The support tools for the ATR2740 System-on-Chip
IC include Atmel Digit Receiver API Software, which
can be used to control the complete DAB system.
The IC is also supported by a full suite of documents
including datasheets and application notes. A DAB
Evaluation Kit (ATR2732-40DEV-Kit1) is also avail­able to support easy design-in of the DAB base­band processor ATR2740. This kit includes digital
broadcast receivers, power supply, antennas, loud­speakers, and supporting software. While this kit
has been designed for evaluation of audio, video,
and data services, it can also be used for drive
tests. For further information, please contact your
local Atmel sales team or any Atmel distributor.

 All IF Inputs from 2 to 50 MHz Supported
 Perfect Combination with DAB Front End

ATR2732

 Audio Decoding of Musicam and MPEG2 Layer
