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.
Under the licensing agreement, Silicon Laboratories will supply the Si3070 DAA line side device to STMicroelectronics' customers enabling a single-chip soft modem for low-speed applications.
The new Si3070, one of Silicon Laboratories' embedded line-side products, is pin compatible with existing line-side devices used in the company's market-leading ISOmodem hardware modem solutions.
This enables customers to implement a single layout to support all speeds of hardware and software modems without redesigning the system, maximising design flexibility while minimising the risk of transitioning from hardware to software modems.

Analogue front end supports ADSL2+ datarates
The Si3110 is heralded as the industry's smallest, high-performance, integrated analogue front end (AFE) for ADSL and ADSL2+ applications.
The embedded line-side DAA family leverages Silicon Laboratories' proven DAA technology to achieve global compliance, dramatically reduce the number of discrete components and simplify modem design.
"We have leveraged our market leading ISOmodem products and silicon DAA technology to enable the transition to soft modem technology in set-top boxes", said Dave Bresemann, Vice President of Silicon Laboratories.
"The success of soft modem technology has been proven in the PC market, where, like the set-top box market, price, performance and ease-of-design are key factors in the success of the technology".
"Silicon Laboratories is a leader in silicon DAA technology and our joint solution offers leading-edge integration to simplify set-top box design for our customers", said Chris Carter, Marketing Manager of the Satellite and Terrestrial Business Unit of ST's STB Division.
"The availability of powerful processor technology enabling soft modem support creates a new model for set-top box connectivity based on high-performance, affordable technology".
Silicon Laboratories' Si3070 DAA is specifically engineered for cost sensitive, low-speed embedded modem applications.
All devices in Silicon Laboratories' embedded line-side product family offer a programmable line interface to meet global telephone line interface requirements and eliminate the need for the analog front end, isolation transformer, relays, optoisolators and two- to four-wire hybrid.
The Si3070 is available in a 16-pin small outline package.
Samples are available now, and volume production will begin in the third quarter of 2004.
