Overview
The LA7850 is a sync deflection circuit IC dedicated to CRT display use. It can be connected to the LA7832, 7833, 7837, 7838 (for vertical output use) to form a sync deflection circuit that meets every requirement for CRT display use.

Features
• The horizontal oscillation frequency can be adjusted stably from 15kHz to 100kHz.
• 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.
• Good vertical linearity because DC bias at vertical output stage is subject to sampling control within retrace time.

On-Chip Functions
