Atmel Introduces Industry's First DAB One-Chip Baseband Processor With Full Decoding Rate Capability
HEILBRONN, Germany----Sept. 15, 2000--Atmel
Corporation (Nasdaq:ATML), released today a highly integrated one-chip
baseband processor for Digital Audio Broadcasting (DAB). The new IC
U2739M is industry's first one-chip decoder featuring full decoding
rate capability.
The U2739M is an integrated circuit in advanced CMOS technology
for demodulation and decoding of the DAB bit stream data according to
ETS 300 401. It is the only available one-chip solution that is
capable to perform a full decoding rate of 1.82 Mi bits/s (max.). This
enables a car radio to receive -- in addition to the audio data --
also further services like messages, electronic newspapers, videotext
information and special offers to take advantage of DAB's full
possible impact.
The new baseband processor is highly integrated, both the channel
and the source decoder are on-chip. This outstanding feature helps to
reduce the number of external components and allows the production of
compact designs. The channel decoder part includes the main features
of the OFDM demodulation/decoding as well as the time/frequency
synchronization algorithms, using the embedded OAK DSP Core. The
source decoder consists of an audio source decoder (supporting ISO
MPEG 1,2 layer 2) and the data decoder part which provides two
independent packet mode decoders. Several standard interfaces like
I2C/L3, I2S or RDI are implemented to enable maximum flexibility.
To furthermore increase flexibility, the U2739M enables the
customer to use his own software instead of the existing one. Software
modules can be replaced or extended by means of a special boot mode.
Time and frequency synchronization modules, for example, can be
replaced by downloading the corresponding user software algorithms to
the OAK DSP core.
The U2739M completes Atmel's DAB front-end chip set which is a
highly sophisticated 3 chip DAB system solution. This chip set covers
all analog and digital functions of a DAB receiver -- no adaptation or
adjustment by the customer is necessary. Due to the high integration,
only few external components are required and production costs can be
reduced. This enables customers to manufacture highly sophisticated
car radios fast, easy and cost-effective.
``As industry's first manufacturer to offer an entire DAB system
solution, Atmel has a leading position on the DAB market,'' states Dirk
Kleffmann, Product Line Manager at Atmel Wireless & Microcontrollers.
``And this new highly integrated and highly flexible baseband processor
is the first such product that lets end users really enjoy the full
range of different services DAB provides.''
Samples of the U2739M are available now. To support the design-in,
Atmel offers a complete DAB evaluation kit (comprising the RF front
end evaluation board, an interface board with microcontroller and A/D
converter and a baseband evaluation board with the U2739M). Pricing
for the U2739M starts at US $24.00 (100k).
