Description
The Dual ProSLIC® is a series of low-voltage CMOS devices thatintegrate both SLIC and codec functionality into a single IC to provide a complete dual-channel analog telephone interface in accordance withall 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.
