Infineon Technologies AG has introduced a single-chip VoIP engine with integrated codec and analogue telephony interface, touted to be the first of such product.

The company said the Vinetic-Plus paves the way for highly compact and portable VoIP-telephony adapters that allow any analogue phone to establish VoIP calls from any broadband Internet connection.

Compared to existing solutions, Infineon said its new VoIP engine reduces the PCB area required for an adapter by at least 30 per cent. For example, the PCB area for a 2-channel foreign exchange station VoIP system using Vinetic-Plus measures just 40-by-48mm. In addition to the VoIP processor, complete subscriber line interface (SLIC) functionality is integrated into the chip, eliminating the separate analogue interface circuit or codec required for current chip-based designs.

"With Vinetic-Plus, we are extending the reach of VoIP to ultra-portable and wireless adapters and gateway products for residential and small office/home office environments," said Christian Wolff, senior VP of the Communication Solutions Business Group and general manager of the Wireline Access Business Unit at Infineon.

With Vinetic-Plus as the basis of miniaturized analogue telephony adapters, Infineon said travelers will be able to easily place VoIP calls from anywhere in the world, from any broadband access connection. The integrated chip includes DSP, memory, codec and dual SLICs to support standard telephony features such as caller ID, call hold and three-way conferencing.

The market for VoIP access devices is growing dramatically, with the total number of VoIP subscribers estimated to increase from approximately 3.5 crore (35 million) in 2006 to as many as 10.4 crore (104 million) in 2010. With its Vinetic family, Infineon said it is offering equipment manufacturers multiple devices to support product lines that address different market segments while reusing software code and protocol stacks to shorten time to market and simplify engineering.

The new solution supports 1- or 2-channel analogue telephone interfaces, as well as 4-channel VoIP, G.711, G.723.1, G.726 ADPCM, G.729A/B, iLBC coding and T.38 fax.

The Vinetic-Plus comes in a PG-LBGA-144 (green) package and is already sampling.
