LA7850
Overview
The LA7850 is a sync deflection circuit IC dedicated to CRT display use. It can be connected to the LA7832, 7833, (for
vertical output use) to form a sync deflection circuit that meets every requirement for CRT display use.
So far, ICs for color TV use have been applied to the sync deflection circuit for CRT display use and general-purpose ICs
such as one-shot multivibrator, inverter and a lot of transistors have been used to form the peripherals such as sync input
interface, horizontal phase shifter. The LA7850 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
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 fly back 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.
