Abstract: The tetecommunications market places an unusual challenge on the semiconductor design engineer. The greatest potential for the high volume use of integrated circuits lies at the periphery of the equipment where it interfaces with the user. Yet this is just where the most hostile electrical environment is to be found. Accordingly, the use of modern microelectronics started at the heart of the system, where the environment was well regulated. Initially this included only the control functions; later, digital sw…
