Next generation DSL: single-chip ADSL+ and LDSL for home networks

In spite of the current downturn in the telecommunications sector, DSL has become arguably the most promising broadband delivery mechanism in the world. It is fueling an explosion of consumer electronics applications worldwide that demand a high rate of data transfer. By far the most popular form of consumer DSL is ADSL (asymmetric digital subscriber lines). ADSL can be realized with highly integrated silicon implementations. In this paper, we describe a single-chip ADSL customer premises modem/router that is capable of delivering 18+ Mbit/s of data to the home network.
