Atmel Boosts Cordless Phone Operating Distance by Introduction of New 2.4-GHz DCT Chip Set
Wednesday June 25, 8:00 am ET
Industry's First Wireless Solution That Can Handle Up to 10 Handsets
HEILBRONN, Germany, June 25 /PRNewswire/ -- Atmel® Corporation (Nasdaq: ATML - News)
announced today the availability of a new 2.4-GHz DCT chip set, consisting of the LNA/ PA IC
T7026 and the transceiver IC T2803. It is especially designed for cordless phones, while also
being used for wireless data applications such as internet access, wireless headsets, games
and home entertainment. This new chip set enables an extended distance between the handset
of a cordless phone and the basestation. Current solutions can bridge a distance of usually
300 meters, this new chip set can reach up to 600 meters.
This chip set offers the wireless systems designer outstanding flexibility. The T2803's variable
data transmit bit rate allows to adjust to any data transmit bit rate in a range of 9.6 kbit/s to
1.152mbit/s. This results in an excellent sensitivity, reflected in the lab-tested sensitivity at
1.152 Mbit/s of -95 dBm, and at 576 kbit/s of about -98 dBm. This enables the base station to
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.
The T7026 provides a power output of 28 dBm and includes a power control system, which can
be controlled by the software to reduce the current consumption. "On top of the exciting
distance extension and the multiple handset function, customers will enjoy the extended
operating time due to the low current consumption," said Ahmad Lindenberg, Marketing
Manager Cordless Phone ICs at Atmel.
For the transceiver IC T2803, an open-loop modulation architecture has been used since many
customers have in-depth experience with this modulation scheme.
For cordless phone applications, any DECT baseband controller is suited to operate along with
the new chip set. For wireless data applications, a baseband controller, e.g. Atmel's AVR®
microcontroller, can be used.
Samples of the new 2.4-GHz DCT chip set in QFN48 (T2803) and QFN20 (T7026) packages
are available now. Pricing starts at US$5.70 (T2803, 10 k) and US$2.80 (T7026, 10 k).
