Atmel Introduces Industry's First 2.4-GHz DECT Non-Blind-Slot RF Transceiver IC for Voice and Data Applications.Business Editors/High-Tech Writers
HEILBRONN, Germany--(BUSINESS WIRE)---Feb. 5, 2002
Atmel(R) Corporation (Nasdaq:ATML ATML Automatic Test Markup Language
ATML Automated Test Markup Language ) announced today the availability of a high-speed RF transceiver IC for DECT (Digital Enhanced Cordless Telecommunications) A cordless phone standard mostly used in Europe; however, DECT 6.0 is increasingly used worldwide. The first DECT standards were introduced by ETSI in 1992, and DECT phones have been used as cordless home phones as (see footnote 1) applications at 2.4 GHz. The T2802 is a flexible solution for a wide range of data and voice applications such as residential cordless phones, WPBX (Wireless Private Branch EXchange) A PBX that supports cordless telephone calls. See PBX. (see footnote 2), WLL (see footnote 3) and WLAN See wireless LAN.
WLAN - wireless local area network (see footnote 4). Along with Atmel's well-known Low-Noise Amplifier/ Power Amplifier T7024, it forms a complete RF system for 2.4 GHz DECT systems.
The T2802 includes image rejection mixer, IF (see footnote 5) amplifier; FM (see footnote 6) demodulator See demodulate.
A device used to recover the original modulating signal from a modulated wave. A demodulator is also known as a detector. , baseband filter, RSSI RSSI Received Signal Strength Indicator

The on-chip Gaussian-shaped transmitter filter (with a modulation compensation circuit for advanced closed loop modulation) and a very fast phase-locked loop settling time (less than 30 microseconds) allows non-blind-slot operation, i.e. to use up to 12 handsets with the same base station. Moreover, this feature also enables industry's highest data transmit bit rates (1.152 Mbit per second) which is especially important for fast data download (wireless internet access) and fast data transfer to printers (WLAN).
"We are proud to announce with this new RF 2.4-GHz DECT transceiver a further step in high-speed digital wireless connectivity. The high data transmit bit rate will enable end users to load or send data faster than ever. Internet users will be especially happy to shorten annoying and costly download time. DECT phone customers will also enjoy the multiple hand set function that allows them to use more hand sets (up to 12) than with conventional solutions (up to 3)," said Ahmad Lindenberg, Product Marketing Manager Cordless Telephone ICs at Atmel.
The universal transceiver-to-baseband interface can be used along with any major DECT baseband IC since the transceiver is suitable for both 13.824 MHz and 10.368 MHz reference clock frequency.
A 4-bit D/A D/A
See: Documents Against Acceptance (Digital/ Analog) converter is available for pre-tuning of the VCO's center frequency to compensate for production tolerances of the IC. To achieve best performance on the receiving side, the on-board 5-bit D/A converter can be used to tune the demodulator. The DECT transceiver is completely alignment-free (i.e., mechanical tuning is not necessary).
The T2802 is designed to seamlessly interface with the RF front end IC T7024 manufactured in Silicon-Germanium (SiGe) technology. This simplifies the design, minimizes the number of external components and thus reduces production costs. The T7024 achieves an output power of +23 dBm/ 3 V at a gain of 25 dB. Its integrated LNA provides a very low noise figure (2.3 dB typ.) which together with the single-chip transceiver T2802 increases the overall sensitivity (typically -96 dBm).
Samples of the T2802 in MLP (Meridian Lossless Packing) The compression technique used in DVD-Audio that provides the highest audio quality. It delivers two channels at 192 kHz with 24-bit samples or six channels at 96 kHz. 48 pin package are available now, high-volume production has started. Pricing starts at $9.30 (10 k) for the T2802 and at $4.93 (10 k) for the T7024.
