DESCRIPTION
The CNS7108 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.

Common Noise Applications
CNS7108 TYPICAL DATA
1. Built-in IF Testing:
Highly stable flat over frequency noise
sources serve to provide built-in test
for an IF subsystem. By injecting a
stable signal reference through the IF
chain, one can calibrate the gain/loss
and frequency response. In addition,
the noise source can be used to set
up Eb/No for built-in stimulated BER
testing of digital demodulation.
1. Barrage Jamming:
The noise source is fed into the tuning
port of a VCO via a bias tee and a posi-
tive 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 sig-
nal. Further circuitry can be used
between the noise source and tuning
port to shape the noise probability den-
sity function (PDF) for the desired jam-
ming effect.
2. Random Number Generation for
Encryption:
SPECIFICATIONS
Noise sources being truly random (not
pseudorandom) give the ultimate in
secure communication because of their
ability to generate a truly random num-
ber 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 sim-
pler 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 afterwards
using DSP.
