7106
200 KHZ TO 12 MHZ
DESCRIPTION
The SMN7106 noise module is designed
for a wide range of applications.
It features high noise output amplitude
for uses ranging from encryption to jam-
ming. All biasing and amplification circuit-
ry is built-in making it easy to design into
your system. It features a built-in voltage
regulator for highly stable output even if
your DC supply lines are not.

PRODUCTS:
The SMN7106 noise sources being sur-
face mount, having a small footprint and
available on tape and reel, make them
ideal for production manufacturing.
Traditionally packaged noise sources
have been large and costly rendering
them less suitable for all but the more
expensive, exotic systems. Noise can
now be thought of as lower cost, more
reliable, smaller and easier to implement
alternative to costly microprocessor
based solutions such as PN generators,
arbitrary waveform generators and DSP
processors.
APPLICATION NOTE
Common Noise Applications
1. Barrage Jamming: The noise source is fed into the tuning port of a VCO via a
bias tee and a positive DC voltage. The random nature of noise makes the output of
the VCO to hop around in a given frequency band randomly making an ideal jamming
signal. Further circuitry can be used between the noise source and tuning port to
shape the noise probability density function (PDF) for the desired jamming effect.
2. Random Number Generation for Encryption: Noise sources being truly random
(not pseudorandom) give the ultimate in secure communication because of their ability
to generate a truly random number pattern. This can be used to seed an encryption
key for authentication. The noise signal can be fed directly into an A/D converter for
sampling or a simpler techniques might use a comparator. Further shaping of the
noise is often employed whether either analog if in front of the A/D converter or after-
wards using DSP.
