The INCA-IP is the newest member of Infineon's
advanced telephony family of products for digital
telephones. This single-chip solution is cost-
optimized for VoIP terminals featuring conferenc-
ing and hands-free functionality with high-quality
audio performance. The INCA-IP offers advanced
features such as integrated voice codecs, con-
ferencing functionality, advanced echo-cancella-
tion, as well as a full-featured telephony analog
front end (AFE). These voice features are com-
plemented by a full-fledged 3-port Ethernet
switch with packet prioritization for Quality of
Service.
Additional features include an integrated switch,
10/100BaseT Ethernet PHYs, support for power
over LAN, AFE, and DSP. The INCA-IP also offers
advanced security and supports the DES/3DES/
AES standards.
Designed for terminal systems with microphone,
loudspeaker, handset and headset inputs, the
INCA-IP offers a comprehensive single-chip IP
telephony solution.
