Intel PEF 21624

Description

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.

Features

• Fully integrated 4/2/1 channel transceiver solution, including DSP, microcontroller, analog front end (AFE), line driver and memory, in a single integrated chip
• Support of payload data rates from 144 kbit/s up to 15.352 kbit/s with 8 kbit/s granularity (exceeding G.SHDSL.bis)
• M-pair functionality integrated
• Tunable hybrid for optimal loop adaptation and reach
• Only a few external passive components required
• Prepared for Near End Self-Cross Talk Cancellation with separate FW

Typical applications

• Digital Loop Carrier (DLC) Systems
• ISDN primary rate access replacement
• Leased line services
• SHDSL repeater/regenerator
