| Silicon Laboratories Issues Aero IIed Single-chip EDGE Transceiver Silicon Laboratories has announced the Aero IIed single-chip EDGE transceiver with a digital interface. The Aero IIed is fully compliant with the 2.5G DigRF specification version 1.12 and is pre-validated with leading DigRF baseband implementations. 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 7 mm package. A complete quad-band Aero IIed GSM/GPRS/EDGE radio can be implemented with only 18 components in less than 190 mm squared of PCB area. Silicon Laboratories' Aero IIed transceiver integrates the RF transceiver and analog baseband (ABB) circuitry in a small monolithic mixed-signal IC pre-validated 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 percent 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 high 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 minimize system software changes. write your comments about the article :: © 2006 Networking News :: home page |
