 Infineon’s EASY 21653 Phone is a vertically integrated GbE IP Phone HW and SW reference design. This represents an unprecedented opportunity for system developers to design IP Phones in a far shorter design window, and to concentrate on their real added value. It includes a complete set of voice firmware containing all of the voice processing codecs as well as algorithms for Acoustic Echo cancellation and Handset Echo Cancellation. Customers can test every HW interface using the delivered phone. Moreover they can test their model specific options by means of the Adapter-Board. The Phone runs a complete Infineon developed SPINACER IP PHONE SW suite including a SIP stack and application as well as all other IP Phone relevant SW on a Linux Operating System. Customers can test every HW interface using the daughter board as well as use keyboard, Colour TFT Display and all other important IP Phone features.The comprehensive IP Phone SW suite contains an optimized SIP stack devloped by Infineon based on Open Source Linux. 下图是PSB 21653 E - INCA-IP2的外形图.  INCA®-IP2 is Infineons second generation of IP Phone terminal chips, and the 5th generation of PBX phone devices. Enabled by two powerful 400 MHz MIPS CPU’s and an internal Gigabit Ethernet switch it represents a quantum leap for IP Phones in the Telecommunication network. Typically an IP Phone is not the end point of the IP networks architecture and as such should not represent a bottleneck for a Gigabit Ethernet Network. INCA-IP2’s dual core approach offers a tremendous opportunity to IP Phone manufacturers to differentiate their phones in an increasingly competitive environment. The INCA-IP2s powerful engine turns the IP Phone into an IP appliance enabling a slew of voice and multimedia features, making it possible to offer low to high end phones based on one platform. Phone makers can consider adding AMR, LEC, AEC, T.38, MP3 decoding, MiDi Synthesizer and even streaming video to their feature sets. 芯片应用: IP Phones and Video Phones WLAN base-stations Network Fax Machines CPU特性: 400 MHz MIPS 24KEc CPU 16kB Instruction and 16kB Data Cache DDR-SDRAM Controller, NAND and NOR Flash support Support for 16 bit instruction encoding (MIPS16e ASE) for code size reduction 语音处理特性: 400 MHz MIPS 24KEc voice engine with DSP application specific extensions Voice Coding G.711,G.723.1, G.729A/B, G.722, G.722.1, iLBC, AMR, Two D/A and A/D converters for in call announcements and other applications Advanced acoustic echo cancellation for full duplex speakerphone, three-party conferencing with mixed codecs Handset echo cancellation Voice Activity Detection Speech Recognition w w w. i n f i n e o n . c o m / v o i p 以太网特性: Full 3 port Gigabit Ethernet Switch with two GMACs and RGMII interface for optional connection of external GPHYs Two integrated 10/100BaseT Ethernet MACs and PHYs for LAN and PC connection 802.1p & Q standard compliant Sophisticated Policy and Flow Engine supporting up to 24 flows, based on L2 to L7 information, allowing leading edge traffic classification Flexible Traffic Management Support for up to 4 priority queues, enabling time-sensitive data to have access to the network with minimal delay 接口和端口: USB2.0 Full/Low Speed Host Two SSC (synchronous serial interface), SPI compatible, EBU: parallel 8/16 Bit Interface PCM interface including FIFO, AC97 codec interface Memory controller supporting SDR and DDR1 SDRAM Two ASC/UART supporting IrDA Under voltage detection (UVD) with power on reset functionality saves external POR Real time clock (RTC), optionally with separate oscillator connection for low power mode 数据加密单元: Powerful HW-accelerator to support encryption (DES/3DES, AES) and hashing (SHA-1, MD5) True Random Number generator 802.1x Authentication The INCA-IP2 comes with a complete SIP Phone HW and SW reference design using Infineon-developed software.This includes a comprehensive set of voice codecs, as well as network, SIP Protocol and VoIP related features. In addition developers will be familiar with the EASY 21653 Board support package with a complete set of device drivers,Linux kernel 2.4.2 as well as a HW reference design with full acoustic support.
