Monolithic Linear IC
LA7860, 7860M
Deflection IC Supports Multisynch Display
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.
Features
• Supports multisynch displays

Functions
• Horizontal frequency independent screen phase shift (H.
SHIFT)
• Horizontal frequency dependent screen phase shift
(S. GAIN)
• Vertical screen phase shift (V. SHIFT)
• Horizontal oscillation frequency control (H. OSC)
• Horizontal synchronization and detection (H. LOCK)
• Vertical blanking output (V. BLK)
