Monolithic Linear IC
LA7851
CRT Display Synchronization
Deflection Circuit
Overview
The LA7851 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 LA7851
contains these peripherals on chip, has a wide vertical pull-
in range of 20Hz, and adopts a stable circuit for horizontal
oscillation from 15kHz to 100kHz aiming at improving the
characteristics requierd for CRT display use.

Features
• The vertical pull-in range 20Hz permits non-adjusting at
vertical sync 50Hz/60Hz.
• The horizontal oscillation frequency can be adjusted sta-
bly from 15kHz to 100kHz.
• The horizontal display can be shifted right/left.
• The horizontal/vertical sync input can be used intact re-
gardless 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 linearity because DC bias at vertical output stage is
subject to sampling control within retrace time.
