NTE1551 Integrated Circuit TV Video IF Amp Features: D High density one chip integration of vide IF amplifier, video detector, video preamplifier, AGC and AFC circuits. With this IC, compact set designing is possible. D High performance by built−in phase compensation type synchronous detector circuit. D As AFC using double balanced phase comparator, the influence to video detection is little. D Forward RF AGC and reverse RF AGC output pins are attached Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13.8V Circuit Voltage.
