Dear Sir/Madam
There is still a strong demand for high-tech analogue functions
in electronic systems. This includes sensors, amplifiers,
drivers, and RF components. In this Newsletter you´ll find new
products, articles, and design ideas which cover the analogue
aspects of electronic systems. Enjoy it!

1600x1200 Pixel Image Sensor (AvagoTechnologies)
The 2-megapixel CMOS image sensor ADCC-4050 fits in low-profile
camera modules to record high-definition videos (800x600 pixels)
at 30 frames per second. The sensor's 3D pixel e-field shaping
makes each pixel ultra light sensitive. The image sensor
automatically adapts to a wide range of lighting conditions down
to 5 lux - from incandescent to fluorescent to sunlight - and
corrects overexposed or underexposed images.

3.3V
HD/SD Reclocker (National Semiconductor)
The LMH0046 is an SMPTE 292M/259M-compliant reclocker
that automatically detects and re-times the incoming data stream to
suppress accumulated jitter. Features include 0.6-unit-interval
minimum jitter tolerance, lock detect, manual rate select, LVPECL
serial inputs and outputs, auto/manual bypass, and an output mute
function for data and clock.

210
and 50MHz Op Amps (Fairchild)
The 210MHz FHP3x50 and the 50MHz FHP3x30 families of
operational amplifiers allow designers to target a broad range of HD
and standard-definition (SD) video applications. Those include
set-top boxes, digital TVs and audio amplifiers.

Analogue-Signal
Processing (Phoenix Contact)
The line of mini-analogue-signal converters and
isolators can now be employed in explosive areas. The devices
fulfill the requirements for type «n" explosion protection and are
suitable for installation in Ex-Zone 2.

Trends in oscillator design
If the brain of an electronic system is the processor, then its
heartbeat is the frequency-control device that provides the
system clock. Both are vital components of the functional whole.
It should come as little surprise then that the market forces at
work upon the frequency-control sector are basically the same as
those that are shaping the electronics industry as a whole:
constant pressure to deliver higher performance, higher
functionality, smaller package size, lower power consumption,
lower pricing and faster turnaround of new designs. You can read
more about the Trends in oscillator design in the article by
Peter Sinclair
from C-MAC in EPN.

Viewpoint on the Analogue Market
There's a common misconception that all analogue
companies make high margins. This perception has primarily been
driven by a few firms that undeniably do make good gross margins -
with Intersil, Linear Technology and Maxim among this group. But
there are also lots of companies involved in the analogue space who
generate lower margins - examples being Sipex, On Semiconductor and
Fairchild Semiconductor. Additionally, there are companies that make
good margins through generating primarily digital products - such as
Microchip and Intel. Simon Prutton from
Intersil explains in his article in EPN what makes some
companies «high margin" and others «lower margin".

Hartley oscillator requires no coupled inductors
Examine a traditional Hartley-oscillator circuit, and you'll
note its trademark: a tapped inductor that determines the
frequency of oscillation and provides oscillation-sustaining
feedback. Although you can easily calculate the total inductance
for a given frequency, finding the coupling coefficient, k, may
require experimental, or "cut-and-try," optimization. This EDN
Design Idea by
Jim McLucas
presents an alternative
equivalent circuit that allows you to model the circuit before
building the prototype.

Line-powered driver lights up high-power LEDs
Using
LEDs has gained popularity as a method of saving power for
general-purpose lighting, but an efficient method for driving them
has also become a necessity. Providing power to a few LEDs may
require only a current-limiting resistor, but illumination
applications need a string of 20 or more LEDs to provide light over
an area. Based on On Semiconductor´s NCP1200A, a 100-kHz PWM
current-mode controller for universal offline power supplies, the
circuit in this EDN Design Idea by
Aaron Lager from
Masterwork Electronics
provides a low-cost, offline constant-current source for powering
multiple LEDs.

Business PC Users Admit to Storing Multimedia for Personal Use
Personal multimedia content holds a place within the US business
user’s work computer, even among senior-level staff, according
to In-Stat’s Business User Computing Survey. The survey was
aimed at determining what computer form factors and
configurations businesspeople are using, in order to draw
conclusions about how computers are being employed in relation
to media content.

Self on Audio,
Second Edition, by Douglas Self
Whether you are a dedicated audiophile
who wants to gain a more complete understanding of the design
issues behind a truly great amp, or a professional electronic
designer seeking to learn more about the art of amplifier
design, there can be no better place to start than with the 35
classic magazine articles collected together in this book.
Douglas Self offers a tried and tested method for designing
audio amplifiers in a way that improves performance at every
point in the circuit where distortion can creep in – without
significantly increasing cost.
