The one chip transceiver IC SOCRATESTM integrates all functions of a SDSL transceiver according to the emerging ETSI and ITU standards. It can operate at all data rates from 144 kBit/s up to 2.3 MBit/s in 8 kBit/s granularity. Its small package and low power consumption make it especially useful in linecard and remote feed applications. The integrated microcontroller and HDLC controller make it easy to use in a variety of applications. The built-in 2B1Q mode keeps it interoperable with HDSL solutions. All features required for operation in WLL/RITL systems are available. The device is also interoperable with the MuBIC MDSL chip. Infineon also supplies a wide range of other telecom ICs to offer complete system solutions for different applications.
