INTEGRATED-CIRCUITS FOR DIGITAL TRANSMISSION-SYSTEMS

Integrated circuits will be a key element in the next generation of digital transmission systems. These systems must be fast, flexible, compact, cost effective, and highly reliable. Also, the power efficiency of these systems must be maximized to compensate for the increased power consumption and consequent increase in heat output that are associated with an increase in transmission speed. One of the most effective ways to achieve such a system is to use advanced integrated circuit technology. This paper looks at Fujitsu's latest integrated circuits for digital transmission systems, focusing on N-ISDN/B-ISDN transmission LSIs and gigabit optical regenerator ICs.
