NTE7086
Integrated Circuit
Sync Deflection Circuit for CRT Display
Description:
The NTE7086 is a syncdeflection circuit IC in a 20鈥揕ead DIP type package dedicated to CRT display
use. This device can be connected to the NTE1773/NTE1797 (for vertical output use) to form a
syncdeflection circuit that meets every requirement for CRT display use.
So far, IC鈥檚 for color TV use have been applied to the syncdeflection circuit for CRT display use and
general鈥損urpose IC鈥檚 such as one鈥搒hot multivibrators, inverters, and a lot of transistors have been
used to form the peripherals such as the sync input interface and horizontal phase shifter.
The NTE7086 contains 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.
Features:
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 Linearity because DC Bias at Vertical Output Stage is Subjected to Sampling Control
within Retrace Time.
