The BCM1190 enables manufacturers to build feature-rich, high-quality IP phones at affordable cost points. The chip’s high-performance enhanced-RISC processor supports Broadcom’s field-proven PhonexChange™ IP telephony software suite. PhonexChange includes a wide variety of narrowband and wideband voice coders, including Broadcom’s high-fidelity BroadVoice® coder, a high quality full-duplex speakerphone algorithm, advanced jitter buffer management and packet loss concealment techniques, and a complete library of standard telephony algorithms required for IP phone designs. The RISC processor further allows customers to add product- differentiating application software. The BCM1190 integrates key Ethernet IP phone components including two 10/100BASE-T Ethernet MACs and PHYs, a wideband-capable analog codec (coder/decoder) with integrated amplifiers, high-speed serial port, UART, GPIO, and keyscan controller. The chip supports serial Flash and a 208-pin MQFP package enabling an optimized 2-layer PCB layout. The high level of integration on the BCM1190 results in low bill of material (BOM) costs. Combined with the PhonexChange software suite, this integration enables phone vendors to build enterprise-class products for the residential market at economical price points.
