Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft’s control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO products described or contained herein.

Overview

The LA7860, 7860M display deflection integrated circuit supports multisynch and high-definition displays. Implemented through proprietary Sanyo circuit technology, it offers unsurpassed low-noise performance.

Its outstanding characteristic is the simplified processing it offers for screen settling in response to fluctuations in horizontal scan frequency, which has required numerous components and complex control procedures in the past. This has been made possible through a combination of the conventional phase shift function (H. SHIFT) with a new horizontal oscillation frequency dependent phase shift function (S. GAIN) implemented internally in the IC.

Control pins for various other internal functions support control at 0 to 2.5V dc, making it possible to simply control horizontal oscillation frequency and horizontal and vertical image phase directly with a microcomputer. When used in conjunction with an interface such as a DAC, it will also support system bus applications.
