Silicon Laboratories (News - Alert) has extended the ProSLIC programmable subscriber line interface (SLIC) family, the Si3226 Dual ProSLIC, a fully-integrated dual-channel SLIC and codec
in a single chip.
Leveraging Silicon Labs’ patented digital SLIC architecture the Si3226 ProSLIC can achieve a globally-compliant, carrier-grade SLIC boasting extensive remote diagnostic capabilities, low power consumption and clear voice reproduction. The solution is optimized for enterprise and consumer equipment, such as voice-enabled cable and DSL modems, fiber to the premise (FTTP) optical networking units and PBXs.
The Si3226 is built on a highly-programmable digital SLIC architecture that provides the flexibility to support the broadest range of customer requirements. A single hardware design and bill-of-materials supports worldwide compliance.
The solution combines a multimode ring generator and programmable battery-tracking dc-dc controller that enable low power operation in all line states. Using advanced noise reduction techniques, the device delivers ideal idle-channel noise performance achieving as low as 7 dBrnC.
Through its 12-bit monitoring ADC and powerful DSP engine, the Si3226 enables fast and accurate reporting of subscriber line faults. Support provided by two independent line-sensing paths per channel enhances fault isolation. Using the Si3226, diagnostic tests, such as those outlined in international testing standards like GR-909, can be implemented without the need for relays or dedicated test equipment.
Silicon Labs provides an extensive application programming interface (API) for the complete ProSLIC portfolio, accelerating software development.
Leveraging the flexibility and capabilities offered by the Si3226, the API provides powerful high-level commands as well as conceal the complexity of register-level programming.
“We are bringing the features, performance and reliability of traditional carrier-grade telephony to VoIP customer premise equipment,” said Dave Bresemann, vice president of Silicon Laboratories in a statement.
