Working with Hellosoft, a provider of communication intellectual property, BridgeCo announced a new reference design that promises to enable consumer electronics OEMs and ODMs to quickly develop cost-effective, secure VoIP (voice-over-Internet Protocol) atas (analog telephone adapters). Consumers can plug any type of conventional telephonewired or cordlessinto the RJ-11 jack of an ATA to make free and low-cost domestic and international VoIP telephone calls through the Internet, explained BridgeCo.

According to the press release, the reference design is the first comprehensive silicon and software platform targeted at consumer electronics (CE) manufacturers that want to incorporate VoIP capability directly into audio systems, A/V systems, stand-alone digital media players, STBs and other CE devices.

"Our new VoIP reference design allows designers to develop discrete ATA products, or products that integrate VoIP functionality with Internet audio streaming and MP3 file sharing," said BridgeCo Founder and CTO Christof Heidelberger. "Coupled with BridgeCo's comprehensive SDK and intuitive APIs, designers have enormous flexibility to imagine and implement a range of products for a variety of CE markets and applications."

The BridgeCo platform includes a robust encryption engine and a choice of encryption protocols to provide a secure communication channel from handset to Internet. The reference design combines Hellosoft's VoIP software suite with BridgeCo's recently announced DM830 media networking processor and firmware platform. The VoIP software suite, which runs on BridgeCo's DM830 processor, incorporates G.711, G.726, G.723.1 and G.729AB vocoders, G.168-2000 Line Echo Canceller, Voice Activity Detection (VAD), Comfort Noise Generation (CNG), Jitter Buffer, Packet Loss Concealment (PLC), DTMF Tone Detection and Generation, Call Progressive Tone (CPT), SIP/RTP/RTCP Call Signaling and Control, and multi-channel system-level framework.

The DM830 processor interfaces directly to a wide variety of PHY-layer network devices, including Ethernet, HomePlug Powerline and 802.11g wireless devices. The BridgeCo firmware bundle includes a RTOS that handles TCP/IP and USB networking protocols; MP3, WMA and other audio format decompression; DTCP/IP, Windows Media Connect and other digital rights management (DRM) encryption/decryption processing and authentication; and UPnP, IR and LCD control functions.

The VoIP reference design evaluation boards are available for $499. Evaluation boards come complete with a comprehensive SDK (software developer's kit), a complete BoM, Gerber files and VoIP software modules. Advanced software modules are available for an additional fee.
