INCA-IP One Chip IP Phone INCA-IP Version 1.1

The INCA-IP is a cost optimized solution for Voice over IP (VoIP) Telephony applications integrating all necessary functions on a single chip. The Analog front end (AFE) and the DSP provide the acoustic Interface Automatic gain control and performs voice signal processing, like echo cancellation, voice coding and compression, Tone detection and generation, and conferencing. The Ethernet module provides two physical Interfaces to the LAN and for connection of the PC and it integrates two MAC units and a 3-port Switch This module handles the voice packets from the LAN and transfers data packets between the PC and the LAN. Also network functions like flow control, voice packet prioritization, dynamic data buffering and CoS check is handled by the Ethernet module. The powerfull 32-bit MIPS CPU core is executing its software from external memory via the instruction and data caches and CAN be seen as the central control unit of the IP phone. It provides the platform for the RTOS on top of which all protocol stacks for the network Interface and the Telephony signaling are running. It also controls all user Interface functions. The CPU is executing from external SDRAM memory. The peripherals Interfaces primarily provide connection of user control functions of the telephone like keypad, Display and LEDs By Infineon Technologies Corporation
