Atmel Introduces Highly Integrated Low-IF SiGe-BiCMOS Transceiver IC for 2.4 GHz Digital Cordless Telephones Enabling Operation of Multiple Handsets

Heilbronn, Germany, November 29 (ots/PRNewswire)

- New Chip Offers the Industry's Best Sensitivity Values for Long
Distance Coverage
Atmel(R) Corporation (Nasdaq: ATML), a global leader in the
development and fabrication of advanced semiconductor solutions,
announced today the availability of its new 2.4-GHz transceiver IC
ATR2806 manufactured using Atmel's advanced SiGe BiCMOS process. The
new ATR2806 is especially designed for digital cordless telephone
applications, but can also be used for wireless data applications
such as wireless Internet access, headsets, games and home
entertainment. This new low-IF device provides several unique
features such as multiple handset operation and long distance
coverage due to its excellent sensitivity (-93 dBm at full data
transmit bit rate of 1.152 Mbit/s).
The ATR2806 is a highly integrated transceiver, which includes in
the receive path a low-noise amplifier, image rejection mixer, low-IF
filter, demodulator, RSSI and RX data as digital signal. It also
includes a fully integrated VCO and PLL with an integrated Gaussian
filter. Due to the high integration, only a few components are needed
to design the RF section of a cordless telephone. SAW filtering,
matching components, IF tank circuitry, and demodulator tank are not
needed. The circuit also provides a digital receive signal, thus
eliminating the need for any external data slicer.
The IC has a flexible interface to the baseband, so any standard
DCT baseband IC can be used. Various data transmit bit rates are
supported (1.152 Mbit/s and 576 Kbit/s).
Another main benefit is the IC's outstandingly high sensitivity of
-99 dBm. This is a value not reached by any competing product;
standard values are usually up to -94 dBm. This allows coverage of
longer distances (about 300 m). The new architecture also enables
longer talk and standby time compared to conventional concepts.
Thanks to the ATR2806's fast-settling PLL, the base station can
support up to 10 handsets (multiple handset function), whereas
competitive products, using fixed data transmit rates, can only
handle up to a maximum of 4 handsets.
To support design-in, demo boards with documentation, test
results, schematics and Gerber files are also available.
Samples of the low-IF transceiver IC ATR2806 in QFN32 packages are
available now. Pricing starts at 4.00 US$ (10 k).
