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
• DC control
• Low noise
• Supports polar input signals
• TTL output
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)

Specifications of any and all SANYO products described or contained herein stipulate the performance,
characteristics, and functions of the described products in the independent state, and are not guarantees
of the performance, characteristics, and functions of the described products as mounted in the customer’s
products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,
the customer should always evaluate and test devices mounted in the customer’s products or equipment.
SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.
