NTE1664
Integrated Circuit
TV Hotizontal/Vertical Sync Signal Processor
Description:
The NTE1664 is a silicon monolithic integrated circuit in a 22–Lead DIP type package designed for
use as a horizontal deflection circuit and vertical deflection circuit for color TV sets. This device contains two synchronization signal separators, a vertical oscillator, vertical sawtooth shaper, vertical
pre–driver, vertical retrace blanking pulse generator, horizontal AFC, horizontal oscillator, horizontal
pre–driver, and an abnormal high voltage prevention circuit.
Features:
D Two Synchronous Signal Separators for Very Stable Synchronization (Horizontal and Vertical
Signals are Independent of Each Other)
D Remarkably Improved Interlace Tracking due to Separate Wiring of Horizontal and Vertical
Sections
D Wide Range of Vertical Retrace Blanking Time due to Adjust Pin
D Very Low Oscillation Frequency Drift of Vertical and Horizontal Oscillator Against Ambient
Temperature
Absolute Maximum Ratings: (TA = +25°C ±3°C unless otherwise specified)
