SIMULATES THE EFFECT OF COAXIAL CABLE IN SERIAL DIGITAL SYSTEMS

In serial digital applications it is known that a signal adhering to the amplitude specification of 800mV + 10% will maintain its integrity if the attenuation at the Nyquist frequency is 30dB or less. It may then be reconstituted correctly by, say, the Sony deserialiser.

The Faraday CABLE CLONE has similar attenuation vs frequency characteristics to coax cable over the wide frequency spectrum of the serial digital signal. When installing or testing serial digital equipment it is often necessary to establish the maximum length of cable over which the signal will remain useable, or to ensure there is sufficient margin (headroom) if a certain length of cable is required. Most adaptive equalisers, in deserialisers for example, rely on the attenuation characteristics of the cable to operate correctly.

At present the only way to do this is to insert the actual length of cable into the path. This is time consuming, inconvenient and costly.

 The Faraday CABLE CLONE is the solution to the problem.
