Case Study – OEM Manufacturer of Infotainment Devices  
 


Introduction

  • The Customer A global tier one manufacturer of infotainment devices, mainly Head Units for the Automotive market. The customer's uncompromising quest for quality and perfection has earned it a well-deserved reputation for top-value products and brought them numerous international awards at major competitions all over the globe.
  • The Challenge: Flexible design for easy adaptation to future developments in the dynamic Digital Radio scene (the introduction of DAB+ is such an example), given the automotive design cycle and other automotive related constrains. The optimal solution would use the existing customer's DSP infrastructure to enable fast, low-risk development, and enable the use of the same existing low-cost general-purpose single DSP chip for both the Digital Radio and the customer's applications to enable a cost-efficient end product.
  • The Solution: EtherWaves' ClearSignal Digital Radio solution was selected for integration into the customer's Head Unit. The optimal use of the existing customer's hardware infrastructure and resources (DSP and memory), as well as and performance were a perfect fit for the customer. EtherWaves' reputation as a leader in Digital Radio solutions for the automotive market also helped to influence the decision, and combined to the company's flexibility in adapting its solution to the customer's requirements it became a deciding factor.
