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.  
APPLICATIONS  
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.
