LA7852

Ordering number: EN2781B 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 syncdeflection 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.
