Dual-Port Ethernet Server Adapter

Currently Viewing:

Designed for today's enterprise and data center environments, Broadcom's NetXtreme® Ethernet Adapters are the ideal solution for multicore servers, delivering full line-rate throughput across all ports.
The chip integrates a Gigabit Ethernet (10/100/1000 Mb/s) switch and two fast Ethernet (10/100 Mb/s) transceivers, allowing for the development of traditional fast Ethernet IP phone designs without the additional cost of adding external transceivers. With the addition of external Gigabit Ethernet transceivers, manufacturers can easily upgrade their designs to create Gigabit Ethernet IP phone models. The chip's high-performance RISC processor and DSP support 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™ codec, 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 BCM1103 is the world's first IP phone chip that incorporates Gigabit Ethernet (GbE) switching, hardware security, advanced quality of service (QoS) techniques and increased processing performance in a single chip, enabling full-featured desktop IP phones.
