = 5V D Low Power Consumption: 110mW D AFC and APC System in Recording Mode. APC System Only During Playback Mode. D Better S/N Ratio by Chroma ACC (2H/6H Mode).
