Beschreibung

The SDFE-4/2/1 V2 are the members of Lantiq’s 3rd generation SOCRATES™ family of SHDSL transceivers designed for TDM applications.The SDFE-4/2/1 V2 features full compliance with the ETSI TS 101524 and the ITU G.991.2 (G.SHDSL/G.SHDSL.bis) standards. Advanced system functionality and cost saving features continue to provide signifi cant low BOM advantages in the SOCRATES™ tradition. These features, in combination with an unprecedented power consumption of approximately 500 mW per channel, and a very small footprint, make the SDFE-4/2/1 V2 excellent solutions for remote powered repeater designs.
