AUTOMOTIVE RADIO TUNERS--MT1503EDC DAB/DMB TUNER

The MT1503EDC is a tuner
module for reception in VHF Band III
and L-Band compliant to the DAB
EUREKA 147 standard. It performs a
down-conversion to an intermediate
frequency followed by further signal
processing based on an integrated
baseband processor. A serial bus
interface serves as a digital audio
output.
In order to minimize interferences
and distortion caused by undesired
signals of adjacent channels the
tuner section of the MT1503 features
digitally aligned tracking filters and
an IF SAW filter. The integrated flash
memory stores the necessary
alignment data and the software for
the baseband processor.
The MT1503EDC supports a
variety of possible applications by
decoding FIC/FIDC and PAD data
which is used to broadcast dynamic
labels, traffic information,
slideshows, websites as well as
information needed for station
following and announcement
switching. A standardized Raw Data
Interface (RDI) and a Serial
Peripheral Interface (SPI) grant
access to the full DAB audio and
data stream to enable an easy
connection of external decoders for
additional data services and mobile
TV applications. All tuner and DSP
functions are controlled by a
Universal Synchronous/
Asynchronous Receiver/Transmitter
(USART) interface.
Active antenna systems as
commonly used for automotive
applications can be fed with 12V
phantom power which is routed from
a pin connector to the antenna input
of the module.
The MT1503EDC is lead free and
fully complies with RoHS
requirements. It has been optimized
to meet the specific requirements for
automotive applications and provides
reliable performance even under
harsh environmental conditions like
temperatures from -40
