Broadcom delivers first single-chip IP phone solution
Broadcom Corp. has announced the BCM1100 Internet Protocol Phone Engine, the world's first single-chip solution for enabling Ethernet IP telephones.
The BCM1100 will enable manufacturers to deliver IP phones with the features and price levels required for large-scale deployment of desktop IP telephony.
The BCM1100 integrates a number of unique features into a single chip. An Ethernet switch guarantees voice priority, and enables the office PC and IP phone to share a single LAN connection, eliminating the expense of a second LAN drop. The BCM1100 also includes two Ethernet transceivers, and analog codecs for handset and speakerphone support. This additional silicon integration will enable the lowest power IP phones in the industry, making power over Ethernet cabling a practical reality, says the company.
In addition to integrating a RISC processor core for protocol handling and a DSP core for signal processing, Broadcom's BCM1100 design incorporates an Ethernet switch and two Ethernet transceivers, enabling it to receive, prioritize, process and play or forward packets of voice and data over existing corporate 10/100 Base-T networks.
