C7030-PBR-01B SmartSCAN™ CRT Controller

DESCRIPTION

SmartSCAN™ is an innovative, patented technique
developed by Genesis Microchip that enables conversion
of input line rates to either a fixed or controlled output
range. The gm7030 is the first device in the world to
integrate this function for use in CRTs. Using the
gm7030, CRT monitors are able to offer complete, multi­frequency compliance while taking advantage of the cost
and image benefits offered by a fixed line rate chassis.

By adjusting the input line rate, the gm7030 also creates
an Enhanced Vertical Resolution. This completely
eliminates the visible scan line structure of low-resolution
modes and increases the screen brightness.

Advanced digital RealColor™ processing enables the
gm7030 to offer visually stunning results by transforming
pictures into bright vibrant life-like images. CRTs
utilizing the gm7030 demonstrate clear visible
enhancements over all existing solutions.

With compatibility in mind, the gm7030 offers support
for both analog and digital input formats. A 5 Giga-Hz
(UXGA, 165 Mpps) Ultra-reliable DVI™ receiver with
incorporated HDCP 1.0 ensures compatibility with all
DVI 1.0 compliant sources. The 165MHz Analog to
Digital Converter accepts analog RGB.

A host of other features such as an OSD controller, sync
drop out protection, clock generator, internal test pattern
generator have been integrated into the gm7030. These
make the gm7030 an extremely low-cost, highly
integrated and easy-to-use solution for visually superior
fixed frequency or controlled line rate CRTs capable of
supporting multi-frequency inputs.
