Silicon Laboratories' broad array of mixed-signal communication devices brings
unsurpassed integration, performance and value to broadband access and voice
telephony solutions. These integrated circuits provide global compliance using a single
hardware solution while reducing the PCB footprint and total solution bill-of-materials.
Optimized for customer premise equipment (CPE) applications, these best-in-class
solutions address global telecom standards through a high degree of programmability.
Additionally, these products are designed using standard digital CMOS. This reduces
power and cost while increasing system performance and flexibility through increased
integration without sacrificing system performance.

Si3216 ProSLIC
The integrated SLIC, codec and
dc-dc converter provides a
globally-compliant, modular
telephony interface requiring only
a 3.3 V or 5 V power supply. The
patented on-chip tracking battery
supply eliminates custom power
supply design and
reduces power in all
operating modes.
Si3110 ADSL2+ AFE
Provides higher data
transfer rates and
longer reach for
ADSL applications.
Si2457 ISOmodem
Provides a complete embedded
modem family for up to 56 Kbps
applications. Ideal as a backup
modem or for remote provisioning
and diagnostics access.
With its fully programmable SLIC, codec functions and global compliance, the Si3216 ProSLIC is the ideal solution for adding voice capability
to an existing broadband modem or for creating a full-featured Voice-over-Broadband (VoB) solution. The Si3110 delivers industry leading
ADSL performance in the smallest footprint by integrating the line driver, DAC, ADC, filters, VCXO and hybrid. The Si2457 provides a fully
integrated V.90 modem for broadband backup, provisioning or remote system configuration. The Si3050 offers a globally-compliant interface
to the switched network for emergency "911" calling and other standard telephony features.
