Monolithic Linear IC
LA7853
CRT Display Synchronization
Deflection Circuit
Overview
The LA7853 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 deflec-
tion 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 LA7853
contains these peripherals on chip and adopts a stable cir-
cuit for horizontal oscillation from 15kHz to 100kHz aim-
ing at improving the characteristics requierd for CRT
dispaly use.
The LA7853 has independent GND pins for the horizontal
block and vertical block, thus facilitating pattern layout for
applications where the LA7853 is used at high frequen-
cies.

Features
• The vertical pull-in range is approximately 20Hz, 2 times
that of the LA7852, at fV=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 vertical linearity because DC bias at vertical output
stage is subject to sampling control within retrace time.
• Excellent interlace and vertical jitter characteristics on
the high-definition display because of independent GND
pins for the horizontal block and vertical block.
