Broadcom announces high-density VoIP DSP

At Broadband World Forum, Broadcom announced a new high-speed VoIP digital signal processor.The new processor, called the BCM6515, targets next-gen OEM designs of multi-service access nodes (MSANs), IP digital subscriber line access multiplexers (IPDSLAMs) and deep fiber multi-dwelling units (MDU).

The BCM6515 is designed to enable low-cost, hiqh-quality VoIP for easy bundling with high speed internet, IPTV and converged wireless services. Its features include high-speed voice coding, voice compression, IP processing, and embedded adaptive jitter buffering with direct uplink network connectivity, according to Broadcom's release. A high-density design enables encoding of up to 72 complex voice streams.

As is typical, Broadcom has also announced a reference design for OEMs. The BCM96515 reference design is a joint collaboration between Broadcom and Zarlink and includes VoIP DSP processing, a Broadcom Gigabit Ethernet transceiver chip, and Zarlinks VoiceEdge next generation carrier chip set to provide audio line processing with integrated testing, SLIC circuits, and a multi-port voice control processor to provide real-time call control functions.
