SI3225 Datasheet (si3220 / Si3225) Dual Proslic Programmable CMOS Slic/codec

Manufacturer: Silicon Laboratories

Overview: .. S i 3 2 2 0/25 DUAL PROSLIC® PROGRAMMABLE CMOS SLIC/CODEC.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The Dual ProSLIC® is a series of low-voltage CMOS devices that integrate both SLIC and codec functionality into a single IC to provide a plete dual-channel analog telephone interface in accordance with all relevant LSSGR, ITU, and ETSI specifications.

The Si3220 includes internal ringing generation to eliminate centralized ringers and ringing relays, and the Si3225 supports centralized ringing for long loop and legacy applications.

On-chip subscriber loop and audio testing allows remote diagnostics and fault detection with no external test equipment or relays.
