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鈥揕ead DIP type package. This is a multi-
functional device ideally suited for use in color television receivers aiming at high鈥搎uality picture re-
production.
Functions:
D
Synchronizing Separation
D
Vertical Oscillation
D
Vertical Drive
D
Horizontal AFC
D
X鈥揜ay 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鈥揢p 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
