NTE7084
Integrated Circuit
Color TV Sync Deflection Circuit
Description:
The NTE7084 is an IC containing not only the main functions required to achieve synchronization and
deflection in color television receivers but also a generator of horizontal, vertical blanking pulses, and
a generator of burst gate pulses (sandcastle type) in an 18–Lead DIP type package. This is a multi-
functional device ideally suited for use in color television receivers aiming at high–quality picture re-
production.
Functions:
D Synchronizing Separation
D Vertical Oscillation
D Vertical Drive
D Horizontal AFC
D X–Ray Protection
D Horizontal Oscillation
D Sandcastle Pulse (Burst Gate Pulse + Horizontal Blanking Pulse)
D Composite Blanking Pulse (Vertical + Horizontal Blanking Pulse)
Features:
D Horizontal and Vertical Oscillations are Stable Against Variations in Ambient Temperature and
Supply Voltage due to Small Warm–Up Drift.
D Small Variation in Horizontal Oscillation Frequency
D Good Linearity and Interlace because DC Bias at Vertical Output Stage is Subjected to Sampling
Control Within Retrace Time.
D Vertical Blanking Pulse Width can be set freely by Peripheral Parts.
D Minimized Picture Distortion because AFC Circuit is Defeated During Vertical Trigger Pulse Input
Period.
D Multifunctional and Compact
