Plymouth Meeting, PA, United States, 2012/11/06 - Adaptive Digital has leveraged its field proven VoIP software and the highly integrated Texas Instruments Stellaris LM3S9D96 microcontroller to bring high quality IP telephony to ultra-low cost IP phones and analog terminal adapters (ATAs).
Used in both types of equipment, the Stellaris LM3S9D96 ARM® Cortex™ M-3 microcontroller brings with it not only an ARM CPU but also on-chip flash memory, RAM, and an Ethernet MAC and PHY. That’s almost as integrated as an IP phone chip can get. The Cortex-M3 is capable of running the Adaptive Digital’s complete IP Phone application, including SIP, STUN, UDP/IP, RTP, G.711, G.729AB, and acoustic echo cancellation, using only on-chip flash memory and RAM.
By adding a Silicon Labs Si32178 ProSLIC®, the low-cost advantage extends into the ATA market. The ProSLIC, also highly integrated, combines an FXS interface, codec, tone detection and generation, caller ID, and protection circuitry on a single chip. Plus, it has a SPI interface that can connect directly to the Stellaris SPI interface.
Adaptive Digital’s ATA and IP Phone software applications share a similar base set of protocols and algorithms while separately addressing the features that are unique to these two solutions. Adaptive Digital is currently demonstrating both solutions using the TI Stellaris EVM board (DK-LM3S9D96) and the Silicon Labs SLIC EVM (Si32176PB10SLO-EVB.) IP Phone and ATA equipment manufacturers can leverage existing reference circuitry on these EVM boards to speed up their hardware design. Similarly, Adaptive Digital’s sample IP Phone and ATA applications are available in source code format to enable equipment manufacturers to leverage existing software and still customize it as needed. Adaptive Digital’s protocol stacks and algorithm libraries are available in object code format. You take the schematics and software and mold them into a market ready product.
The Stellaris® ARM® Cortex™ M-3 microcontroller brings high-performance 32-bit computing to cost-sensitive embedded microcontroller applications. It is because of the high degree of integration that the Stellaris achieves that drives down the manufacturing cost of the IP phone and ATA. In the same way, the ProSLIC helps reduce the manufacturing cost of the ATA. In addition by leveraging Adaptive Digital’s field proven VoIP solutions, developers significantly reduce development time. This is a win-win combination. Stellaris (reduced manufacturing costs) + Adaptive Digital (field proven VoIP algorithms) = Low-Cost VoIP Solutions.
