Monolithic Linear IC
LA7852
CRT Display Synchronization Deflection Circuit
Overview
The LA7852 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.
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 LA7852 contains these
peripherals on chip and adopts a stable circuit for horizontal
oscillation from 15 kHz to 100 kHz aiming at improving the
characteristics required for CRT display use.
The LA7852 has independent GND pins for the horizontal
block and vertical block, thus facilitating pattern layout for
applications where the LA7852 is used at high frequencies.

Features
. The vertical pull-in range is approximately 10 Hz at
. fv = 60 Hz.
The horizontal oscillation frequency can be adjusted stably
from 15 kHz to 100 kHz.
. 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 subjected 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.
