Atmel Broadcast Radio User Manual
The fl exibility of new digital radio broadcasting systems enables the provision of a wide range of media
services to the end user; the most frequent of which are data services running in parallel to the typical audio
service. The system stack of the Eureka-147-based digital radio (which includes DAB, DAB+, or T-DMB)
typifi es this fl exibility by supporting the implementation of a wide variety of services, while providing a plat-
form for the development of future services.
Atmel
®
offers a complete DAB solution, which includes an RF front end and a DAB-decoding baseband.
The ATR2740 DAB baseband processor is a highly functional system-on-chip solution. Its fl exibility enables
the implementation of application-related tasks. This chipset forms the hardware basis for the Digital Radio
Box, Atmel’s verifi cation and visualization tool for data-based services.
Dimensions: 105 mm × 84 mm × 38 mm
USB port on front for connection to the external
host PC or laptop. Power can also be supplied
through this USB interface
Antenna connection points for looping into an
existing antenna system
Optional 12V DC connection
The Digital Radio Box is a fl exible and effective
tool, designed primarily for the demonstration and
monitoring of data service applications. While it is
not optimized for audio listening, it can be used for
this purpose. The Digital Radio Box can be easily combined with external hardware (for example,
navigational systems) for the provision of TPEG or
Journaline
®
services. Users can also create custom-
ized PC-based software to demonstrate other data
services as the Digital Radio Box, after decoding,
streams out TPEG or Journaline related data groups
to the host PC or laptop.
The Digital Radio Box is also perfectly suited for
users interested in prototyping and testing or simply
acquainting themselves with the data services provided via digital radio.
