Features

(3.2)
The LC74982W is an LCD display scan converter IC that
converts NTSC and PAL TV signals to XGA resolution.
The video signal-processing circuits required to implement
an LCD TV set can be easily formed by combining this IC
with a digital decoder, a microcontroller, and an LCD
panel. Since this IC does not require an external frame
memory for resolution conversion, it can contribute to
minimizing total costs. As additional functionality, it also
provides inputs for personal computer video (up to XGA)
and digital TV (480p/480i). Since LC74982W operation is
based on expansion (resolution increasing) processing,
depending on the input resolution, it can also support use
of, for example, 800 × 600 and 800 × 480 dot resolution
LCD panels. Thus the LC74982W can be used in a wide
range of applications.
• Built-in γ correction (LUT technique. Each 8-bit R, G,
and B signal is independently programmable.)
• Built-in OSD function (8 colors, 253 characters)
• I2C bus interface
• Constant frame-rate processing (identical frame periods
in the input and output signals) adopted so that no
external memory is required.

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.
In the event that any or all SANYO products (including technical data, services) described or contained
herein are controlled under any of applicable local export control laws and regulations, such products must
not be exported without obtaining the export license from the authorities concerned in accordance with the
above law.
