NTE1483 Integrated Circuit Video IF System
Description: The NTE1483 is a silicon monolithic integrated circuit in a 22-Lead DIP type package designed for use in the PIF section in color TV receivers. As it contains a separate picture detector and sound IF detector, this device offers low buzz characteristics. The NTE1483 has all functions including picture IF amplifier (4th), picture low-level detector, sound IF detector, AFC detector, IF AGC, RF AGC and picture amplifier. Features: D Low Buzz Characteristics for Audio Multiplex TV D High Input Sensitivity D Wide AGC Control Range D Contains Differential Mode Input for use with SAW Filter Absolute Maximum Ratings: (TA = +25C unless otherwise specified) Supply Voltage (Pin13), V13max . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15V Pin22 Current, I22max . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100mA Pin14 Current, I14max . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3mA Power Dissipation (TA +65C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 900mW Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -15 to +65C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 to +125C Electrical Characteristics: (TA = +25C, VCC = 12V, RA = 120, fp = 58.75MHz unless otherwise specified)
