C O N T A C T I N F O R M A T I O N
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.

Si3050 Voice DAA
The small footprint of the Si3050 DAA provides a full-
featured interface to the switched network while maximizing
port density. This globally compliant solution allows one
board to be shipped worldwide without changing any
external components. Standard telephony digital interfaces
allow simple integration into any voice application.
