NTE7063
Integrated Circuit
CRT Display Synchronization Deflection Circuit
Description:
The NTE7063 is a syncdeflection circuit IC dedicated to CRT display use. It can be connected to
the NTE1773, NTE1797, or the NTE1855 (for vertical output use) to form a syncdeflection circuit that
meets every requirement for CRT use.
So far, ICs for color TV use have been applied to the syncdeflection circuit for CRT display use and
general purpose ICs such as oneshot multivibrators, inverters, and a lot of transistors have been
used to form the peripherals such as sync input interface, horizontal phase shifter. The NTE7063 con-
tains these peripherals on chip and adopts a stable circuit for horizontal oscillation from 15kHz to
100kHz aiming at improving the characteristics required for CRT display use.
The NTE7063 has independent GND pins for the horizontal block and vertical block, thus facilitating
pattern layout for applications where the NTE7063 is used at high frequencies.
Features:
D
The Vertical PullIn Range is Approximately 10Hz at f
V
= 60Hz.
D
The Horizontal Oscillation Frequency can be Adjusted Stably from 15kHz to 100kHz.
D
The Horizontal Display can be Shifted Right/Left.
D
The Horizontal/Vertical Sync Input can be Used Intact Regardless of the Difference in Pulse
Polarity and Pulse Width.
D
The AFC Feedback Sawtooth Wave can be Obtained by Simply Applying a Flyback Pulse to
the IC as a Trigger Pulse.
D
Any Duty of the Horizontal Pulse can be Set.
D
Good Vertical Linearity because DC Bias at Vertical Output Stage is Subjected to Sampling
Control Within Retrace Time.
D
Excellent Interlace and Vertical Jitter Characteristics on the HighDefinition Display Because
of Independent GND Pins for the Horizontal Block and Vertical Block.
