Si3226x Dual ProSLIC Family Reduces Cost, Board Size and Power
Consumption for Wide Range of VoIP Customer Premises Equipment
AUSTIN, Texas--(BUSINESS WIRE)--
Silicon
Laboratories Inc. (NASDAQ: SLAB), a leader in high-performance,
analog-intensive, mixed-signal ICs, today announced the industry's most
integrated, cost-effective and power-efficient subscriber line interface
circuit (SLIC) solution for voice-over-IP (VoIP) gateways. The new
Si3226x Dual ProSLIC® family delivers the smallest bill of materials and
board area and the lowest power consumption of any dual SLIC available.
The Si3226x family provides an ideal solution for low-channel-count VoIP
customer premises equipment (CPE) such as fiber to the home (FTTH)
gateways, DSL integrated access devices and cable embedded multimedia
terminal adaptors (EMTAs), as well as high-channel-count products
including multiple-dwelling-unit gateways and PBX systems.
According to Global Industry Analysts, FTTx deployment is expected to
reach 183.9 million subscribers by 2015, with more than 80 percent of
the roll-out occurring in Asia. The need for higher bandwidth to support
IPTV and video-on-demand services, growing demand for bundled
voice/data/video services and aggressive plans to upgrade copper
networks to fiber-optic cable are driving the growth of the FTTx gateway
market. Silicon Labs' Si3226x Dual ProSLIC family is designed to help
reduce the cost and complexity of these gateways.
FTTx and other VoIP gateway manufacturers are challenged to fit all the
functionality demanded by subscribers into small, inexpensive system
designs. The Si3226x SLICs address this challenge by providing two
complete channels in a tiny 60-pin 8 mm x 8 mm QFN package. The tiniest
dual foreign exchange station (FXS) solution available, the Si3226x
devices enable the lowest BOM cost and smallest footprint per channel
for multiline gateways, even smaller than some quad- and octal-channel
FXS solutions.
The Si3226x family is the industry's first FXS solution containing an
integrated level shifter/driver that allows a direct connection to a
dc-dc converter's power transistor regardless of input voltage. This
innovation eliminates the need for the MOSFET pre-drive circuit required
by competing SLIC designs, reducing the cost and footprint of a
two-channel design by at least twelve external devices.
The Si3226x family sets a new benchmark in minimizing total FXS system
power consumption, requiring less than 55 mW per channel when on-hook,
making the Dual ProSLIC devices an ideal solution as telecommunication
service providers and governments mandate more energy-efficient
electronic products. The on-chip intelligent dc-dc converters optimize
energy efficiency by generating only the voltages needed in on-hook,
off-hook and ringing states. Ultra-low power consumption makes it easier
to meet green energy requirements such as the European Commission's Code
of Conduct on Power Consumption for Broadband Equipment; enables longer
battery standby time in battery-backed designs; and reduces heat
dissipation, eliminating the need for fans in multiline gateway designs,
further reducing system cost.
The Si3226x family is designed to generate tracking batteries for lowest
power consumption, as well as work with shared battery supplies (e.g.,
fixed-rail) for the lowest BOM cost. The integrated dc-dc controllers
can be configured as either single-output tracking dc-dc converters for
each SLIC channel or a single multi-rail dc-dc converter shared by two
or more channels. This flexibility allows developers to use the same
SLIC device for both low-power tracking designs and low-cost fixed-rail
designs. Furthermore, Silicon Labs' innovative tracking shared supply
(TSS) capability significantly reduces the power consumption of
two-channel shared-battery designs compared to competitive fixed-rail
designs.
"Silicon Labs continues to drive innovation in the mixed-signal
telephony IC market by increasing on-chip integration, reducing power
consumption, and shrinking BOM cost and component count with
sophisticated dual SLIC designs," said Carlos Garcia, vice president and
general manager of wireline products for Silicon Laboratories. "The
Si3226x ProSLIC family is precisely what manufacturers need to develop
the next generation of small-footprint, feature-rich and
energy-efficient VoIP gateway designs."
Silicon Labs provides software and reference design support to
accelerate time to market and simplify Si3226x-based designs. The
ProSLIC API, a common software library for the entire ProSLIC portfolio,
eliminates the need to develop system-specific software drivers for
ProSLIC devices. To allow system designers to optimize the tradeoff
between cost and power consumption, the Si3226x evaluation boards
support multiple dc-dc converter options. To further ease design
challenges, reference design hardware and software support is available
from leading vendors of system-on-chip (SoC) solutions for VoIP gateway
equipment.
Pricing and Availability
Silicon Labs offers two versions of the Si3226x Dual ProSLIC devices:
those that connect to standard PCM/SPI digital interfaces or optionally
to Silicon Labs' three-wire Integrated Serial Interface (ISI). The
Si32260/1 standard PCM/SPI devices are available now in an 8 mm x 8 mm
60-pin QFN package. Additionally, the Si32266/7/8/9 devices are
available in a 6 mm x 8 mm 50-pin QFN package and use Silicon Labs' ISI
to reduce the interconnect to selected VoIP broadband gateway SoC
solutions from several major vendors. Si3226x family pricing begins at
$5.31 (USD) in 10,000-unit quantities. For more information or to
