Interface chip brings carrier values to
VoIP
Device combines a fully integrated dual-channel SLIC and codec in a single chip.
Silicon Laboratories has expanded its ProSLIC programmable subscriber line interface (SLIC) family with a device that combines a fully integrated dual-channel SLIC and codec in a single chip The Si3226 ProSLIC leverages Silicon Labs' patented digital SLIC architecture to achieve a globally compliant, carrier-grade SLIC complete with extensive remote diagnostic capabilities, low power consumption and the industry's clearest voice reproduction in its class

Monolithic CMOS power amp cuts GSM consumption
The Si4300 is billed as the industry's first monolithic CMOS power amplifier (PA) for GSM cellular applications.
MCU incorporates high-resolution conversion
The C8051F350 is precision mixed-signal microcontroller that integrates an eight-channel, 24bit ADC with a high-speed 8051-compatible CPU.
The Si3226 is optimised for enterprise and consumer equipment, such as voice-enabled cable and DSL modems, fibre to the premise (FTTP) optical networking units and PBXs.
In contrast to analogue-based SLICs, the Si3226 is built on a highly programmable digital SLIC architecture that provides the flexibility to support the broadest range of customer requirements.
Worldwide compliance is supported using a single hardware design and bill of materials.

Set top box processor takes soft modems onboard
STMicroelectronics licensed and integrated Silicon Laboratories' system-side silicon direct access arrangement (DAA) technology into its new STi5100 processor.
The Si3226 further combines a multimode ring generator and programmable battery-tracking DC/DC controller that enable low power operation in all line states.
The device leads the voice over IP (VoIP) industry in idle-channel noise performance achieving as low as 7dB using advanced noise reduction techniques.
Remote diagnostics have become increasingly important in VoIP equipment as operators seek to reduce network maintenance costs.
The Si3226 is equipped with a 12bit monitoring ADC and powerful DSP engine that enable fast and accurate reporting of subscriber line faults.
Fault isolation is enhanced through the support of two independent line-sensing paths per channel: one inside of the line protection and one outside.
Diagnostic tests, such as those outlined in international testing standards like GR-909, can be implemented using the Si3226 without the need for relays or dedicated test equipment.
To simplify and accelerate software development, Silicon Labs provides an extensive application programming interface (API) for the complete ProSLIC portfolio.
The API provides powerful high-level commands that take full advantage of the flexibility and capabilities offered by the Si3226 while concealing the complexity of register-level programming.
"We are bringing the features, performance and reliability of traditional carrier-grade telephony to VoIP customer premise equipment", says Dave Bresemann, Vice President of Silicon Laboratories.
"By providing an easy-to-use API with integrated diagnostics, we're helping our customers get to market faster while reducing cost and software development overhead".
Samples of the new Si3226 dual ProSLIC device are available now in 64-pin TQFPs, and samples of the Si3208 and Si3209 linefeed devices are available now in 40-pin QFNs.
A wideband version of the device, the Si3227, is also available in pin-compatible 64-pin TQFPs.
Pricing for the two-channel chipsets begins at US $5.79 in 10,000-unit quantities.
