per board. The capability to set through software
programming for both AC and DC line parameters makes
this the optimum solution to be easily adapted to different
country requirements. This solution is the best approach for
customers that target different markets with the same
hardware.

The STLC5048 is a fully software programmable, DSP
based, four-channel CODEC that provides the
standard CODEC functionality of the STLC5046 plus
impedance synthesis, echo canceling and frequency
response. In a TQFP64 package, it’s a single 3.3V
supply solution that also allows programming of the
SLICDC current limitation and off hook threshold of
the STLC3080. A dual PCM port is available.

Short loop applications
Thanks to new techniques of voice transport like VoIP and
VoDSL, short loop applications are becoming more and
more interesting for traditional devices like SLICs and
CODECs. For this reason, STMicroelectronics is fully
committed to providing new solutions for these
applications. Within this segment, we can differentiate
multi-line applications like integrated access device (IAD)
or VoIP systems for the SOHO (small office home office)
market and single/dual line application like Wireless local
loop (WLL) and VoIP systems for residential markets
(home access gateway).
The STLC3080 in a kit with the STLC5048 provides
an extremely space efficient solution thanks to the
further reduced number of external components.
