Low-power LSI techniques for next-generation FTTH system

Demand for reduced power consumption of network devices is growing as Internet protocol traffic increases and fiber-to-the-home service penetration expands. This article describes our low-power-consumption technology developed for application to medium access control large-scale integrated circuits (LSIs) and analog front-end integrated circuits. Power saving is achieved with dynamic control according to the traffic state or link state, which reduces power consumption in LSIs and in entire network systems.
