In today’s world of high-speed digital communications, the traditional analog phone line still plays an important role,
providing reliable, inexpensive voice communication at a very low cost through legacy networks where bandwidth is
severely limited and noise often a problem. Serving both the central office and customer premises end of this market,
STMicroelectronics builds on decades of experience in telecom products and optimized power IC technologies to deliver
line card solutions that address the key needs of these markets.
For central offices, the need to add new services in
existing facilities increases the pressure on space and on
power consumption, making small size and low dissipation
extremely important in line cards. If more lines can be
squeezed onto a single board, then all the lines in the
office can be served using less floor space, freeing up
more for new digital equipment. In small and home
offices, the emergence of new products like home
gateways and Voice-over-IP access devices has created
new markets for line card chipsets outside the central
office. In this field, too, STMicroelectronics applies
advanced technology and design knowhow to deliver
chipsets that are programmable to meet a wide range of
standards, enabling use in many regional markets. The
same chipsets also address the needs of wireless local
loop equipment.
Central office/PABX applications
STMicroelectronics provides a new line card product
generation for this traditional application; two different
chipset are provided to meet different requirements.
STLC5046 + STLC3080
Low-cost, space saving, low-power of highly-integrated
solution that allows to development a line card exceeding
international standard requirements with a high number of
channels per board.
■
The STLC5046 is a semi-programmable four-channel
CODEC that provides standard CODEC functionality.
It’s a single 3.3V supply device that also integrates a
SLIC control interface to simplify line card design. In a
TQFP64 package, the solution provides programmable
gains and time slot assignment. In cases where the
controller is not present on the line card, the device
can be used also in pin strap mode.

STLC5048 + STLC3080
The STLC5048 and STLC3080 combine to provde a
low-cost, space saving, low-power, highly-integrated and
fully software programmable solution that allows the
development of a line card exceeding international
standard requirements with a high number of channels
The STLC3080 is a fully-featured, single-chip SLIC
characterized by a very low power consumption. It
performs TTX injection and filtering, impedance
synthesis, echo cancelling and programmable DC
characteristic, current limitation and off hook
threshold. The solution comes in a TQFP44 package,
thanks to its limited external components, providing
an extremely space, efficient solution. Requiring only
