NTE1814

NTE1814 Integrated Circuit CMOS, Color Processing Circuit for VCR Description: The NTE1814 is a CMOS LSI integrated circuit in an 18–Lead DIP type package designed for use in VCR color signal processing circuits for VHS system video tape recorders. This device is used in configuration with the NTE1813 for color signal processing in 2, 4, and 6Hr modes in NTSC VCR systems. Features: D In Recording, a Video Color Signal can be Converted into a Low–Frequency Video Color Signal by AFC and REC APC. D In Playback, the Low–Frequency Color Signal can be Converted into the Original Video Color Signal on the Color Subcarrier Wave Frequency by PB APC and the Side Lock Detect Circuit. D The NTE1814 Contains the Following Functions: Rotary Circuit DPLL (Digital Phase Locked Loop) Circuit Side Lock Detect Circuit Field Start Inhibit Pulse Generating Circuit Burst Adjust Pulse Generating Circuit Burst Gate Pulse Generating Circuit Monostable Multivibrator Circuit Phase Comparator D Can be Miniaturized and Simplified with High Reliability D Low Power Dissipation: 15mW @ 5V Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Supply Voltage, VDD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.3 to +8.0V Input Voltage, VI . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.3V to VDD+0.3V Output Votage, VO . . . . . . . . . . . . . . . . . . . . . . . . . . . . ...
