Product Brief SDFE-4/2/1 Symmetric DSL Front End, 4/2/1 Channel SDFE-4, PEF 24624 E SDFE-2, PEF 22624 E SDFE-1, PEF 21624 E Loop Interface The SDFE-4/2/1 are the latest members of Infineon's 2 nd generation SOCRATES (R) family of SHDSL transceivers designed for pure TDM applications. The SDFE-4/2/1 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 significant 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 excellent solutions for remote powered repeater designs.
