LA7858
Overview
The LA7858 is syncdeflection circuit IC dedicated to CRT display use. They can be connected to the LA7838 (for vertical
output use) to form a syncdeflection circuit that meets every requirement for CRT display use.
The LA7858 is performance-improved versions of the existing LA7853. The LA7858 is intended for use in very
high-definition display (fH = 64 to 150kHz) applications. When the horizontal frequency exceeds approximately 64kHz,
problems are experienced with horizontal jitter which has been less of a problem in low-frequency display applications.
The newly developed LA7858, which are fabricated with a special production process, are capable of suppressing
horizontal jitter components successfully (30% reduced as compared with our existing similar Type Nos.). The LA7858 is
ideally suited for use in high performance-required applications.
The LA7858 is pin-compatible with the LA7853, respectively. The LA7858 is different in the vertical sync pull-in range
(LA7858 : 20Hz).
Features
The horizontal oscillation frequency can be adjusted stably from 15kHz to 150kHz.
The horizontal display can be shifted right/left.
The horizontal/vertical sync input can be used intact regardless of the difference in pulse polarity and pulse width.
The AFC feedback sawtooth wave can be obtained by simply applying a flyback pulse to the IC as a trigger pulse.
Any duty of the horizontal pulse can be set.
The LA7858 can be connected to the LA7838 to develop pictures with the interlace characteristics, crossover distortion
characteristics improved.
