Texas Instruments (TI) delivers thefirst open, software-driven EurekaDAB digital radio receiver solution.This enables the most cost-effectiveand power-efficient products in theindustry today.

The TI Eureka Digital AudioBroadcasting (DAB) solution forOEMs includes:

• TI DSP-based digital basebandand TI analog parts

• Evaluation board

• Turn-key reference design

Digital baseband and receiversystemFigure 1 shows the architecture ofthe programmable, TMS320DRE200DSP-based digital baseband andtotal receiver solution. The ETSI 300401-compliant DRE200 DSP base-band performs channel and sourcedecoding on a single chip. In addi-tion, the digital baseband candecode all Eureka modes and per-form user-interface functions. TIalso builds the ADC, DAC, poweramplifier, and various power-man-agement devices for this application.TI’s evaluation board and referencedesign resembles Figure 1.

Features and specifications of theDRE200 DSP baseband are:

• Compatible with standard audioDAC interfaces

• Does not require external memo-ry for DAB operation

• Can interface to an externalmicrocontroller or memory (notrequired for operation)

• Disturbance-free operation dur-

ing multiplex sub-channel recon-figuration or ensemble switch

• Can feed data to external TPEGor MOT decoder and externalmemory

• Baseband <175 mW, standby <1 mA

• 1.6-V operation

• 144-pin TQFP or 144-pin µ*BGA™

• -40 to +85°C operation

Benefits of TI’s total solution• Industry’s lowest cost baseband

and lowest total system BOM

– < $40 for total BOM cost for aDAB receiver

– Integrated baseband leveragingTI’s DSP economy of scale and process technology

– No DRAM/ SRAM, microcon-troller required for audio and PAD decoding

– Software implementation mini-mizes cost to add new features

• Ease of use due to:

– Turn-key reference design:designers can start buildingDAB products in 3–6 months

– Process: license turn-key ref-erence design → customizeuser interface → manufacture

– TI and third-party support cancustomize reference design

– Complete evaluation board

– Local support worldwide

– One-stop shopping for a num-ber of ICs in the receiver

• Software driven, open and scal-able platform gives:

– Flexibility to replace/add anyfeature software modules withTI’s DSP tools (e.g. adding MP3to DAB on the DRE200 DSP).

• Power efficiencies resulting from:

– 175 mW of baseband powerand lowest system power

RoadmapThe DRE200 DSP baseband enableslow-cost basic radios. The futurebaseband products from TI will

redefine digital radio by enablingfeature-rich and integrated endproducts.
