CMX7011 FAQ

 Q. Can I connect the CMX7011 Digital Scrambler directly into a radio’s audio path?
A. Yes, that is the intended use of the CMX7011, however there are a number of considerations that need to be taken into account. To achieve optimum performance, radio specific interface circuitry may be required.

When the radio is in digital voice scrambler mode the radio’s audio path: ‘pre/de-emphasis’, ‘companding’, ‘VOX’ and any audio band filtering, should be turned off or compensated for with suitable filtering.

Group delay is another potential problem area that is radio dependant and may require compensation.

Q. How much memory do I need to reserve in my host Flash memory to store the CMX7011 Function Image™.

A.  Realistically we do not expect the CMX7011 Function Image™ to exceed 48kbytes however, the absolute maximum size is 64kbytes.
