Broadcom Releases IP Telephony Chip

Broadcom began volume shipments of a single Ethernet port IP telephony chip aimed at lower cost, basic IP phones with the look and feel of legacy, entry-level PBX phones. The new BCM1115 chip is designed for only basic phone access, with no co-resident PC requiring Local LAN connectivity via a second Ethernet port on the phone. Such phones would be used in entry-level staff offices, hallways, lobbies, classrooms and hospital rooms. Broadcom already offers a two-port version of the chip that is used in high-end IP phones. The high-end phones often feature large color displays, web browsing functions and software applications similar to those commonly utilized on PDAs. The new, one-port chip features an 87 MHz MIPS32 RISC processor and a dual-MAC digital signal processor (DSP) supporting 802.1p packet prioritization and 802.1Q VLAN identification. Two analog CODECs are capable of supporting both narrowband 8 Kilohertz (KHz) and wideband 16 KHz sampling. The chip’s integrated 10/100-Mbps Ethernet transceiver is designed and tested to withstand 2000 volts of cable-sourced electrostatic discharge (CESD), which prevents the system from being damaged or destroyed due to electric discharge. The chip is priced at $12.78 in volume.
