SDSL One Chip Rate Adaptive
Transceiver with Embedded
Start-up
The one chip transceiver IC SOCRATES
TM
inte-
grates all functions of a SDSL transceiver accord-
ing 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 control-
ler 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.
