Video Circuit Collection &mdash AN57
PDF, 559 Kb, File published: Jan 2, 1994
AN57, the Video Circuit Collection, features a variety of video circuits designed at LTC. The LT1204 70MHz multiplexer is featured in a number of circuits which require excellent video isolation from channel to channel. High speed voltage and current feedback amplifiers are highlighted throughout the section on video processing circuits. There is a section on applying Current Feedback Amplifiers (CFAs) and a number of articles taken from the Linear Technology magazine.

INTRODUCTION
Even in a time of rapidly advancing digital image processing, analog video signal processing still remains eminently
viable. The video A/D converters need a supply of properly
ampliп¬Ѓed, limited, DC restored, clamped, clipped, contoured, multiplexed, faded and п¬Ѓltered analog video before
they can accomplish anything. After the digital magic is
performed, there is usually more amplifying and п¬Ѓltering
to do as an adjunct to the D/A conversion process, not to mention all those pesky cables to drive. The analog way
is often the most expedient and efп¬Ѓcient, and you donвЂ™t
have to write all that code.
The foregoing is only partly in jest. The experienced engineer
will use whatever method will properly get the job done;
analog, digital or magic (more realistically, a combination
of all three). Presented here is a collection of analog video
circuits that have proven themselves useful. CIRCUIT INDEX

DESIGN FEATURES 250MHz RGB Video Multiplexer in
Space-Saving Package Drives
Cables, Switches Pixels at 100MHz
by John Wright and
Frank Cox Dense Process Yields
One of the first products from LTCвЂ™s Big Performance from
new proprietary high speed bipolar Tiny PC Board Space
Introduction process is a 250MHz RGB (red, green,
blue) multiplexer that is optimized for
switching speed and makes excellent
use of the new complementary 6GHz
transistors. This new MUX, the
LT1675, is designed for pixel switching in video graphics and for RGB
routing. It is configured with three
SPDT (single pole, double throw) RGB
video switches and three current feedback amplifiers for direct driving of
cables.
The new RGB MUX is similar to the
LT1203/LT1205 video switches combined with the LT1260 triple CFA, but
with greatly enhanced performance
in far less space. The boost over the
older configuration is a factor of five
in switching speed and a factor of 2.5 …
