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.
This latest addition to the patented, proven Aero family provides the industry's smallest, most integrated and easiest to design and manufacture DigRF transceiver for GSM/GPRS/Edge handsets, smart phones and data modems.
The Aero IIed transceiver is designed in a standard 0.13-micron CMOS process and available in a tiny 6 x 7mm package.
A complete quad-band Aero IIed GSM/GPRS/Edge radio can be implemented with only 18 components in less than 190mm2 of PCB area.

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.
Silicon Laboratories' Aero IIed transceiver integrates the RF transceiver and analogue baseband (ABB) circuitry in a small monolithic mixed-signal IC prevalidated with leading DigRF basebands to ensure full compatibility and to simplify customer design-in.
The ABB functionality integrated into the Aero IIed transceiver consists of transmit modulators, transmit and ramp DACs, front end module control, and a precise radio event controller.
The Aero IIed transceiver also includes a proven digitally controlled crystal oscillator (DCXO) and an integrated low drop out voltage regulator for direct battery connection, both of which significantly decrease bill of materials costs.
This high level of integration results in a 40% or greater PCB area reduction when compared with alternative digital interface transceiver solutions.
This not only reduces cost for the EDGE terminal manufacturer, but frees up board space to enable smaller form-factor and more feature-rich handset designs.
Along with its unique architecture, the Aero IIed transceiver also ensures the great performance customers have grown to expect from the Aero transceiver family.
The Aero IIed uses digital low-IF receiver technology to provide the industry's best receive sensitivity, which results in fewer dropped calls for consumers.
In contrast with polar architecture solutions, Silicon Laboratories' proven dual-transmit linear architecture enables superior GSM/GPRS/Edge performance and manufacturability along with the ability for customers to enjoy the flexibility and cost savings from multi-sourcing of all radio components.
Silicon Laboratories' Edge solutions are also designed to eliminate complex baseband calibrations required by competing transceiver solutions and to minimise system software changes.
"Cellular operators are beginning to aggressively roll out Edge service for subscribers", said Dan Rabinovitsj, Vice President of Silicon Laboratories.
"The Aero IIed transceiver is built on Silicon Laboratories' proven Aero family technology".
"The Aero IIed continues in the Silicon Laboratories tradition of helping manufacturers improve handset performance while reducing costs and improving manufacturability".
The Aero IIed transceiver is available in a standard 6 x 7mm 44-pin LGA package.
Pricing begins at $5.85 in quantities of 10,000.
The Aero IIed transceiver is sampling now, and an evaluationboard is available for $350.
