Product Brief
The SOCRATES-4e/2e/1e are the first members of Infineon's 3rd
generation SOCRATES®-family of SHDSL transceivers designed for EFM-
(Ethernet First Mile) system applications.
Featuring single, dual or four channel variants, the SOCRATES-e
family of single-chip solutions is fully compliant with standards of ETSI
(SHDSL, SHDSL.bis), ITU (G.shdsl, G.shdls.bis, G.hs) and IEEE (EFM).
Advanced system functionality and outstanding performance as well as
optimized board-space and power-saving features provide market unique
advantages for system solutions required by carriers and subscribers.
Seamless compatibility to Infineon's already deployed SHDSL solutions as
well as the compatibility between all family members ensure simple
integration with current as well as future market requirements.
